     BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The inventions herein relate to structures, such as dwellings and other buildings for residential occupancy, commercial occupancy and/or material storage, and to components for such structures. 
     Description of the Related Art 
     In the field of residential housing, the traditional technique for building homes is referred to as “stick-built” construction, where a builder constructs housing at the intended location using in substantial part raw materials such as wooden boards, plywood panels, and steel columns The materials are assembled piece by piece over a previously prepared portion of ground, for example, a poured concrete slab or a poured concrete or cinder block foundation. 
     There have been a variety of efforts to depart from the conventional construction techniques used to create dwellings, as well as commercial spaces and like. One of the alternatives to stick-built construction is very generally referred to as modular housing. As opposed to stick-built construction, where the structure is built on-site, a modular house is constructed in a factory and then shipped to the site, often by means of a tractor-trailer. 
     Such modular housing often exceeds in size normally-permitted legal limits for road transport. For example, in the United States the maximum permitted dimensions for road transport are in general 102 inches (259.1 cm) in width, 13.5 feet (4.11 m) in height and 65 to 75 feet (19.81 to 22.86 m) in length. Thus, in many cases transporting a modular house from factory to site requires oversize load permits, which may impose restrictions on when transport can be undertaken and what routes can be utilized. Oversize road regulations may also require the use of an escort car and a trailing car as well. All of these requirements and restrictions inevitably increase the cost of the modular housing. 
     Significant advancements in the construction of dwellings and commercial space are described in U.S. Pat. Nos. 8,474,194, 8,733,029, 10,688,906, 10,829,029 and 10,926,689. In one aspect, these patents pertain to fabricating wall, floor and roof components in a factory that are folded together into a compact shipping module, and which are then transported to the intended location and unfolded to yield a fully formed structure.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     An embodiment of the foldable, transportable structure  150  in which the inventions disclosed herein can be implemented is depicted in  FIGS. 1 through 5 . When fully unfolded, as exemplified by  FIG. 1 , structure  150  has a rectangular shape made of three types of generally planar and rectangular enclosure components  155 , the three types of enclosure components  155  consisting of a wall component  200 , a floor component  300 , and a roof component  400 . As shown in  FIGS. 1 and 2 , the perimeter of structure  150  is defined by first longitudinal edge  106 , first transverse edge  108 , second longitudinal edge  116  and second transverse edge  110 . For convenience, a direction parallel to first longitudinal edge  106  and second longitudinal edge  116  may be referred to as the “longitudinal” direction, a direction parallel to first transverse edge  108  and second transverse edge  110  may be referred to as the “transverse” direction; and a direction parallel to the vertical direction in  FIG. 1  may be referred to as the “vertical” direction. Structure  150  as shown has one floor component  300 , one roof component  400  and four wall components  200 ; although it should be understood that the present inventions are applicable to structures having other configurations as well. 
     Enclosure components  155  (wall component  200 , floor component  300  and roof component  400 ) can be fabricated and dimensioned as described herein and positioned together to form a shipping module  100 , shown end-on in  FIG. 3 . The enclosure components  155  are dimensioned so that the shipping module  100  is within U.S. federal highway dimensional restrictions. As a result, shipping module  100  can be transported over a limited access highway more easily, and with appropriate trailering equipment, transported without the need for oversize permits. Thus, the basic components of structure  150  can be manufactured in a factory, positioned together to form the shipping module  100 , and the modules  100  can be transported to the desired site for the structure, where they can be readily assembled, as described herein. 
     Enclosure Component ( 155 ): General Description 
     The enclosure components  155  of the present invention include a number of shared design features that are described below. 
     A. Laminate Structure Design 
     Enclosure components  155  can be fabricated using a multi-layered, laminate design. A particular laminate design that can be used to fabricate enclosure components  155  comprises a first structural layer  210 , a foam panel layer  213 , a second structural layer  215  and a protective layer  218 , as shown in  FIG. 7  and described further below. 
     In particular, first structural layer  210  is provided in the embodiment of enclosure component  155  that is depicted in  FIG. 7 . First structural layer  210  in the embodiment shown comprises a sheet metal layer  205 , which can be for example galvanized steel or aluminum. Sheet metal layer  205  is made from a plurality of generally planar rectangular metal sheets  206  positioned adjacent to each other to generally cover the full area of the intended enclosure component  155 . 
     Referring again to  FIG. 7 , there is next provided in the depicted embodiment of enclosure component  155  a foam panel layer  213 , comprising a plurality of generally planar rectangular foam panels  214  collectively presenting a first face  211  and a second opposing face  212 . Foam panels  214  are made for example of expanded polystyrene (EPS) foam. A number of these foam panels  214  are positioned adjacent to each other and superposed first face-down on first structural layer  210  to generally cover the full area of the intended enclosure component  155 . The foam panels  214  of foam panel layer  213  preferably are fastened to first structural layer  210  using a suitable adhesive, preferably a polyurethane based construction adhesive. Foam panel layer  213  can include exterior edge reinforcement and interior edge reinforcement, as described further below. 
     In the embodiment of the enclosure component  155  depicted in  FIG. 7 , there is next provided a second structural layer  215 , having a first face that is positioned on the second opposing face  212  of foam panels  214  (the face distal from first structural layer  210 ), and also having a second opposing face. Second structural layer  215  in the embodiment shown comprises a sheet metal layer  216 , which can be for example galvanized steel or aluminum. Sheet metal layer  216  is made from a plurality of generally planar rectangular metal sheets  217  positioned adjacent to each other and superposed first face-down on the second opposing face of foam panel layer  213  to generally cover the full area of the intended enclosure component  155 . The metal sheets  217  of second structural layer  215  preferably are fastened to foam panel layer  213  using a suitable adhesive, preferably a polyurethane based construction adhesive. 
     In the embodiment of the enclosure component  155  depicted in  FIG. 7 , there is optionally next provided a protective layer  218 , having a first face that is positioned on the second opposing face of second structural layer  215  (the face distal from foam panel layer  213 ), and also having a second opposing face. Optional protective layer  218  in the embodiment shown comprises a plurality of rectangular structural building panels  219  principally comprising an inorganic composition of relatively high strength, such as magnesium oxide (MgO). The structural building panels  219  are positioned adjacent to each other and superposed first face-down on the second opposing face of second structural layer  215  to generally cover the full area of the intended enclosure component  155 . The building panels  219  of protective layer  218  preferably are fastened to second structural layer  215  using a suitable adhesive, preferably a polyurethane based construction adhesive. Protective layer  218  can be used if desired to impart a degree of fire resistance to the enclosure component  155 , as well as to provide a pleasing texture and/or feel. 
     Other embodiments of multi-layered, laminate designs, which can be used to fabricate the enclosure components  155  of the present invention, are described in U.S. Nonprovisional patent application Ser. No. 16/786,130, entitled “Foldable Building Structures with Utility Channels and Laminate Enclosures,” filed on Feb. 10, 2020, which has issued as U.S. Pat. No. 11,118,344. The contents of that U.S. Nonprovisional patent application Ser. No. 16/786,130, entitled “Foldable Building Structures with Utility Channels and Laminate Enclosures” and filed on Feb. 10, 2020 are incorporated by reference as if fully set forth herein, particularly including the multi-layered, laminate designs described for example at ¶¶ 0034-57 and depicted in  FIGS. 4A-4D  thereof. 
     B. Enclosure Component Exterior Edge Reinforcement 
     The exterior edges of each enclosure component  155  (i.e., the edges that define the perimeter of enclosure component  155 ) can be provided with exterior edge reinforcement, as desired. Exterior edge reinforcement generally comprises an elongate, rigid member which can protect the foam panel material of foam panel layer  213  that would otherwise be exposed at the exterior edges of enclosure components  155 . Exterior edge reinforcement can be fabricated from one or more of laminated strand lumber board, wooden board, C-channel extruded aluminum or steel, or the like, and is generally secured to the exterior edges of enclosure component  155  with fasteners, such as screw or nail fasteners, and/or adhesive. 
     C. Enclosure Component Partitioning 
     Enclosure components  155  in certain instances are partitioned into enclosure component portions to facilitate forming a compact shipping module  100 . In those instances where an enclosure component  155  is partitioned into enclosure component portions, any exterior edge reinforcement on the exterior edges defining the perimeter of the enclosure component is segmented as necessary between or among the portions. 
     The enclosure component portions can be joined by hinge structures or mechanisms to permit the enclosure component portions to be “folded” and thereby contribute to forming a compact shipping module  100 . 
     D. Enclosure Component Interior Edge Reinforcement 
     An enclosure component  155  partitioned into enclosure component portions will have interior edges. There will be two adjacent interior edges for each adjacent pair of enclosure component portions. Such interior edges can be provided with interior edge reinforcement. Similar to exterior edge reinforcement, such interior edge reinforcement generally comprises an elongate, rigid member which can protect the foam panel material of foam panel layer  213  which would otherwise be exposed at the interior edges of enclosure components  155 . Interior edge reinforcement can be fabricated from one or more of laminated strand lumber board, wooden board, C-channel extruded aluminum or steel, or the like, and is generally secured to the interior edges of enclosure component  155  with fasteners, such as screw or nail fasteners, and/or adhesive. 
     E. Enclosure Component Load Transfer 
     In the case of enclosure components  155 , it is necessary to transfer the loads imposed on their surfaces to their exterior edges, where those loads can be transferred either to or through adjoining walls, or to the building foundation. For enclosure components  155  that are horizontally oriented when in use (floor component  300  and roof component  400 ), such loads include the weight of equipment, furniture and people borne by their surfaces, as well as vertical seismic loads. For enclosure components that are vertically oriented when in use (wall component  200 ), such loads include those arising from meteorological conditions (hurricanes, tornadoes, etc.) and human action (vehicle and other object impacts). 
     For this purpose, multi-layered, laminate designs as shown in  FIG. 7  will function to transfer the loads described above. To add additional load transfer capability, structural members, such as beams and/or joists, can be utilized within the perimeter of the enclosure components  155 , as is deemed appropriate to the specific design of structure  150  and the particular enclosure component  155 , to assist in the transfer of loads to the exterior edges. Particular embodiments of such structural members, which also incorporate hinge structures, are described in U.S. Provisional Patent Application No. 63/188,101, filed May 13, 2021, entitled “Folding Beam Systems” and having the same inventors as this disclosure. 
     Further design details of wall component  200 , floor component  300 , and roof component  400  are provided in the sections following. 
     Wall Component ( 200 ) 
     Typically, structure  150  will utilize four wall components  200 , with each wall component  200  corresponding to an entire wall of structure  150 . 
     A. General Description 
     Wall component  200  has a generally rectangular perimeter. As shown in  FIG. 1 , wall components  200  have plural apertures, specifically a door aperture  202 , which has a door frame and door assembly, and plural window apertures  204 , each of which has a window frame and a window assembly. The height and length of wall components  200  can vary in accordance with design preference, subject as desired to the dimensional restrictions applicable to transport, described above. In this disclosure, structure  150  is fashioned with all sides of equal length; accordingly, its first and second longitudinal edges  106  and  116 , and its first and second transverse edges  108  and  110 , are all of equal length. It should be understood however, that the inventions described herein are applicable to structures having other dimensions, such as where two opposing wall components  200  are longer than the other two opposing wall components  200 . 
     As indicated above, wall components  200  of the present inventions can utilize a multi-layered, laminate design. In the embodiment depicted in  FIGS. 1 through 6 , wall component  200  utilizes the multi-layered, laminate design shown in  FIG. 7  employing these particular elements: sheet metal layer  205  of first structural layer  210  is 24 gauge galvanized steel approximately 0.022-0.028 inch thick, the foam panels  214  of foam panel layer  213  are EPS foam approximately 5.68 inches thick, the sheet metal layer  216  of second structural layer  215  is 24 gauge galvanized steel approximately 0.022-0.028 inch thick, and the building panels  219  of protective layer  218  are MgO board approximately 0.25 inch (6 mm) thick. 
     The perimeter of each wall component  200  is generally provided with exterior edge reinforcement. As exemplified by wall component  200  shown in  FIG. 6 , the exterior edge reinforcement for wall component  200  is a floor plate  220  along the bottom horizontal edge, a ceiling plate  240  along the top horizontal edge and two end pieces  270  respectively fastened at each vertical edge of wall component  200 . In the case of a wall component  200 , exterior edge reinforcement provides regions for fastening like regions of abutting wall components  200 , roof component  400  and floor component  300 , in addition to protecting the exterior edges of foam panel material. 
     In the embodiment shown in  FIGS. 1 through 6 , the exterior edge reinforcement for wall component  200  provided by floor plate  220 , ceiling plate  240 , and end pieces  270  is fabricated from laminated strand lumber board 5.625″ deep and 1.5″ thick. 
     B. Partitioned Wall Components 
     Referring to  FIG. 2 , structure  150  has two opposing wall components  200 , where one of the two opposing wall components  200  comprises first wall portion  200   s - 1  and second wall portion  200   s - 2 , and the other of the two opposing wall components  200  comprises third wall portion  200   s - 3  and fourth wall portion  200   s - 4 . Each of wall portions  200   s - 1 ,  200   s - 2 ,  200   s - 3  and  200   s - 4  has a generally rectangular planar structure. As shown in  FIG. 2 , the interior vertical edge  192 - 1  of wall portion  200   s - 1  is proximate to a respective interior vertical edge  192 - 2  of wall portion  200   s - 2 , and the interior vertical edge  194 - 3  of wall portion  200   s - 3  is proximate a respective interior vertical wall edge  194 - 4  of wall portion  200   s - 4 . Interior edge reinforcement can be provided at any one or more of vertical edges  192 - 1 ,  192 - 2 ,  194 - 3  and  194 - 4 . In the embodiment shown in  FIGS. 1 through 6 , the interior edge reinforcement provided at vertical edges  192 - 1 ,  192 - 2 ,  194 - 3  and  194 - 4  is fabricated from laminated strand lumber board 5.625″ deep and 1.5″ thick. 
     Referring again to  FIG. 2 , first wall portion  200   s - 1  is fixed in position on floor portion  300   a  proximate to first transverse edge  108 , and third wall portion  200   s - 3  is fixed in position on floor portion  300   a,  opposite first wall portion  200   s - 1  and proximate to second transverse edge  110 . First wall portion  200   s - 1  is joined to second wall portion  200   s - 2  with a hinge structure that permits wall portion  200   s - 2  to pivot about vertical axis  192  between a folded position and an unfolded position, and third wall portion  200   s - 3  is joined to fourth wall portion  200   s - 4  with a hinge structure to permit fourth wall portion  200   s - 4  to pivot about vertical axis  194  between a folded position and an unfolded position. 
     Notably, first wall portion  200   s - 1  is longer than third wall portion  200   s - 3  by a distance approximately equal to the thickness of wall component  200 , and second wall portion  200   s - 2  is shorter than third wall portion  200   s - 3  by a distance approximately equal to the thickness of wall component  200 . Furthermore, wall portion  200   s - 1  and wall portion  200   s - 3  are each shorter in length (the dimension in the transverse direction) than the dimension of floor portion  300   a  in the transverse direction. Dimensioning the lengths of wall portions  200   s - 1 ,  200   s - 2 ,  200   s - 3  and  200   s - 4  in this manner permits wall portions  200   s - 2  and  200   s - 4  to nest against each other in an overlapping relationship when in an inwardly folded position. In this regard,  FIG. 2  depicts wall portions  200   s - 2  and  200   s - 4  both in their unfolded positions, where they are labelled  200   s - 2   u  and  200   s   4 - u  respectively, and  FIG. 2  also depicts wall portions  200   s - 2  and  200   s - 4  both in their inwardly folded positions, where they are labelled  200   s - 2   f  and  200   s   4 - f  respectively. When wall portions  200   s - 2  and  200   s - 4  are in their inwardly folded positions ( 200   s - 2   f  and  200   s - 4   f ), they facilitate forming a compact shipping module. When wall portion  200   s - 2  is in its unfolded position ( 200   s - 2   u ), it forms with wall portion  200   s - 1  a wall component  200  proximate first transverse edge  108 , and when wall portion  200   s - 4  is in its unfolded position ( 200   s - 4   u ), it forms with wall portion  200   s - 3  a wall component  200  proximate second transverse edge  110 . 
     The hinge structures referenced for securing first wall portion  200   s - 1  to second wall portion  200   s - 2 , and third wall portion  200   s - 3  to fourth wall portion  200   s - 4 , can be surface mounted or recessed, and of a temporary or permanent nature. The provision of interior edge reinforcement, as described above, can provide a region for securing such hinge structures. Suitable hinge structures can be fabricated for example of ferrous or non-ferrous metal, plastic or leather material. 
     C. Unpartitioned Wall Components 
     As compared to the two wall components  200  proximate first and second transverse edges  108  and  110 , which are partitioned into wall portions, the remaining two wall components  200  proximate first and second longitudinal edges  106  and  116  do not comprise plural wall portions, but rather each is a single piece structure. However, one of these wall components  200 , which is sometimes denominated  200 P in this disclosure, and which is located on floor portion  300   b  proximate first longitudinal edge  106 , is pivotally secured to floor portion  300   b  by means of hinge structures to permit wall component  200 P to pivot about horizontal axis  105  shown in  FIG. 3  from a folded position to an unfolded position. Pivotally securing wall component  200 P also facilitates forming a compact shipping module  100 . The remaining wall component  200 , sometimes denominated  200 R in this disclosure, is rigidly secured on floor portion  300   a  proximate second longitudinal edge  116  and abutting the vertical edges of first wall portion  200   s - 1  and third wall portion  200   s - 3  proximate to second longitudinal edge  116 , as shown in  FIG. 2 . 
     The hinge structures described above, for securing wall component  200 P to floor portion  300   b,  can be surface mounted or recessed, and of a temporary or permanent nature. The provision of exterior edge reinforcement, as described above, can provide a region for securing such hinge structures. Suitable hinge structures can be fabricated for example of ferrous or non-ferrous metal, plastic or leather material. 
     Floor Component ( 300 ) 
     Typically, structure  150  will utilize one floor component  300 ; thus floor component  300  generally is the full floor of structure  150 . 
     A. General Description 
     Floor component  300  has a generally rectangular perimeter.  FIGS. 4 and 5  depict floor component  300  in accordance with the present inventions.

     Roof Component ( 400 ) 
     Typically, structure  150  will utilize one roof component  400 ; thus roof component  400  generally is the full roof of structure  150 . 
     A. General Description 
     Roof component  400  has a generally rectangular perimeter.  FIGS. 1, 4 and 5  depict roof component  400  in accordance with the present inventions. The perimeter of roof component  400  is defined by first longitudinal roof edge  406 , first transverse roof edge  408 , second longitudinal roof edge  416  and second transverse roof edge  410 . In particular, (a) first longitudinal roof edge  406 , (b) first transverse roof edge  408 , (c) second longitudinal roof edge  416  and (d) second transverse roof edge  410  of roof component  400  generally coincide with (i.e., overlie) (w) first longitudinal edge  106 , (x) first transverse edge  108 , (y) second longitudinal edge  116  and (z) second transverse edge  110 , respectively, of structure  150 . 
     The length and width of roof component  400  can vary in accordance with design preference. In the particular embodiment of structure  150  depicted in  FIGS. 1, 4 and 5 , the length and width of roof component  400  approximates the length and width of floor component  300 . 
     Roof component  400  and its constituent elements are generally designed and dimensioned in thickness and in other respects to accommodate the particular loads to which roof component  400  may be subject. It is preferred that roof component  400  utilize a multi-layered, laminate design, such as that described in connection with  FIG. 7 . In the embodiment shown in  FIGS. 4 and 5 , the top-most surface of roof component  400  comprises sheet metal layer  205  of first structural layer  210 , with sheet metal layer  205  being 24 gauge galvanized steel approximately 0.022-0.028 inch thick. Below sheet metal layer  205  there are provided foam panels  214  of foam panel layer  213 , with foam panels  214  in the embodiment shown in  FIGS. 4 and 5  being EPS foam approximately 7.125 inches thick.

     The perimeter of roof component  400  is generally provided with exterior edge reinforcement. As exterior edge reinforcement for the embodiment of roof component  400  shown in  FIGS. 4 and 5 , a first shoulder beam  435  (visible edge-on in  FIG. 4 ) is positioned at the first longitudinal roof edge  406  of roof component  400 , a second shoulder beam  435  (visible edge-on in  FIG. 5 ) is positioned at the first transverse roof edge  408  of roof component  400 , a third shoulder beam  435  (visible edge-on in  FIG. 5 ) is positioned at the second transverse roof edge  410  of roof component  400 , and a fourth shoulder beam  435  (visible edge-on in  FIG. 4 ) is positioned at the second longitudinal roof edge  416  of roof component  400 . In addition to protecting the exterior edges of foam panel material, the exterior edge reinforcement provided by shoulder beams  435  assists in resisting vertical loads and transferring such loads to lower floors through underlying wall components  200  supporting roof component  400 , and then to the foundation of the structure  150 . Such exterior edge reinforcement can also provide a region for fastening like regions of abutting enclosure components  155  (underlying and any overlying). Shoulder beams  435  of roof component  400  can be fabricated from laminated strand lumber board 7.125″ deep and 1.5″ thick. 
     B. Roof Partitioning 
     The roof component  400  of structure  150  is partitioned into roof portions  400   a,    400   b  and  400   c.    FIG. 1  shows roof portions  400   a,    400   b  and  400   c  in perspective view, and  FIG. 4  shows roof portions  400   a,    400   b  and  400   c  in section view, edge-on. 
     Each of the roof portions  400   a,    400   b  and  400   c  is a planar generally rectangular structure, with roof portion  400   a  adjoining roof portion  400   b,  and roof portion  400   b  adjoining roof portion  400   c.  Interior edge  412   c  of roof component  400   c  abuts a first interior edge  412   b  of roof component  400   b,  as shown in  FIG. 4 . For interior edge reinforcement, a reinforcing board  437  is positioned adjacent interior edge  412   c,  and a reinforcing board  437  is positioned against first interior edge  412   b.  Interior edge  412   a  of roof portion  400   a  abuts a second interior edge  412   b  of roof portion  400   b,  as shown in  FIG. 4 . For interior edge reinforcement, a reinforcing board  437  is positioned adjacent interior edge  412   a,  and a reinforcing board  437  is positioned against second interior edge  412   b.  Additional structural members, such as beams and/or joists, can be utilized within the perimeter of one or more of roof portions  400   a,    400   b  and  400   c,  as is deemed appropriate to the specific design of structure  150  and roof component  400 , to assist in the transfer of vertical loads to one or more shoulder beams  435 . 
     Referring to structure  150  shown in  FIG. 4 , roof portion  400   a  is fixed in position relative to first wall portion  200   s - 1 , third wall portion  200   s - 3  and wall component  200 R. Roof portion  400   a  is joined to roof portion  400   b  with hinge structures provided between interior edge  412   a  of roof portion  400   a  and second interior edge  412   b  of roof portion  400   b.  Such hinge structures are adapted to permit roof portion  400   b  to pivot through up to one hundred and eighty degrees (180°) of arc about a horizontal axis  405   a,  located proximate the top of roof component  400  and shown in  FIG. 4 , between the fully folded position shown in  FIG. 3 , where roof portion  400   b  lies flat against roof portion  400   a,  and the fully unfolded position shown in  FIG. 4 . 
     In turn, roof portion  400   b  is joined to roof portion  400   c  with hinge structures provided between first interior edge  412   b  of roof portion  400   b  and interior edge  412   c  of roof portion  400   c.  Such hinge structures are adapted to permit roof portion  400   c  to pivot through up to one hundred and eighty degrees (180°) of arc about a horizontal axis  405   b,  located proximate the bottom of roof component  400  and shown in  FIG. 4 , between the folded position shown in  FIG. 3 , where roof portion  400   c  lies flat against roof portion  400   b  (when roof portion  400   b  is positioned to lie flat against roof portion  400   a ), and the fully unfolded position shown in  FIG. 4 . 
     The hinge structures joining roof portions  400   a,    400   b  and  400   c  can be surface mounted or recessed, and of a temporary or permanent nature. Suitable hinge structures can be fabricated for example of ferrous or non-ferrous metal, plastic or leather material. The interior edge reinforcement provided by reinforcing boards  437  of roof portions  400   a,    400   b  and  400   c  can provide a region for mounting hinge structures, in addition to protecting the edges of foam panel material.

     Enclosure Component Sealing Systems 
     Structure  150  can utilize the enclosure component sealing systems described below to limit or prevent the ingress of rain water, noise and outside air into the interior of structure  150 . 
     A. General Description 
     The enclosure component sealing systems for structure  150  utilize the sealing structures described below. Except for I-beam end cap  221 , which functions to seal the edges of select enclosure components  155 , the enclosure component sealing systems comprise in general terms two enclosure component sealing structures, paired in in pressing contact in different combinations, to seal the junctions between different regions of the enclosure components  155  found in structure  150 . These junctions consist of either two interior edges of adjacent enclosure component portions, positioned edge-to-edge when structure  150  is unfolded, or an exterior edge of an enclosure component  155  which abuts an interior surface of another enclosure component  155 . Where an enclosure component sealing structure is positioned on an interior or exterior edge of an enclosure component  155 , there can respectively be provided interior edge reinforcement or exterior edge reinforcement between the sealing structure and the respective interior or exterior edge of the foam panel layer  213  in the case where the multi-layered, laminate design depicted in  FIG. 7  is utilized (such that the enclosure component sealing structure is positioned proximate to the interior or exterior edge, as the case may be, of the foam panel layer  213 ). The specific enclosure component sealing structures described below are I-beam end cap  221 ; wall vertical interlock  245 ; wall end cap  246 ; I-beam interlock A  250 ; I-beam interlock B  251 ; floor top plate  252 ; roof bottom plate  255 ; floor top interlock  261 ; wall end interlock A  262 ; and wall end interlock B  263 . Excepting I-beam end cap  221 , each of the foregoing enclosure component sealing structures utilizes either two or more compression seals  230 , or one shear seal  260 , which are also described below. 
     The current inventions include two closure boards, namely perimeter board  310  and roof skirt board  280 . These closure boards, which are described below, are utilized in conjunction with I-beam end cap  221  to provide additional sealing, as well as to realize additional benefits. 
     B. I-Beam End Cap ( 221 ) 
     I-beam end cap  221 , shown in cross-section in  FIG. 10 , is a rigid elongate member that is fastened to the periphery of select enclosure components  155 , preferably the exterior edges of floor component  300  and roof component  400 . I-beam end cap  221  constitutes an edge seal that performs a sealing function against water ingress into and environmental exposure of the edge of the enclosure component  155  to which it is secured, and imparts impact resistance to that edge. 
       FIG. 10  shows an exemplary installation of I-beam end cap  221  secured to the edge of a schematic representation of floor portion  300   a.  In particular, I-beam end cap  221  has an elongate seal plate  223  with seal plate  223  having an elongate interior face  226  and an opposing elongate planar exterior face  227 . I-beam end cap  221  has a length and width the same, or substantially the same, as the length and width of the exterior edge of floor portion  300   a,  so as to cover the entirety, or substantially the entirety, of the exterior edge of floor portion  300   a.    
     At the mid-point of the interior face  226  of seal plate  223 , there is provided an elongate key  222 , which is rectangular in cross section (as shown in  FIG. 10 ), and has a length the same, or substantially the same, as the length of I-beam end cap  221 . Key  222  is received in a corresponding slot formed in the exterior edge reinforcement positioned on the exterior edge of the enclosure component  155  to which I-beam end cap  221  is secured. Thus for example,  FIG. 24A  depicts key  222  of an I-beam end cap  221  received in slot  422  of a shoulder beam  435  of roof portion  400   a.  Each of the top and bottom edges of I-beam end cap  221  define locating slots  229 . In the case where the enclosure component  155  utilizes the enclosure component laminate design shown in  FIG. 7 , locating slots  229  receive the edge portions of sheet metal layers  205  and  216 , bent down at a ninety degree (90°) angle. 
     Still referring to  FIG. 10 , the exterior face  227  of seal plate  223  of I-beam end cap  221  includes an elongate accessory slot  224 , which is rectangular in cross section and has a length the same, or substantially the same, as the length of the exterior face  227  of I-beam end cap  221 . The exterior face  227  further includes a plurality of elongate fastener locating grooves  225 , each of which has a length the same, or substantially the same, as the length of seal plate  223 . I-beam end cap  221  can be secured to an exterior edge of an enclosure component  155 , such as the floor portion  300   a  shown in  FIG. 10  and the roof portion  400   a  shown in  FIG. 24A , for example by adhesive applied to interior face  226 , or by fasteners, such as screw or nail fasteners, spaced apart along the length of I-beam end cap  221  and driven through the exterior face  227 , or by utilizing a combination of adhesive and fasteners. Locating grooves  225  assist in accurate positioning of such fasteners. 
     C. Compression Seal ( 230 ) 
     A number of the enclosure component sealing systems described herein and utilized in structure  150  include a compression seal system. An element of that compression seal system is a compression seal  230 . 
     Compression seal  230 , which is shown in cross-section in  FIG. 11A , is an elongate member having in cross-section an elongate base  231  with an elongate arched portion  232  that is flanked by two elongate winglets  233 . At the intersection of the arched portion  232  of base  231  and each of the winglets  233 , there are provided two opposed elongate seal walls  234 , joined to and extending away from base  231  in a diverging relationship at a divergence angle θ, where θ&lt;180°, for example θ&lt;90° or in the range of 40°&lt;θ&lt;50°. It is most preferred that θ be the same, or nearly so, as the divergence angle of the slot walls  244  described below. Thus as shown in  FIG. 11A , the ends of the seal walls  234  distal from base  231  are further apart than the ends of the seal walls proximate to base  231 . 
     At the ends of the seal walls  234  distal from base  231 , each seal wall  234  is joined to an elongate arcuate buttress  235 . The end of each arcuate buttress  235 , distal from the seal wall  234  to which it is joined, is in turn joined to a respective planar elongate seal surface  236 ; thus there are two planar seal surfaces  236  in compression seal  230 . The planar seal surfaces  236  extend away from the seal walls  234  in a converging relationship at a convergence angle δ, where δ&lt;180°, for example 90°. Thus the ends of seal surfaces  236  distal from arcuate buttresses  235  are closer together than the ends of seal surfaces  236  proximate to arcuate buttresses  235 . The ends of seal surfaces  236  distal from arcuate buttresses  235  are joined by an elongate seal closure  237 . The base  231 , seal walls  234 , arcuate buttresses  235 , seal surfaces  236  and seal closure  237  thereby define a hollow elongate seal chamber  238 , as shown in  FIG. 11A . Seal closure  237  is curved in shape toward seal chamber  238 , such as to assume a cupped appearance. 
     Seal  230  is intended to be received in an elongate seal slot  240 , shown for example in  FIG. 11B . Slot  240  in general has a dovetail shape, with an elongate planar floor  241  flanked by two elongate lateral grooves  242 , and with an elongate planar slot wall  244  abutting and extending from each groove  242  toward an elongate shoulder  243  at the surface of the slot  240 . Thus there are two opposed shoulders  243  in seal slot  240 . The planar slot walls  244  extend away from grooves  242  in a diverging relationship at a divergence angle ε, where ε&lt;180° (for example ε&lt;90° or in the range of 40°&lt;ε&lt;50°), such that the edges of slot walls  244  coincident with shoulders  243  are further apart than the edges of slot walls  244  abutting grooves  242 . Compression seal  230  is dimensioned to snugly fit within slot  240 , as shown in  FIG. 11B , such that winglets  233  are received in grooves  242  and the arched portion  232  of base  231  is compressed sufficiently to provide a resilient force that urges winglets  233  into grooves  242  and causes seal  230  to be retained in its proper position in slot  240  during fabrication and following fabrication of the enclosure component  155 . 
     When two enclosure components  155  on which are mounted two paired enclosure component sealing structures, one of which bears a compression seal  230 , are appropriately positioned and pressed together, compression seal  230  will be squeezed against the planar exterior face  227  of the opposed seal plate  223 , which causes seal closure  237  and arcuate buttresses  235  to be urged into seal chamber  238 . This permits the two planar exterior faces  227  of the pressed-together seal plates  223  of the paired sealing structures to come into full contact. At the same time, arcuate buttresses  235  rotate down and seal surfaces  236  are urged into a generally coplanar relationship (with arcuate buttresses  238  functioning as hinges) with the opposing planar exterior face  227  pressing against it, to create two lines of sealing. 
     Compression seal  230  can be fabricated from a resilient material, such as rubber or plastic, for example polyurethane. Particular embodiments of enclosure component sealing structures utilizing the foregoing compression sealing system are described below.

At the intersection of base  231  and each of the winglets  233 , there is provided two opposed elongate seal walls  234  (individually referred to as seal walls  234 A,  234 B), joined to and extending away from base  231  in a diverging relationship at a divergence angle λ where λ&lt;180°, for example λ&lt;90° or in the range of 40°&lt;λ&lt;50°. It is most preferred that λ be the same, or nearly so, as the divergence angle ε of the slot walls  244  shown in  FIG. 11B . Thus as shown in  FIG. 16A , the ends of the seal walls  234  distal from base  231  are further apart than the ends of the seal walls  234  proximate to base  231 . 
     At the end of seal wall  234 B distal from base  231 , seal wall  234 B is joined to an elongate seal closure  237 , a planar surface oriented at an upward angle α (relative to the planar orientation of base  231 ) away from seal wall  234 B in a direction toward an elongate seal support  239 , described below, with α&lt;90°. A planar cantilevered seal surface  257  is joined to the edge of seal closure  237  that is distal from seal wall  234 B, as shown in  FIG. 16A . 
     At the end of seal wall  234 A distal from base  231 , seal wall  234 A is joined to the elongate seal support  239 . Proximate to seal wall  234 A, seal support  239  comprises an elongate planar region oriented parallel to base  231 . Distal from seal wall  234 A, seal support  239  comprises an elongate arcuate buttress region. The edge of the arcuate buttress region of seal support  239 , which is distal from seal wall  234 A, joins cantilevered seal surface  257  proximate to the junction of cantilevered seal surface  257  and seal closure  237  to define a hollow seal chamber  238 . Planar cantilevered seal surface  257  is oriented at an upward angle β away from the junction of arcuate buttress  235  and seal closure  237  and terminates at a free end  258 , with β&lt;90°, for example β&gt;α. 
     Shear seal  260  is intended to be received in an elongate seal slot  240 , shown for example in  FIG. 16B , which has the same geometry as the seal slots  40  utilized to receive compression seals  230 . Shear seal  260  is dimensioned to snugly fit within slot  240 , such that winglets  233  of seal  260  are received in grooves  242  of slot  240 . An exemplary placement of a shear seal  260  is depicted in  FIG. 16B , which shows a shear seal  260  placed within the slot  240  of a wall end interlock A  262 , described further below. As can be seen, when shear seal  260  is properly positioned in slot  240 , both seal wall  234 A and seal wall  234 B terminate below the level of exterior face  227  of wall end interlock A  262 , with seal wall  234 A (underlying planar cantilevered seal surface  257 ) terminating below the level at which seal wall  234 B terminates. 
     Shear seal  260  is preferably utilized where two enclosure components  155  are laterally moved during unfolding, one over the other. In such an instance, the two enclosure components  155  are provided with paired enclosure component sealing structures, with one enclosure component sealing structure mounted on one of the enclosure components  155  (such as on an exterior edge), and the other enclosure component sealing structure mounted on the other of the enclosure component structures  155  (such as on an interior face). Each of the paired enclosure component sealing structures has a shear seal  260 , with the two shear seals  260  being oppositely oriented; that is to say, the cantilevered seal surface  257  of each is oriented away from the cantilevered seal surface  257  of the other, and each is oriented in the direction of relative movement. Thus in the case of each of the two shear seals  260 , the lateral movement of one enclosure component  155 , relative to the other, is in the direction from seal wall  234 B toward seal wall  234 A. This lateral movement flattens the cantilevered seal surface  257 , as well as the seal closure  237 , and squeezes down each shear seal  260 , such that its seal closure  237  and seal support  239  are urged into seal chamber  238 . This permits the opposing planar exterior faces  227  of each of the two enclosure component sealing structures to come into full contact. At the same time, the cantilevered seal surface  257  and seal closure  237  of each shear seal  260  are urged into a generally coplanar relationship, with the planar exterior face  227  of the opposing enclosure component seal structure pressing against them, to create an elongate area of sealing. 
     Shear seal  260  can be fabricated from a resilient material, such as rubber or plastic, for example polyurethane. Particular embodiments of enclosure component sealing structures utilizing the foregoing compression sealing system are described below. 
     I. Wall End Interlock A ( 262 ), Floor Top Interlock ( 261 ) Sealing System 
       FIG. 17  depicts in exploded form the junction between a floor top interlock  261  and a wall end interlock A  262 , each shown in cross-section. The particular junction is shown for illustrative purposes between wall portion  200   s - 2  and floor portion  300   b,  with floor top interlock  261  positioned along the upper face of floor portion  300   b  adjacent first transverse floor edge  120 , and with wall end interlock A  262  positioned on the bottom edge of wall portion  200   s - 2 . In structure  150 , wall portion  200   s - 2  in  FIG. 17  is vertically oriented and floor portion  300   b  is horizontally oriented. 
     In particular, floor top interlock  261  shown in  FIG. 17  is a rigid elongate member that has an elongate seal plate  223  with an interior face  226  and an opposing planar exterior face  227 . The exterior face  227  preferably is hard and smooth to provide a good sealing surface. Seal plate  223  has a length the same, or substantially the same, as the dimension of floor portion  300   b  coinciding with first transverse floor edge  120 , so as to cover the top edge of floor portion  300   b  proximate to first transverse floor edge  120 . Seal plate  223  of floor top interlock  261  has a width the same, or substantially the same, as the width of wall portion  200   s - 2 . The floor top interlock  261  preferably has a thickness “J” at its interior edge, as shown in  FIG. 17 , sufficient to accommodate the thickness of any protective layer  218  and/or flooring used to surface floor portion  300   b,  such as stone, wood or carpeting. 
     As shown in  FIG. 17 , at the exterior edge of the interior face  226  of floor top interlock  261 , adjacent first transverse floor edge  120 , there is provided a series of elongate stepped locating ridges  254 . These stepped locating ridges  254 , which have a length the same, or substantially the same, as the length of floor top interlock  261 , mesh with the corresponding stepped locating ridges  253 . shown on the wall end cap  221  depicted in  FIG. 10 . Such a wall end cap  221  is located at the exterior edge of wall portion  300   b,  as indicated in  FIG. 17  by dashed lines. 
     Still referring to  FIG. 17 , an elongate seal slot  240  is defined on the exterior face  227  of floor top interlock  261 , proximate to the exterior edge of floor portion  300   b  (such exterior edge coincides with first transverse floor edge  120 ). Seal slot  240  has a length the same, or substantially the same, as the length of floor top interlock  261 . 
     Floor top interlock  261  can be secured to the top edge of floor portion  300   b  at first transverse floor edge  120  shown in  FIG. 17  for example by adhesive applied to interior face  226 , or by fasteners, such as screw or nail fasteners, spaced apart along the length of floor top interlock  261  and driven through the exterior face  227 , or by utilizing a combination of adhesive and fasteners. 
     Wall end interlock A  262 , also shown in  FIG. 17 , is a rigid elongate member that has an elongate seal plate  223  with an interior face  226  and an opposing exterior face  227 . The exterior face  227  preferably is hard and smooth to provide a good sealing surface. The seal plate  223  of wall end interlock A  262  has a length and width the same, or substantially the same, as the length and width of the bottom edge of wall portion  200   s - 2 , so as to cover the entirety, or substantially the entirety, of the bottom edge of wall portion  200   s - 2 , as shown in in  FIG. 17 . 
     At the mid-point of the interior face  226  of seal plate  223  of wall end interlock A  262 , there is provided an elongate key  222 , which has a rectangular cross section and a length the same, or substantially the same, as the length of wall end interlock A  262 . Key  222  is received in a corresponding elongate slot formed in the exterior edge reinforcement positioned on the bottom edge of the wall portion  200   s - 2  to which wall end interlock A  262  is secured. 
     Again referring to  FIG. 17 , an elongate seal slot  240  is defined on the exterior face  227  of wall end interlock A  262 , toward the interior edge of wall end interlock A  262  (distal from first transverse floor edge  120 ). This seal slot  240  has a length the same, or substantially the same, as the length of wall end interlock A  262 . Additionally, each of the interior and exterior edges of wall end interlock A  262  define locating slots  229 . In the case where the enclosure component  155 , in this case wall portion  200   s - 2 , utilizes the enclosure component laminate design shown in  FIG. 7 , locating slots  229  receive the edge portions of sheet metal layers  205  and  216 , bent down at a ninety degree (90°) angle. 
     Wall end interlock A  262  can be fastened to the bottom edge of wall portion  200   s - 2  for example by adhesive applied to its interior face  226 , or by fasteners, such as screw or nail fasteners, spaced apart along the length of wall end interlock A  262  and driven through its exterior face  227 , or by utilizing a combination of adhesive and fasteners. 
     In  FIG. 17 , floor top interlock  261  mates with wall end interlock A  262 . Prior to mating, a shear seal  260  is placed in the seal slot  240  of floor top interlock  261 , and a shear seal  260  is placed in the seal slot  240  of wall end interlock A  262 . The shear seals  260  placed in the seals slots  240  of floor top interlock  261  and wall end interlock A  262  each has the same, or approximately the same, length as the slot  240  in which it is inserted. 
     Mating of floor top interlock  261  with wall end interlock A  262  occurs by the bottom edge of wall portion  200   s - 2  moving over the top surface of floor portion  300   b,  from a folded position to an unfolded position. Thus in the arrangement shown in  FIG. 17 , such mating will correspond to a movement of wall portion  200   s - 2  from the right-hand side of the figure toward the left, with wall end interlock A  262  sliding over floor top interlock  261  until the fully unfolded position is reached. In that fully unfolded position, the shear seal  260  in floor top interlock  261 , and particularly its seal surface  257 , will be in pressing contact with the exterior face  227  of wall end interlock A  262 ; and the shear seal  260  in wall end interlock A  262 , and particularly its seal surface  257 , will be in pressing contact with the exterior face  227  of floor top interlock  261 . Consistent with this movement, the shear seal  260  placed in seal slot  240  of floor top interlock  261  is preferably oriented so that the free end  258  of its cantilevered seal surface  257  is directed toward the exterior edge of floor top interlock  261  (toward first transverse floor edge  120 ), and the shear seal  260  placed in the seal slot  240  of wall end interlock A  262  is preferably oriented so that the free end  258  of its cantilevered seal surface  257  is directed toward the interior edge of wall end interlock A  262  (away from first transverse floor edge  120 ). 
     To facilitate mating, it is preferred that planar exterior face  227  of floor top interlock  261  not be parallel to the interior face  226  of floor top interlock  261 , or to the top face of wall portion  300   b,  but rather be inclined downward, in the direction moving away from first transverse floor edge  120 , at an angle γ, as shown in  FIG. 17 . Likewise, it is preferred that planar exterior face  227  of wall end interlock A  262  be inclined upward, in the direction moving toward first transverse floor edge  120 , at the same angle γ, as shown in  FIG. 17 . Accordingly, when bottom edge of wall portion  200   s - 2  moves over the top surface of floor portion  300   b,  from a folded position to an unfolded position, the shear seals  260  located in slots  240  of floor top interlock  261  and wall end interlock A  262  will be compressed by the sliding movement of wall end interlock A  262  to provide two elongate sealing areas between floor portion  300   b  and wall portion  200   s - 2 . Also to facilitate mating, there is shown in  FIG. 17  a step-down  268  on the exterior face  227  of wall end interlock A  262 . Step-down  268  is an abrupt reduction in the thickness of wall end interlock A  262 , in the direction moving from the inside edge of wall end interlock A  262  toward the outside edge of wall end interlock A  262 , which outside edge in the case of the junction depicted in  FIG. 17  is proximate first transverse floor edge  120  when wall portion  200   s - 2  is in the fully unfolded position. Step-down  268  is located between the slot  240  and the outside edge of wall end interlock A  262 . There is also shown in  FIG. 17  a corresponding step-up  269  on the exterior face  227  of floor top interlock  261 . Step-up  269  is an abrupt increase in the thickness of floor top interlock  261 , in the direction moving from the inside edge of floor top interlock  261  toward the outside edge of floor top interlock  261 , which outside edge in the case of the junction depicted in  FIG. 17  is proximate first transverse floor edge  120  when floor portion  300   b  is in the fully unfolded position. Step-up  269  is located between the slot  240  and the inside edge of floor top interlock  261  (distal from first transverse floor edge  120 ). Step-down  268  and step-up  269  are appropriately located to act as a “stop” and insure correct alignment of wall end interlock A  262  with floor top interlock  261  as wall end interlock A  262  slides over floor top interlock  261 . 
     J. Wall End Interlock B ( 263 ), Wall End Interlock A ( 262 ) Sealing System 
       FIG. 18  depicts in exploded form the junction between a wall end interlock B  263  and a wall end interlock A  262 , each shown in cross-section. The particular junction is shown for illustrative purposes between wall portion  200   s - 2  and wall component  200 P, with wall end interlock B  263  positioned on the interior edge of wall component  200 P proximate first transverse edge  108  and wall end interlock A  262  positioned on the vertical edge of wall portion  200   s - 2  proximate first longitudinal edge  106 . In structure  150 , wall portion  200   s - 2  depicted in  FIG. 18  is vertically oriented and wall component  200 P is vertically oriented. 
     In particular, wall end interlock B  263  in  FIG. 18  is an elongate member that has an elongate seal plate  223  with an elongate interior face  226  and an opposing elongate planar exterior face  227 . The exterior face  227  preferably is hard and smooth to provide a good sealing surface. Seal plate  223  has a length the same, or substantially the same, as the height of wall component  200 P when unfolded, so as to cover the interior edge of wall component  200 P proximate to first transverse edge  108 . Seal plate  223  of wall end interlock B  263  has a width the same, or substantially the same, as the width of wall portion  200   s - 2 . In general terms, the design of wall end interlock B  263  is substantially the same as floor top interlock  261  depicted in  FIG. 17 , except wall end interlock B  263  is thinner because it need not accommodate any flooring; for example, wall end interlock B  263  can have a thickness “I” (not shown in  FIG. 18 ) at its interior edge equal to the thickness of an abutting protective layer  218 , such as MgO board. 
     Still referring to  FIG. 18 , an elongate seal slot  240  is defined on the exterior face  227  of wall end interlock B  263 , proximate the interior edge of wall component  200 P positioned adjacent to first longitudinal edge  106 . Seal slot  240  has a length the same, or substantially the same, as the length of wall end interlock B  263 . 
     Wall end interlock B  263  can be secured to the interior edge of wall component  200 P as shown in  FIG. 18  for example by adhesive applied to interior face  226 , or by fasteners, such as screw or nail fasteners, spaced apart along the length of wall end interlock B  263  and driven through the exterior face  227 , or by utilizing a combination of adhesive and fasteners. 
       FIG. 18  additionally shows a wall end interlock A  262  positioned along the depicted vertical edge of wall portion  200   s - 2 . The design of wall end interlock A  262  was previously disclosed in connection with  FIG. 17 . The seal plate  223  of the wall end interlock A  262  shown in  FIG. 18  has a length and width the same, or substantially the same, as the length and width of the depicted vertical edge of wall portion  200   s - 2 , so as to cover the entirety, or substantially the entirety, of that vertical edge of wall portion  200   s - 2 , as shown in in  FIG. 18 . The elongate rectangular key  222  of wall end interlock A  262  shown in  FIG. 18  has a length the same, or substantially the same, as the length of that wall end interlock A  262 . Key  222  is received in a corresponding elongate slot formed in the exterior edge reinforcement positioned on the vertical edge of the wall portion  200   s - 2  to which wall end interlock A  262  is secured. The seal slot  240  of wall end interlock A  262  shown in  FIG. 18  has a length the same, or substantially the same, as the length of that wall end interlock A  262 . In the case where the enclosure component  155 , in this case wall portion  200   s - 2 , utilizes the enclosure component laminate design shown in  FIG. 7 , the locating slots  229  of wall end interlock A  262  shown in  FIG. 18  receive the edge portions of sheet metal layers  205  and  216 , bent down at a ninety degree (90°) angle. 
     Wall end interlock A  262  can be secured to the vertical edge of wall portion  200   s - 2  shown in  FIG. 18  for example by adhesive applied to its interior face  226 , or by fasteners, such as screw or nail fasteners, spaced apart along the length of wall end interlock A  262  and driven through its exterior face  227 , or by utilizing a combination of adhesive and fasteners. 
     In  FIG. 18 , wall end interlock A  262  mates with a wall end interlock B  263 . Prior to mating, a shear seal  260  is placed in the seal slot  240  of wall end interlock A  262 , and a shear seal  260  is placed in the seal slot  240  of wall end interlock B  263 . Each of the shear seals  260  placed in the seals slots  240  of wall end interlock A  262  and a wall end interlock B  263  has the same, or approximately the same, length as the slot  240  in which it is inserted. 
     Mating of wall end interlock A  262  and a wall end interlock B  263  occurs by the vertical edge of wall portion  200   s - 2  depicted in  FIG. 18  swinging toward and across the interior surface of wall component  200 P, as wall portion  200   s - 2  moves from a folded position to an unfolded position. Thus in the arrangement shown in  FIG. 18 , such mating will correspond to a movement of wall portion  200   s - 2  from the top of the figure toward the bottom, with wall end interlock A  262  sliding across wall end interlock B  263  until the fully unfolded position is reached. In that fully unfolded position, the shear seal  260  in wall end interlock A  262 , and particularly its seal surface  257 , will be in pressing contact with the exterior face  227  of wall end interlock B  263 ; and the shear seal  260  in wall end interlock B  263 , and particularly its seal surface  257 , will be in pressing contact with the exterior face  227  of wall end interlock A  262 . Consistent with this movement, the shear seal  260  placed in seal slot  240  of floor top interlock B  263  is preferably oriented so that the free end  258  of its cantilevered seal surface  257  is directed toward the exterior edge of wall end interlock B  263  (toward first transverse edge  108 ), and the shear seal  260  placed in the seal slot  240  of wall end interlock A  262  is preferably oriented so that the free end  258  of its cantilevered seal surface  257  is directed toward the interior edge of wall end interlock A  262  (away from first transverse edge  108 ). 
     To facilitate mating, it is preferred that planar exterior face  227  of wall end interlock B  263  not be parallel to the interior face  226  of wall end interlock B or to the interior face of wall component  200 P, but rather be inclined at an angle γ, as shown in  FIG. 17 , so that seal plate  223  of wall end interlock B  263  becomes progressively thinner moving away from first transverse edge  108 . Likewise, it is preferred that planar exterior face  227  of wall end interlock A  262  be inclined at the same angle γ, as shown in  FIG. 17 , so that seal plate  223  of wall end interlock A  262  becomes progressively thicker moving away from first transverse edge  108 . Accordingly, when vertical edge of wall portion  200   s - 2  swings toward and across the interior surface of wall component  200 P, from a folded position to an unfolded position, the shear seals  260  located in slots  240  of floor end interlock A  262  and wall end interlock B  263  will be compressed by the sliding movement of wall end interlock A  262  to provide two elongate sealing areas between wall component  200 P and wall portion  200   s - 2 . Also to facilitate mating, as previously described a step-down  268  is provided on the exterior face  227  of wall end interlock A  262 . Step-down  268  is an abrupt reduction in the thickness of wall end interlock A  262 , in the direction moving from the inside edge of wall end interlock A  262  toward the outside edge of wall end interlock A  262 , which outside edge in the case of the junction depicted in  FIG. 18  is proximate first transverse edge  108  when wall portion  200   s - 2  is in the fully unfolded position. Step-down  268  is positioned between the slot  240  and the outside edge of wall end interlock A  262  (proximate transverse edge  108 ), as depicted in  FIG. 18 . Also as depicted in  FIG. 18 , a corresponding step-up  269  is provided on the exterior face  227  of wall end interlock B  263 . Step-up  269  is an abrupt increase in thickness of wall end interlock B  263 , in the direction moving from the inside edge of wall end interlock B  263  toward the outside edge of wall end interlock B  263 , which outside edge in the case of the junction depicted in  FIG. 18  is proximate first transverse edge  108 . Step-up  269  is positioned between the slot  240  and the inside edge of wall end interlock B  263  (distal from first transverse edge  108 ). Step-down  268  and step-up  269  are appropriately located to act as a “stop” and insure correct alignment of wall end interlock A  262  with wall end interlock B  263  as wall end interlock A  262  slides across wall end interlock B  263 . 
     K. Closure Boards 
     The two closure boards of these inventions, namely perimeter board  310  and roof skirt board  280 , are described below. 
     Perimeter Board ( 310 ). The exterior edges of floor component  300 , or portions thereof, are optionally provided with a perimeter board  310 . 
       FIG. 19A  depicts in cross section an exemplary positioning of perimeter board  310 . In particular, perimeter board  310  is designed to be positioned against an I-beam end cap  221 , in this instance the I-beam end cap  221  located on an exterior edge of floor portion  300   a.  Perimeter board  310  includes an elongate seal plate  223  with an interior face  226  and an opposing exterior face  227 . Perimeter board  310  has such length as is desired, such as to span the entirety of the exterior edge of floor portion  300   a.  As shown in  FIG. 19A , the width of perimeter board  310  can be sufficient to capture the thickness of the floor component  300   a,  or floor portion thereof against which it is positioned, plus a portion of the abutting wall component  200  or wall component portion. 
     The interior face  226  of perimeter board  310  includes an elongate locating key  264 , which is rectangular in cross section and dimensioned to be received in accessory slot  224  of I-beam end cap  221 . Locating key  264  can be the same length as the perimeter board  310 , or can comprise space apart discrete segments. The interior face  226  of perimeter board  310  in  FIG. 19A  also includes a plurality of elongate clearance slots  266 , rectangular in cross section in the embodiment shown, and having a length the same as, or substantially the same as, the length of perimeter board  310 . Clearance slots  266  are preferably located so as to be positioned over locating grooves  225  of I-beam end cap  221  when locating key  264  is received in accessory slot  224 . When so located, clearance slots  266  provide space for fastener heads driven into locating grooves  225  of I-beam end cap  221  so that perimeter board  310  can be snugly positioned against I-beam end cap  221 . 
     The exterior face  227  of perimeter board  310  depicted in  FIG. 19A  includes two elongate fastener slots  265 , each of which has a dovetail shape in cross section in the embodiment shown, and a length the same as, or substantially the same as, the length of perimeter board  310 . A locating groove  225  is provided in each fastener slot  265 , so as to facilitate the accurate positioning of nails or other fasteners utilized to secure perimeter board  310  to abutting components. 
       FIG. 19B  depicts in cross section the positioning of I-beam end cap  221 , floor top plate  252 , wall end cap  246  and perimeter board  310  relative to each other at a junction between wall component  200 R and floor portion  300   a.  As can be seen, perimeter board  310  masks this junction from external view to achieve a more attractive appearance, as well as providing an additional barrier against the ingress of soil, dust, rain and the like. A resilient strip  267 , such as those shown in  FIG. 19B , can be snapped into each of the fastener slots  265  to cover any nail or fastener heads exposed in those slots. 
     Roof Skirt Board. The exterior edges of roof component  400 , or portions thereof, are optionally provided with a roof skirt board  280 . 
       FIG. 20  depicts in cross section an exemplary positioning of roof skirt board  280 . In particular, roof skirt board  280  is designed to be positioned against an I-beam end cap  221 , in this instance the I-beam end cap  221  located on an exterior edge of roof portion  400   a.  Roof skirt board  280  includes an elongate seal plate  223  with an interior face  226  and an opposing exterior face  227 . Roof skirt board  280  has such length as is desired, such as to span the entirety of the exterior edge of roof portion  400   a.  As shown in  FIG. 20 , the width of roof skirt board  280  can be sufficient to capture the thickness of the roof component  400 , or portion thereof against which it is positioned, plus a portion of the abutting wall component  200  or wall portion. 
     The interior face  226  of roof skirt board  280  includes an elongate cinch key  278 , which is preferably serpentine in cross section and dimensioned to be received in accessory slot  224  of I-beam end cap  221 . Cinch key  278  can be the same length as the perimeter board  310 , or can comprise space apart discrete segments. In turn, the exterior face  227  of roof skirt board  280  includes an elongate fastener slot  265  positioned over cinch key  278 . Fastener slot  265  has a dovetail shape in cross section in the embodiment shown, and a length the same as, or substantially the same as, the length of roof skirt board  280 . An elongate locating groove  225  is provided in the fastener slot  265  of roof skirt board  280 , and provides a visual indication of where to place fasteners during construction. 
     Roof skirt board  280  facilitates the securing of roofing material, such as thermoplastic polyolefin membrane, to wall components  200 . After fully unfolding the roof portions, such roofing material is optionally used to cover the top of roof component  400 . The roofing material extending beyond roof component  400  is then folded down to extend between exterior face  227  of I-beam end cap  221  of roof portion  400   a  shown in  FIG. 20  and interior face  226  of roof skirt board  280 . After the roofing material is so positioned, nails or other fasteners are driven at spaced intervals along locating groove  225 , to press roof skirt board  280  against the roofing material and secure the roofing material in place between roof skirt board  280  and I-beam end cap  221 . Cinch key  278 , if provided with a serpentine or like cross section, provides additional area so as to better capture the roofing material. An elongate resilient strip  267 , such as the one shown in  FIG. 20 , can be snapped into fastener slot  265  to cover any nail or fastener heads exposed in this slot. 
     Enclosure Component Sealing Structure Materials 
     The enclosure component sealing structures described herein can be fabricated from a number of materials, such as wood, aluminum, plastics and the like. It is preferred to fabricate the enclosure component sealing structures from foamed polyvinyl chloride (PVC), particularly Celuka foamed PVC. This material provides a strong, impact and crack-resistant lightweight material with a hard attractive exterior, which, in addition to contributing a sealing function, additionally contributes to the structural rigidity of the enclosure components  155 . 
     Enclosure Component Sealing Structure Exemplary Placements 
     The exploded views in  FIGS. 21A and 21B  of structure  150  depicted in  FIG. 1  provide exemplary placements of the enclosure component sealing structures described herein. For illustrative purposes to better understand some of these exemplary placements, certain of the enclosure component sealing structures shown in  FIG. 21  are shown slightly separated from the enclosure component  155  to which they are fastened. 
     Referring to  FIG. 21A , I-beam end caps  221  can be utilized to seal the horizontal exterior edges of floor portion  300   a  (three placements), floor portion  300   b  (three placements), roof portion  300   a  (three placements), roof portion  300   b  (two placements) and roof portion  300   c  (three placements). Further, as shown in  FIG. 21B  and in detail in  FIG. 12 , the hinged junction between wall portion  200   s - 1  and  200   s - 2  can be sealed by positioning a wall end cap  246  on the vertical edge of wall portion  200   s - 1  and a wall vertical interlock  245  on the vertical edge of wall portion  200   s - 2 . Likewise, the hinged vertical junction between wall portion  200   s - 3  and  200   s - 4  can be sealed as shown in  FIG. 21B  by positioning a wall end cap  246  on the hinged vertical edge of wall portion  200   s - 3  and a wall vertical interlock  245  on the hinged vertical edge of wall portion  200   s - 4 . 
     In addition, as shown in  FIGS. 21A and 21B , and in detail in  FIG. 13 , the horizontal junction between wall component  200 R and roof portion  400   a  can be sealed by positioning a roof bottom plate  255  on the bottom face of roof portion  400   a  overlying wall component  200 R and by positioning a wall end cap  246  on the horizontal edge of wall component  200 R which supports roof portion  400   a.  A like seal arrangement can be used to seal the horizontal junctions between roof portions  400   a,    400   b  and  400   c,  and wall portions  200   s - 1  through  200   s - 4  (unfolded roof portion  400   b  will rest on unfolded wall portion  200   s - 2  and also on a section of wall portion  200   s - 1 , as can be appreciated from  FIG. 3 ), as well as to seal the horizontal junction between roof portion  400   c  and wall component  200 P. The two vertical exterior edges of wall component  200 R can each be sealed by positioning on each of them a wall end cap  246 . 
     In a comparable manner, as shown in  FIGS. 21A, 21B  and in detail in  FIG. 15 , the horizontal junction between wall component  200 R and floor portion  300   a  can be sealed by positioning a wall end cap  246  on the horizontal edge of wall component  200 R resting on floor portion  300   a  and by positioning on the top face of floor portion  300   a  underlying wall component  200 R a floor top plate  252 . A like seal arrangement can be used to seal the horizontal junctions between floor portion  300   b  and wall component  200 P, and between floor portion  300   a  and wall portions  200   s - 1  and  200   s - 3 , up to the point where wall portion  200   s - 1  meets wall portion  200   s - 2 , and up to the point where wall portion  200   s - 3  meets wall portion  200   s - 4 . The two vertical exterior edges of wall component  200 P can be sealed by positioning on each of them a wall end cap  246 . 
     Furthermore, the hinged horizontal junction between roof portion  400   b  and roof portion  400   c,  as shown in  FIG. 21A  and in detail in  FIG. 14 , can be sealed by positioning an I-beam interlock A  250  on interior edge  412   c  of roof portion  400   c,  and an I-beam interlock B  251  on first interior edge  412   b  of roof portion  400   b.  Similarly, the hinged horizontal junction between roof portion  400   a  and roof portion  400   b  shown in  FIG. 21A  can be sealed by positioning an I-beam interlock A  250  on second interior edge  412   b  of roof portion  400   b,  and an I-beam interlock B  251  on interior edge  412   a  of roof portion  400   a.  In like manner, the hinged horizontal junction between floor portion  300   a  and floor portion  300   b  can be sealed by positioning an I-beam interlock A  250  on the interior edge  301   b  of floor portion  300   b  and an I-beam interlock B  251  on the interior edge  301   a  of floor portion  300   a.    
     Referring now to  FIGS. 21A, 21B  and in detail to  FIG. 17 , the horizontal junction between wall portion  200   s - 2  and floor portions  300   a,    300   b  can be sealed by positioning a wall end interlock A  262  on the bottom edge of wall portion  200   s - 2  and a floor top interlock  261  on the regions of the upper face of floor portions  300   a  and  300   b  underlying wall portion  200   s - 2  when wall portion  200   s - 2  is in its fully unfolded position. The horizontal junction between wall portion  200   s - 4  and floor portions  300   a  and  300   b  when wall portion  200   s - 4  in its fully unfolded position can be sealed similarly. 
     Finally, referring to  FIG. 21B  and in detail to  FIG. 18 , the vertical junction between wall portion  200   s - 2  and wall component  200 P can be sealed by positioning a wall end interlock A  262  on the vertical edge of wall portion  200   s - 2  that is adjacent to wall component  200 P when both wall portion  200   s - 2  and wall component  200 P are in their fully unfolded positions, and by positioning a wall end interlock B  263  on the region of the interior face of wall component  200 P that is adjacent wall portion  200   s - 2  when both wall portion  200   s - 2  and wall component  200 P are in their fully unfolded positions. The vertical junction between wall portion  200   s - 4  and wall component  200 P can be sealed in like manner 
     Enclosure Component Manufacture 
     A. General Description 
       FIG. 22  depicts a facility  10  for fabricating the enclosure components  155 . The facility comprises a conveyor table  50 , a press table  51 , and in the embodiment shown in  FIG. 22 , four material turntables  52 A,  52 B,  52 C and  52 D and four robotic assemblers  54 A,  54 B,  54 C and  54 D. There is also an adhesive spray gantry  55  straddling the conveyor table  50 . Whether partitioned or not, all of the enclosure components  155 —wall components  200 , floor components  300  and roof components  400 —can be formed on the same facility  10 . 
     Conveyor table  50  is provided with a plurality of cylindrical rollers to facilitate movement of work pieces from the assembly area  56  onto the press table  51 . The enclosure components  155  are built up, layer upon layer, in the assembly area  56 , and then moved into the press table  51 . The movement of materials from turntables  52 A,  52 B,  52 C and  52 D onto conveyor table  50  can be done manually, by manufacturing personnel. Alternatively, robotic assemblers, such as robotic assemblers  54 A,  54 B,  54 C and  54 D depicted in  FIGS. 22 and 23 , can be employed to carry out some or all of such movement, either under the control of manufacturing personnel, or under the control of an appropriately-programmed computer controller. 
     Press table  51  preferably employs a vacuum bag system to press together the layers forming enclosure components  155 . Spray gantry  55  is movable over conveyor table  50  between a first position proximate to press table  51  and a second position distal from press table  51 . Spray gantry  55  is provided with a number of downward-directed spray heads for spraying adhesive, such as polyurethane based construction adhesive, onto the work pieces, as directed. 
     The facility  10  is designed to fabricate two enclosure components  155  simultaneously. Thus robotic assemblers  54 A and  54 B are positioned as opposed pairs with conveyor table  50  between them, as shown in  FIG. 22 , and are used to move sheets and panels from turntables  52 A and  52 B, respectively, to appropriate locations on conveyor table  50  to form a first enclosure component  155 . Likewise, robotic assemblers  54 C and  54 D are positioned as opposed pairs with conveyor table  50  between them, as shown in  FIG. 5 , and are used to move sheets and panels from turntables  52 C and  52 D, respectively, to appropriate locations on conveyor table  50  to form a second enclosure component  155 . Looking down at turntables  52 A- 52 D in  FIG. 22  and assuming them to have the face of a clock (with the twelve o′clock position being closest to press table  51 ), robotic assemblers  54 A and  54 C are adapted to move sheets and panels from the access positions of turntables  52 A and  52 C respectively (proximate the nine o′clock position on turntables  52 A and  52 C), to conveyor table  50 . Correspondingly, robotic assemblers  54 B and  54 D are adapted to move sheets and panels from the access positions of turntables  52 B and  52 D respectively (proximate the three o′clock position on each of turntables  52 B and  52 D), to conveyor table  50 . 
     In the facility  10  shown in  FIG. 22 , the access positions on turntables  52 A- 52 D are made sufficiently large so as to be able to position two or more sheets and/or panels adjacent to each other at those access positions. This permits robotic assemblers  54 A- 54 D to have access to two or more sheets and/or panels that are not stacked, one or top of another, without the need to rotate further the turntables  52 A- 52 D. Further, the stacks need not be homogenous, but can be mixed stacks comprising sheets and panels appropriately interspersed for more efficient assembly; i.e., a stack may include both foam panels and metal sheets. In addition, the sheets and/or panels in a stack may have different sizes, and a stack may contain two or more adjacent sheets and/or stacks overlying or underlying a single sheet and/or panel, depending upon the dimensions of the sheets and/or panels and the sequence of fabrication. 
     As directed, turntables  52 A- 52 D are rotated to bring sheets and panels to their respective access positions. In the manufacturing sequence described below, each turntable is rotated counterclockwise ninety (90°) degrees, as sheets and/or panels are removed from it, to bring into the access position the next appropriate sheets and/or panels. The rotation of the turntables  52 A- 52 D can be manual, or power-driven, and in the latter case can be conducted using an appropriately-programmed computer controller, which can also control the operation of robotic assemblers  54 A- 54 D and spray gantry  55 . 
     For exemplary purposes, the sequence for fabricating two wall components  200 , specifically wall component  200 P, is described in connection with  FIGS. 23A-23J . However, it should be understood that the fabrication sequence described below applies equally to the fabrication of floor components  300  and roof components  400 , and to the fabrication of partitioned portions thereof. For the illustrated wall components  200 , those sheets and panels in which there will be desired apertures, such as door apertures  202  and window apertures  204 , are pre-cut, where appropriate, with the desired apertures, and then placed on the turntables  52 B and  52 D, which are located on a first side of conveyor table  50 . The sheets and panels of this wall component  200  in which there will not be formed any such desired apertures are correspondingly placed on the turntables  52 A and  52 C, which are located on the second side of conveyor table  50 . As an alternative, the formation of any door and window apertures  202 ,  204  can be deferred until after the fabrication steps described herein. 
     In general, the manufacturing sequence comprises placing on conveyor table  50  the metal sheets  206  forming the sheet metal layer  205  of the first structural layer  210 , followed by the foam panels  214  of foam panel layer  213 , the metal sheets  217  forming the sheet metal layer  216  of second structural layer  215 , and lastly the building panels  219  of protective layer  218 , in that order. In the two exemplary wall components  200  shown being fabricated in  FIGS. 23A-23J , each of the layers of the wall component  200  (first structural layer  210 , foam panel layer  213 , second structural layer  215  and protective layer  218 ) is made from five sheets or panels. Accordingly, first structural layer  210  is made from five metal sheets  206  (consecutively denominated  206 - 1  to  206 - 5 ) that are positioned on conveyor table  50  adjacent each other; foam panel layer  213  is made from five foam panels  214  (consecutively denominated  214 - 1  to  214 - 5 ) that are positioned on conveyor table  50  adjacent each other; second structural layer  215  is made from five metal sheets  217  (consecutively denominated  217 - 1  to  217 - 5 ) that are positioned on conveyor table  50  adjacent each other; and protective layer  218  is made from five building panels  219  (consecutively denominated  219 - 1  to  219 - 5 ) that are positioned on conveyor table  50  adjacent each other. 
     For the exemplary wall components  200  fabricated in the manner shown in  FIGS. 23A-23J , even-numbered sheets and panels (e.g.,  206 - 2 ,  206 - 4 ,  214 - 2 ,  214 - 4 , etc.) have apertures, specifically window apertures  204 , and odd-numbered sheets and panels (e.g.,  206 - 1 ,  206 - 3 ,  214 - 1 ,  214 - 3 , etc.) do not have any such apertures. Although for ease of understanding the assembly sequence, the sheets and panels in  FIGS. 22 and 23  are depicted as the same size, with one placed directly upon the other, the sheets and panels can be sized and/or placed so that the seams between adjacent sheets or panels are offset from the seams of overlying or underlying sheets or panels, so as to yield an overlapping relationship between the sheets and panels of different layers, with the goal of increasing the strength of the enclosure components  155  being fabricated, in this case wall components  200 . 
     B. Sheet/Panel Design for Manufacturing 
     For enclosure components  155  having the construction disclosed in reference to  FIG. 7 , the sheets forming each of first structural layer  210  and second structural layer  215  can be entirely flat and juxtaposed in a simple abutting relationship, as shown in  FIGS. 23A-23J  (these figures are discussed below in Section C, “Sheet/Panel Manufacturing Sequence”). Optionally, metal sheets  206  and  217  can be provided with edge structures that facilitate placement of sheets and panels during manufacture. 
     In this regard,  FIG. 8  depicts the five metal sheets  206 - 1  through  206 - 5  comprising sheet metal layer  205  of first structural layer  210  of a wall component  200  being fabricated in facility  10 . The particular wall component to be fabricated from sheets  206 - 1  to  206 - 5  shown in  FIGS. 23A-23B  is wall component  200 P, which will be positioned at a first longitudinal edge  106  of a structure  150 . For better understanding, the longitudinal direction in  FIG. 8  is indicated by arrow “L”, and the vertical direction in  FIG. 8  is indicated by arrow “V”. The orientation of sheets  206 - 1  to  206 - 5  relative to longitudinal floor edge  117  and longitudinal roof edge  406  is additionally shown in the  FIG. 8 . 
     The present invention provides for two types of edge structures for the metal sheets utilized to fabricate enclosure components  155 , namely exterior edge structures and interior edge structures. Both exterior and interior edge structures are described below with reference to metal sheets  206  of the sheet metal layer  205  forming first structural layer  210 , although it should be understood that the exterior and interior edge structures described below are preferably also provided at comparable locations on metal sheets  217  of sheet metal layer  216  forming second structural layer  215 . 
     An exterior edge structure for the metal sheets  206  of sheet metal layer  205  is shown in profile in  FIG. 9A , and comprises an elongate planar edge portion  207  joined to metal sheet  206  by an edge bend  271 . Edge portion  207  extends away from the interior face  208  of metal sheet  206  at a negative ninety degrees (−90°) angle bend (a negative angle bend is in the counter-clockwise direction in  FIG. 9A ), and is shown oriented upward in  FIG. 8  and downward in  FIG. 9A . Edge portion  207  is received in locating slots  229  provided in edge component sealing structures. An example of this is shown in  FIG. 24A , which depicts the edge portion  207  of metal sheet  206  received in a locating slot  229  of an I-beam end cap  221  positioned on an exterior edge of roof portion  400   a.  In  FIG. 8 , edge portions  207  are provided along the bottom and top exterior longitudinal edges of metal sheets  206 - 1  to  206 - 5  (the edges proximate to longitudinal floor edge  117  and longitudinal roof edge  406  respectively). In addition, edge portions  207  are shown in  FIG. 8  as provided along the exterior vertical edges of metal sheets  206 - 1  and  206 - 5 . It should also be understood that edge portions  207  can be provided at comparable locations along exterior edges of the five metal sheets  217 - 1  through  217 - 5 , and in general along comparable exterior edges of any metal sheets of each other enclosure component  155  of multi-layered, laminate design in accordance with  FIG. 7 . Thus for example  FIG. 24A  also depicts the edge portion  207  of metal sheet  217  of roof portion  400   a  received in a locating slot  229  of an I-beam end cap  221  positioned on an exterior edge of roof portion  400   a.    
     Interior edge structures for the metal sheets  206  of sheet metal layer  205  are shown in profile in  FIG. 9B and 9C . There are two types of interior edge structures, an insertion section and a receiver section. For any two adjacent interior edges of metal sheets  206 , a first interior edge can be provided with an insertion section of a specific design and the second interior edge can be provided with a receiver section of a specific design paired to receive the insertion section of the first interior edge. When so paired, the interior edge structures are the interface between the interior edges of two adjacent metal sheets  206 , and accordingly, such paired interior edge structures are generically referenced in this disclosure as an interior edge interface  290 . 
       FIG. 9B  shows in profile a first embodiment of an interior edge interface  290 , denominated  290 - 1 , with reference to the adjacent edges of metal sheets  206 - 1  and  206 - 2 . It should however be understood that interior edge interface  290 - 1  can also be provided at the adjacent edges of metal sheets  206 - 2  and  206 - 3 ,  206 - 3  and  206 - 4 , and  206 - 4  and  206 - 5 , as well as at comparable adjacent edges of metal sheets  217 - 1  and  217 - 2 ,  217 - 2  and  217 - 3 ,  217 - 3  and  217 - 4 , and  217 - 4  and  217 - 5  and comparable adjacent edges of metal sheets of each other enclosure component  155  of laminate design in accordance with  FIG. 7 . Interior edge interface  290 - 1  comprises a receiver section  272  and an insertion section  282 , as described further below. 
     In particular, receiver section  272  of interior edge interface  290 - 1  comprises a planar elongate first receiver region  273 , a planar elongate second receiver region  274  and a planar elongate third receiver region  275 . First receiver region  273  is shown joined in  FIG. 9B  to metal sheet  206 - 1  by an elongate edge bend  271 . In  FIG. 9B , edge bend  271  is a positive ninety degree (+90°) angle bend (a positive angle bend is in the clockwise direction in  FIGS. 9A through 9C ), so that first receiver region  273  extends away from the interior face  208  of metal sheet  206 - 1  in a perpendicular direction. 
     The portion of first receiver region  273  of interior edge interface  290 - 1  which is distal from edge bend  271  is joined by an elongate first bend  276  to a second receiver region  274 . First bend  276  is at least a negative one hundred thirty five degree (−135°) obtuse angle bend, such as a negative one hundred eighty degree (−180°) angle bend, so that second receiver region  274  extends toward the interior face  208  of metal sheet  206 - 1 , such as in a perpendicular direction. (In this description of edge interfaces, a linear or planar feature “extends toward” another linear or planar feature, or “extends away” from another linear or planar feature, if in the event that the two features were extended to intersect, the angle of intersection would be in the range of from greater than forty five degrees (45°) up to and including ninety degrees (90°), the perpendicular direction.) 
     The portion of second receiver region  274  of interior edge interface  290 - 1 , which is distal from first bend  276 , is joined by an elongate second bend  277  to third receiver region  275 . Second bend  277  is at least a negative one hundred thirty five degree (−135°) bend, such as a negative a one hundred eighty degree (−180°) angle bend, such that third insertion region  275  extends away from the interior face  208  of metal sheet  206 - 1 , such as in a perpendicular direction. The portion of third insertion region distal from second bend  277  terminates at a free edge  279 . The width of first insertion region  273  (the vertical direction in  FIG. 9B ) is larger than the width of second insertion region  274 , for example being approximately twice the width, and the width of third receiver region  275  is smaller than the width of second receiver region  274 , such as to define a gap between free edge  279  and first bend  276 . 
       FIG. 9B  additionally shows first insertion section  282  of interior edge interface  290 - 1 . That first insertion region  282  comprises a planar elongate first insertion region  283 , a planar elongate second insertion region  284  and optionally a planar elongate third insertion region  285 . First insertion region  283  is joined to metal sheet  206 - 2  by an elongate edge bend  271 . Edge bend  271  at this junction is a negative ninety degree (−90°) angle bend, so that first insertion region  283  extends away from the interior face  208  of metal sheet  206  in a perpendicular direction. The portion of first insertion region  283  distal from edge bend  271  is joined by an elongate first bend  286  to second insertion region  284 . First bend  286  is at least a negative one hundred thirty five degree (−135°) obtuse angle bend, such as a negative one hundred eighty degree (−180°) angle bend, so that second insertion region  284  extends toward the interior face  208  of metal sheet  206 - 2 , such as in a perpendicular direction. 
     The portion of second insertion region  284  of interior edge interface  290 - 1 , which is distal from first bend  286 , is optionally joined by an elongate second bend  287  to third insertion region  285 . Second bend  287  is at least a negative forty five degree (−45°) angle bend, such as a negative ninety degree (−90°) angle bend, such that optional third insertion region  285  does not extend toward the interior face  208  of metal sheet  206 - 2 , but rather such that optional third insertion region  285  extends away from second insertion region  284  toward first insertion region  283 . The portion of optional third insertion region  285  distal from second bend  287  terminates at a free edge  279 . 
     In the embodiment of interior edge interface  290 - 1  shown in  FIG. 9B , the length of first insertion region  283  (the vertical direction in  FIG. 9B ) is larger than the length of second insertion region  284 , and the vertical distance between the bottom of first bend  286  and free edge  279  of third insertion region  285  should permit second and third insertion regions  284 ,  285  to be press-fit into the gap between free edge  279  and first bend  276  of receiver section  272 . In this regard, the curvature of first bend  276  should be sufficient to permit insertion of second and third insertion regions  284 ,  285  into the gap between free edge  279  and first bend  276  of receiver section  272 . To facilitate a smooth transition between metal sheet  206 - 1  and  206 - 2  when utilizing interior edge interface  290 - 1 , the width of first insertion region  283  (the horizontal direction in  FIG. 9B ) should be equal to the width of first receiver region  273 , or approximately so. 
     In the event that optional third insertion region  285  of interior edge interface  290 - 1  is not utilized, then second bend  287  terminates at free edge  279 . As in the case where a third insertion region is used, second bend  287  at the location of free edge  279  is at least a negative forty five degree (−45°) angle bend, such as a negative ninety degree (−90°) angle bend. The bend angle of second bend  287  should be such that a line tangent to second bend  287  at free edge  279  does not extend toward the interior face  208  of metal sheet  206 , but rather extends toward first insertion region  283 . In this alternative, the vertical distance between the bottom of first bend  286  and free edge  279  of second bend  287  should permit second insertion region  284  and second bend  287  to be press-fit into the gap between free edge  279  and first bend  276  of receiver section  272 . 
       FIG. 9C  shows in profile a second embodiment of an interior edge interface  290 , denominated  290 - 2 , with reference to the adjacent edges of metal sheets  206 - 1  and  206 - 2 . It should however be understood that interior edge interface  290 - 2  can also be provided at the adjacent edges of metal sheets  206 - 2  and  206 - 3 ,  206 - 3  and  206 - 4 , and  206 - 4  and  206 - 5 , as well as at comparable adjacent edges of metal sheets  217 - 1  and  217 - 2 ,  217 - 2  and  217 - 3 ,  217 - 3  and  217 - 4 , and  217 - 4  and  217 - 5  and comparable adjacent edges of metal sheets of each other enclosure component  155  of laminate design in accordance with  FIG. 7 . Interior edge interface  290 - 2  comprises a receiver section  281  and an insertion section  291 , as described further below. 
     In particular, receiver section  281  of interior edge interface  290 - 2  comprises a planar elongate first receiver region  273  and a planar elongate second receiver region  274 . First receiver region  273  is shown joined in  FIG. 9C  to metal sheet  206 - 1  by an elongate edge bend  271 . In  FIG. 9C , edge bend  271  is a positive ninety degree (+90°) angle bend, so that first receiver region  273  extends away from the interior face  208  of metal sheet  206 - 1  in a perpendicular direction. 
     The portion of first receiver region  273  of interior edge interface  290 - 2 , which is distal from edge bend  271 , is joined by an elongate first bend  276  to second receiver region  274 . First bend  276  is at least a negative one hundred thirty five degree (−135°) obtuse angle bend, such as a negative one hundred eighty degree (−180°) angle bend, so that second receiver region  274  extends toward the interior face  208  of metal sheet  206 - 1 , such as in a perpendicular direction. The portion of second receiver region  274  distal from first bend  276  terminates at a free edge  279 . 
       FIG. 9C  additionally shows first insertion section  291  of interior edge interface  290 - 2 . That first insertion section  291  comprises a planar elongate first insertion region  283  and a planar elongate second insertion region  284 . First insertion region  283  is joined to metal sheet  206 - 2  by an elongate edge bend  271 . In  FIG. 9C , edge bend  271  is a negative ninety degree (−90°) angle bend, so that first insertion region  283  extends away from the interior face  208  of metal sheet  206  in a perpendicular direction. 
     The portion of first insertion region  283  of interior edge interface  290 - 2 , which is distal from edge bend  271 , is joined by an elongate first bend  286  to second insertion region  284 . First bend  286  is at least a negative one hundred thirty five degree (−135°) bend, such as a one hundred eighty degree (180°) angle bend, such that second insertion region  284  extends toward the interior face  208  of metal sheet  206 , such as in a perpendicular direction. The portion of second insertion region  284  of interior edge interface  290 - 2 , which is distal from first bend  286  terminates at a free edge  279 . 
     In interior edge interface  290 - 2  shown in  FIG. 9C , the length of first insertion region  283  (the vertical direction in  FIG. 9C ) is shown as larger than the length of second insertion region  284 ; for example, first insertion region  283  can be at least double the length of second insertion region  284 . Also, the length of first receiver region  273  is shown as larger than the length of second receiver region  274 ; for example, first receiver region  273  can be at least double the length of second receiver region  274 . In this regard, the curvature of first bend  276  should be such as to permit insertion of first and second insertion regions  283 ,  284  between first and second receiver regions  273 ,  274 . To facilitate a smooth transition between metal sheet  206 - 1  and  206 - 2  when utilizing interior edge interface  290 - 2 , the width of first insertion region  283  should be equal to the width of first receiver region  273 , or approximately so.

     Table 1 also applies to the wall assembly  200  fabricated from the sheets and panels positioned on turntables  52 C and  52 D; i.e., the column in Table 1 for turntable  52 A also applies to turntable  52 C, and the column in Table 1 for turntable  52 B also applies to turntable  52 D. 
     Step 1: First Structural Layer Formation.  FIG. 23A  depicts robotic assemblers  54 A- 54 D moving metal sheets  206  from their access positions on turntables  52 A- 52 D to pre-selected locations in assembly area  56  (shown in  FIG. 22 ) on conveyor table  50 . In accordance with the movement sequence described in Table 1, robotic assemblers  54 A- 54 D move metal sheets  206 - 1  through  206 - 5  in sequence to conveyor table  50  until all sheets forming first structural layer  210  of the two exemplary wall components  200  have been appropriately placed in assembly area  56  on conveyor table  50 . 
     If exterior or interior edge structures are provided on metal sheets  206 - 1  to  206 - 5 , then those structures should be oriented to face upward when placed on conveyor table  50 , as shown in  FIG. 8 , and the receiving section of each metal sheet  206 - 1  through  206 - 4  should be oriented to receive the insertion section of the adjacent sheet  206 - 2  through  206 - 5  respectively. The use of interior edge interfaces  290  facilitates the accurate placement of the metal sheets  206 - 1  through  206 - 5  adjacent to each other. At the particular point in manufacturing shown in  FIG. 23A , robotic assembler  54 A has already removed metal sheet  206 - 1  from its access position on turntable  52 A and placed it at a preselected location in assembly area  56  on conveyor table  50 , and turntable  52 A has been rotated counterclockwise ninety degrees (90°) to bring into the access position the next sheet or panel for placement onto conveyor table  50 , in this case metal sheet  206 - 3 . Likewise at the particular point in manufacturing shown in  FIG. 23A , robotic assembler  54 B has already removed a metal sheet  206 - 2  from its access position on turntable  52 B and placed it at a preselected location in assembly area  56  on conveyor table  50 , adjacent metal sheet  206 - 1 . 
     Step 2: First Adhesive Application.  FIG. 23B  depicts all metal sheets  206 - 1  to  206 - 5  forming first structural layer  210  of the exemplary two wall components  200  properly placed in assembly area  56  on conveyor table  50 , after having been moved there by robotic assemblers  54 A- 54 D. The exposed faces of sheets  206  are then coated with adhesive. This step is performed by spray gantry  55 , which moves over the exposed faces of sheets  206 , in the direction “L”, as indicated by the arrow in  FIG. 23C , from a position proximate press table  51  to a position distal from press table  51 , while spraying adhesive on the exposed faces so as to coat substantially the entirety of the exposed faces. Optionally, gantry  55  can remain distal from press table  51  after completing the adhesive spray, as shown in  FIG. 23D , until utilized in a subsequent manufacturing step. 
     Step 3: Foam Panel Layer Formation.  FIG. 23D  depicts robotic assemblers  54 A- 54 D moving foam panels  214 - 1  and  214 - 2  from their access positions on turntables  52 A- 52 D to preselected locations in assembly area  56  (shown in  FIG. 22 ), overlying the adhesive-coated sheets  206  positioned on conveyor table  50 . In like manner, and in accordance with the movement sequence described in Table 1, further foam panels  214  are moved in a preselected sequence to conveyor table  50  until all panels forming foam panel layer  213  of the two exemplary wall components  200  are in their appropriate position on conveyor table  50 ; thus  FIG. 23E  depicts the final foam panel  214 - 5  forming foam panel layers  210  of the exemplary two wall components  200  being placed in assembly area  56  on conveyor table  50  by robotic assemblers  54 A and  54 C. 
     Foam panels  214 - 1  through  214 - 5  preferably are pre-cut with channels  209  at appropriate locations so as to receive any interior edge structures on the metal sheets  206 - 1  to  206 - 5 , which extend beyond the plane of metal sheets  206 - 1  to  206 - 5 , so that the foam panels lie flush on metal sheets  206 - 1  to  206 - 5 . Foam panels  214 - 1  through  214 - 5  preferably are also pre-cut with channels  209  at appropriate locations so as to receive any interior edge structures on metal sheets  217 - 1  to  217 - 5 , which are to be positioned above the foam panels in Step 5 below, so that metal sheets  217 - 1  to  217 - 5  will lie flush on the foam panels. Comparable channels  209  preferably are pre-cut in the foam panels utilized for each other enclosure component  155  of laminate design in accordance with  FIG. 7  to accommodate such interior edge structures as may be utilized between the interior edges of adjacent metal sheets.  FIG. 24B  is an example of an interior edge interface  290 - 2  between two adjacent representative metal sheets, denominated  206 - x  and  206 - y,  as it is received in a channel  209 . 
     Following placement of foam panels  214 - 1  through  214 - 5  on conveyor table  50  to form foam panel layer  213 , any exterior edge reinforcement and sealing structures to be utilized can be positioned in place. For example, wall end caps  246  of suitable length can be positioned and fastened to floor plate  220 , ceiling plate  240  and end pieces  270 , and these subassemblies can then be placed on conveyor table  50 , with their locating slots  229  receiving the edge portions  207  located along the longitudinal and vertical edges of metal sheets  206 - 1  and  206 - 5 . 
     Step 4: Second Adhesive Application. Following Step 3, the exposed faces of foam panels  214  are coated with adhesive. This step is performed by spray gantry  55 , in a manner similar to the depiction in  FIG. 23C . In particular, spray gantry  55  moves over the exposed faces of foam panels  214 , while spraying adhesive on the exposed faces so as to coat substantially the entirety of the exposed faces. In the embodiment depicted in  FIGS. 23A-23J , spray gantry  55  applies adhesive to foam panels  214  by moving from a position distal from press table  51  to a position proximate press table  51 . 
     Step 5: Second Structural Layer Formation.  FIG. 23F  depicts robotic assemblers  54 A- 54 D moving metal sheets  217 - 1  and  217 - 2  from their access positions on turntables  52 A- 52 D to preselected locations in assembly area  56  (shown in  FIG. 22 ), overlying the adhesive-coated foam panels  24  previously formed on conveyor table  50 . In like manner, and in accordance with the movement sequence described in Table 1, further sheets  217  are moved in a preselected sequence to conveyor table  50  until all sheets forming second structural layer  215  of the two exemplary wall components  200  are in their appropriate positions on conveyor table  50 . 
     When placed upon the adhesive-coated foam panels  214  positioned on conveyor table  50 , any and all exterior and interior edge structures on metal sheets  217 - 1  to  217 - 5  should face downward, not upward as shown in  FIG. 8 , and the receiving section of each metal sheet  217 - 1  through  217 - 4  should be oriented to receive the insertion section of the adjacent sheet  217 - 2  through  217 - 5  respectively. The use of interior edge interfaces  290  facilitates the accurate placement of the metal sheets  217 - 1  through  217 - 5  adjacent to each other. Metal sheets  217 - 1  through  217 - 5 , when placed upon the adhesive-coated foam panels  214 , should be positioned so that their edge portions  207  are received in the locating slots  229  of the wall end caps  246  previously secured in place, and as indicated above, should be positioned so that any and all interior edge structures on metal sheets  217 - 1  to  217 - 5  are received in appropriately located, pre-cut channels  209  in foam panels  214 - 1  through  214 - 5 , so that sheet metal layer  216  lies flush on foam panel layer  213 . 
     Step 6: Third Adhesive Application.  FIG. 23G  depicts the final metal sheet  217 - 5  forming second structural layer  215  of the exemplary two wall components  200  being placed in assembly area  56  on conveyor table  50  by robotic assembler  54 A. After that placement, the exposed faces of metal sheets  217  are coated with adhesive. This step is performed by spray gantry  55 , in a manner similar to the depiction in  FIG. 23C . In particular, spray gantry  55  moves over the exposed faces of metal panels  217 , while spraying adhesive on the exposed faces so as to coat substantially the entirety of the exposed faces. In the embodiment depicted in  FIGS. 23A-23J , spray gantry  55  applies adhesive to metal sheets  217  by moving from a position proximate press table  51  to a position distal from press table  51 . Optionally, gantry  55  can remain distal to press table  51  after completing the adhesive spray, as shown in  FIG. 23F , until utilized in a subsequent manufacturing step, or can be returned to a position proximate press table  51 . 
     Step 7: Protective Layer Formation.  FIG. 23H  depicts robotic assemblers  54 A- 54 D moving building panels  219 - 1  and  219 - 2  from their access positions on turntables  52 A- 52 D to preselected locations in assembly area  56  (shown in  FIG. 5 ), overlying the adhesive-coated metal sheets  217  previously formed on conveyor table  50 . In like manner, and in accordance with the movement sequence described in Table 1, further building panels  219  are moved in a preselected sequence to conveyor table  50  until all sheets forming protective layer  218  of the two exemplary wall components  200  are in their appropriate positions on conveyor table  50 . 
     During this step 7, a wall end interlock B  263  of suitable length can be positioned on the interior edge of the wall component  200  (specifically wall component  200 P), abutting protective layer  218  and proximate what will be the first transverse edge  108  of structure  150 , and a wall end interlock B  263  of suitable length can be positioned on the interior edge of the wall component  200  (specifically wall component  200 P), abutting protective layer  218  and proximate what will be the second transverse edge  110  of structure  150 . 
     Step 8: Laminate Press. After all building panels  219  forming protective layer  218  of the two exemplary wall components  200  are in their assembly position on conveyor table  50 , each work piece is moved from conveyor table  50  into press table  51 , as exemplified by  FIG. 23J . Within press table  51 , the work pieces are sandwiched between flexible sheets and a vacuum is applied between the sheets, which causes the panels and sheets of the work piece to be pressed together under atmospheric pressure to finish the laminate structure. In the embodiment shown, the press table is sized to accommodate both work pieces at the same time. 
     After the laminate press step (Step 8), the wall components  200  are removed from press table  51  and then subject to any desired finishing steps to complete the wall components  200 . 
     Optionally, in appropriate situations certain of the foregoing manufacturing sequence steps can be initiated prior to completion of the previous manufacturing sequence step, such that the manufacturing steps are conducted at least in part in an overlapping manner For example, the foam panel layer formation performed in step 3 can be initiated prior to completion of the adhesive application performed in step 2. Thus as can be seen in  FIG. 23C , robotic assemblers  54 A- 54 D are depicted as already starting to engage the foam panels  214  needed for foam panel layer formation, while spray gantry  55  is still spraying adhesive on the exposed faces of sheets  206 . Overlapping the manufacturing sequence steps in this manner advantageously reduces overall manufacturing time. 
     Enclosure Component Relationships and Assembly for Transport 
     For ease of transport and maximum design flexibility, it is preferred that there be a specific dimensional relationship among enclosure components  155 . 
       FIG. 2  shows a top schematic view of structure  150  shown in  FIG. 1 , and includes a geometrical orthogonal grid for clarity of explaining the preferred dimensional relationships among its enclosure components  155 . The basic length used for dimensioning is indicated as “E” in  FIG. 2 ; the orthogonal grid overlaid in  FIG. 2  is 8E long and 8E wide; notably, the entire structure  150 , including perimeter boards  310 , preferably is bounded by this 8E by 8E orthogonal grid. 
     Roof portions  400   a,    400   b  and  400   c  each can be identically dimensioned in the transverse direction. Alternatively, referring to  FIG. 3 , roof portion  400   c  (which is stacked upon roof portions  400   a  and  400   b  when roof portions  400   b,    400   c  are fully folded) can be dimensioned to be larger than either of roof portion  400   a  and roof portion  400   b  in the transverse direction for example, by ten to fifteen percent, or by at least the aggregate thickness of roof components  400   a  and  400   b.  This transverse direction dimensional increase is to reduce the chances of binding during the unfolding of roof portions  400   b,    400   c.  In addition, as described in U.S. Nonprovisional patent application Ser. No. 16/786,315, entitled “Equipment and Methods for Erecting a Transportable Foldable Building Structure,” and filed on Feb. 10, 2020, friction-reducing components can be used to facilitate unfolding roof component  400 , such as by positioning a first wheel caster at the leading edge of roof portion  400   c  proximate to the corner of roof portion  400   c  that is supported by wall portion  200   s - 2  as roof portion  400   c  is deployed, and by positioning a second similar wheel caster at the leading edge of roof portion  400   c  proximate to the corner of roof portion  400   c  that is supported by wall portion  200   s - 4  as roof portion  400   c  is deployed. In such a case, roof portion  400   c  can be dimensioned larger than either of roof portions  400   a  and  400   b  in the transverse direction by at least the aggregate thickness of roof components  400   a  and  400   b,  less the length of the first or second wheel caster. 
     In  FIG. 2 , the four wall components  200  are each approximately 8E long, and each of roof portions  400   a  and  400   b  is approximately 8E long and 2.5E wide. Roof portion  400   c  is approximately 8E long and 2.9E wide. In  FIGS. 2 and 3 , each of floor components  300   a  and  300   b  is 8H long; whereas floor component  300   a  is just over 3E wide and floor component  300   b  is just under 5E wide. 
     The shipping module  100  shown edge-on in  FIG. 3  includes a fixed space portion  102  defined by roof component  400   a,  floor component  300   a,  wall component  200 R, wall portion  200   s - 1  and wall portion  200   s - 3 . As shown in  FIG. 2 , second wall portion  200   s - 2  is folded inward and positioned generally against fixed space portion  102 , and fourth wall portion  200   s - 4  is folded inward and positioned generally against second wall portion  200   s - 2  (wall portions  200   s - 2  and  200   s - 4  are respectively identified in  FIG. 2  as portions  200   s - 2   f  and  200   s - 4   f  when so folded and positioned). The three roof components  400   a,    400   b  and  400   c  are shown unfolded in  FIG. 1  and shown folded (stacked) in  FIG. 3 , with roof component  400   b  stacked on top of roof component  400   a,  and roof component  400   c  stacked on top of the roof component  400   b.  Wall component  200 P, shown in  FIGS. 2 and 3 , is pivotally secured to floor portion  300   b  at the location of axis  105 , and is vertically positioned against the outside of wall portions  200   s - 2  and  200   s - 4 . In turn, floor portion  300   b  is vertically positioned proximate fixed space portion  102 , with wall component  200 P pending from floor portion  300   b  between floor portion  300   b  and wall portions  200   s - 2  and  200   s - 4 . 
     Sizing the enclosure components  155  of structure  150  according to the dimensional relationships disclosed above yields a compact shipping module  100 , as can be seen from the figures. Thus shipping module  100  depicted in  FIG. 3 , when dimensioned according to the relationships disclosed herein using an “E” dimension (see  FIG. 2 ) of approximately 28.625 inches (72.7 cm), and when its components are stacked and positioned as shown in  FIG. 3 , has an overall length of approximately 19 feet (5.79 m), an overall width of approximately 8.5 feet (2.59 meters) and an overall height of approximately 12.7 feet (3.87 meters). These overall dimensions are less than a typical shipping container. 
     It is preferred that the fixed space portion  102  be in a relatively finished state prior to positioning (folding) together all of the other wall, roof and floor portions as described above. In the embodiment shown in  FIGS. 1 and 2 , wall components  200  are fitted during manufacture and prior to shipment with all necessary door and window assemblies, with the enclosure components  155  being pre-wired, and fixed space portion  102  is fitted during manufacture with all mechanical and other functionality that structure  150  will require, such as kitchens, bathrooms, closets and other interior partitions, storage areas, corridors, etc. Carrying out the foregoing steps prior to shipment permits the builder, in effect, to erect a largely finished structure simply by “unfolding” (deploying) the positioned components of shipping module  100 . 
     Each of the wall, floor and roof components  200 ,  300  and  400 , and/or the portions thereof, can be sheathed in protective film  177  during fabrication and prior to forming the shipping module  100 . Alternatively or in addition, the entire shipping module  100  can be sheathed in a protective film. Such protective films can remain in place until after the shipping module  100  is at the construction site, and then removed as required to facilitate enclosure component deployment and finishing. 
     Shipping Module Transport 
     The shipping module  100  is shipped to the building site by appropriate transport means. One such transport means is disclosed in U.S. Pat. No. 11,007,921, issued May 18, 2021; the contents of which are incorporated by reference as if fully set forth herein, particularly as found at paragraphs 0020-0035 and in  FIGS. 1A-2D  thereof. As an alternative transport means, shipping module  100  can be shipped to the building site by means of a conventional truck trailer or a low bed trailer (also referred to as a lowboy trailer), and in the case of over-the-water shipments, by ship. 
     Structure Deployment and Finishing 
     At the building site, shipping module  100  is positioned over its desired location, such as over a prepared foundation; for example, a poured concrete slab, a poured concrete or cinder block foundation, sleeper beams or concrete posts or columns. This can be accomplished by using a crane, either to lift shipping module  100  from its transport and move it to the desired location, or by positioning the transport means over the desired location, lifting shipping module  100 , then moving the transport means from the desired location, and then lowering shipping module  100  to a rest state at the desired location. Particularly suitable equipment and techniques for facilitating the positioning of a shipping module  100  at the desired location are disclosed in U.S. Nonprovisional patent application Ser. No. 16/786,315, entitled “Equipment and Methods for Erecting a Transportable Foldable Building Structure,” and filed on Feb. 10, 2020. The contents of that U.S. Nonprovisional patent application Ser. No. 16/786,315, entitled “Equipment and Methods for Erecting a Transportable Foldable Building Structure,” having the same inventors as this disclosure and filed on Feb. 10, 2020, are incorporated by reference as if fully set forth herein, particularly including the equipment and techniques described for example at paragraphs 126-128 and in connection with  FIGS. 11A and 11B  thereof. 
     Following positioning of shipping module  100  at the building site, the appropriate portions of wall, floor and roof components  200 ,  300  and  400  are “unfolded” (i.e., deployed) to yield structure  150 . Unfolding occurs in the following sequence: (1) floor portion  300   b  is pivotally rotated about horizontal axis  305  (shown in  FIGS. 3 and 4 ) to an unfolded position, (2) wall component  200 P is pivotally rotated about horizontal axis  105  (shown in  FIG. 3  behind perimeter board  312 ) to an unfolded position, (3) wall portions  200   s - 2  and  200   s - 4  are pivotally rotated about vertical axes  192  and  194  (shown in  FIG. 2 ) respectively to unfolded positions, and (4) roof portions  400   b  and  400   c  are pivotally rotated about horizontal axes  405   a  and  405   b  (shown in  FIGS. 3 and 4 ) respectively to unfolded positions. 
     A mobile crane can be used to assist in the deployment of certain of the enclosure components  155 , specifically roof portions  400   b  and  400   c,  floor portion  300   b,  as well as the wall component  200 P pivotally secured to floor portion  300   b.  Alternatively, particularly suitable equipment and techniques for facilitating the deployment of enclosure components  155  are disclosed in U.S. Nonprovisional patent application Ser. No. 16/786,315, entitled “Equipment and Methods for Erecting a Transportable Foldable Building Structure,” and filed on Feb. 10, 2020. The contents of that U.S. Nonprovisional patent application Ser. No. 16/786,315, entitled “Equipment and Methods for Erecting a Transportable Foldable Building Structure,” having the same inventors as this disclosure and filed on Feb. 10, 2020, are incorporated by reference as if fully set forth herein, particularly including the equipment and techniques described for example at paragraphs 132-145 and depicted in  FIGS. 12A-14B  thereof. 
     After unfolding, the enclosure components  155  are secured together to finish the structure  150  that is shown in  FIG. 1 . Perimeter board  312  and roof skirt board  280  provide structures for securing wall, floor and roof components in their deployed positions. If any temporary hinge structures have been utilized, then these temporary hinge structures can be removed if desired and the enclosure components  155  can be secured together. During or after unfolding and securing of the enclosure components  155 , any remaining finishing operations are performed, such as addition of roofing material, and making hook-ups to electrical, fresh water and sewer lines to complete structure  150 , as relevant here. 
     The foregoing detailed description is for illustration only and is not to be deemed as limiting the inventions disclosed herein, which are defined in the appended claims.
