     FIELD OF THE INVENTION 
     This application relates to demountable wall systems, and, more particularly, demountable wall systems and methods for easy installation and customization. 
     BACKGROUND 
     Demountable wall systems, and particularly demountable wall systems using glass panels, are used in both residential and commercial settings. Compared to traditional, fixed wall systems, demountable wall systems include panels (e.g., glass panels, metal panels, wood panels, composite panels, polymer panels, concrete panels, fabric-covered acoustic panels, gypsum, etc.) that can be unmounted, relocated, and reinstalled at new locations relatively quickly, and thus provide increased design flexibility. The panels are also often interchangeable such that the wall system can be customized to the particular needs of the setting (e.g., panels can be swapped for panels with different finishing options, different material properties, etc.). Due to their flexibility, demountable wall systems can be used for a variety of different purposes when installed, including, but not limited to, sound control (acoustical protection), light and solar control, seismic control, safety, air and water resistance, thermal control, clean rooms, emergency egress and ingress, lockability (ability to lock rooms or spaces defined by the wall systems), etc. 
     Traditionally, demountable wall systems include a frame that is positioned within the area or setting to receive the wall system. The frame includes upper frame components, lower frame components, and/or side frame components depending on the particular shape or needs of the wall system. Lower frame components of traditional wall systems often define a channel to receive the glass panel, and a front of the channel has a lip. To install the glass panel, the glass panel is lifted into the channel of the upper frame component such that the panel can clear the lip of the lower frame component, pushed backwards, and then lowered into the channel of the lower frame component. As such, the channel of the upper frame component must have a sufficient depth to accommodate the lifting and lowering action during installation as well as retain the glass panel on the frame after installation. 
     Because the panels are often heavy and the installation requires relatively complex movements in a limited space, installation of the glass panels is not easy, and panels may become damaged if improperly installed. Uninstalling the panel is likewise relatively difficult to perform. Moreover, after installation, a gap may exist between a top of the glass panel and the base of the channel of the upper frame component, which may lead to substandard performance of the wall system due to improper sealing, misaligned or angled panels, etc. Additionally, traditional demountable wall systems are unable to account for any variations in surfaces on which the system is mounted such as warped or slated floors and/or walls, unlevel or non-parallel floors and/or ceilings, etc. 
     Furthermore, in some cases, it can be time-consuming to join two frame components where they meet in a way that has an aesthetically pleasing appearance. Frame components may be joined in various configurations, such as an end-to-end configuration (where frame components are joined through a butt joint or other suitable end to end joint) or a corner configuration (where frame components are joined at an angle from as small as 0.1 degrees to up to 359.9 degrees to form a corner). The term “corner” is understood to mean any joining angle in which the longitudinal axes of both components are not arranged substantially parallel to one another, and the term “straight” or “butt” joint is understood to mean any joining arrangement in which the longitudinal axes of both components are arranged substantially parallel to one another. As such, there is a need for demountable wall systems that are easy to install and customize in various joined configurations. 
     Additionally, in certain cases, it may be preferable to use a sliding door with the demountable wall system to conserve space compared to a conventional swinging door. The use of a sliding door, however, may not provide a suitable sound barrier for the enclosure because the sliding door is typically not snugly fitted against and/or within the door opening. As a result, there is also a need to provide an improved sliding door design that can be used with the demountable wall systems while minimizing the impact on the quality of the sound barrier provided by the demountable wall system.

In other examples, the demountable wall systems include a frame component with a removable back cover. In certain examples, the demountable wall systems include a frame component with a level. In some aspects, the demountable wall systems include a frame component with a front channel and a supplemental channel. In various aspects, the demountable wall systems include a corner joining member. In some examples, the demountable wall systems include a door enclosure mechanism. Various other features are provided below. It will be appreciated that while the features are described separately, a demountable wall system and/or frame component of the demountable wall system may include any combination of features as desired. 
     Demountable Wall System 
       FIGS. 1 and 2  illustrates an example of an improved demountable wall system  100  according to aspects of the preset disclosure. The demountable wall system  100  includes a frame  101  having one or more frame components  104  that support a panel  102  to form a wall or other similar structure. 
     The demountable wall system  100  and may be incorporated into various environments and as such may have various suitable shapes or configurations as desired. In some cases, the demountable wall system  100  may be a stand-alone, self-supporting structure. In other examples, and as illustrated in  FIG. 1 , the demountable wall system  100  may be incorporated as a component of a larger wall  103   
     The frame component  104  of the frame  101  may be an upper frame component, a lower frame components, a side frame component, etc. In some cases where a plurality of frame components  104  are included, the frame components  104  include the same components as discussed below; however, in other examples, one frame component  104  may have features that are different from another frame component  104 . The frame component  104  may be constructed from various materials including, but not limited to, various metals, woods, plastics, composites, fiber-reinforce polymers, other suitable materials, or combinations thereof. In certain examples, the frame component  104  is formed through an extrusion process, although other techniques may be used to form the frame component  104 . In one non-limiting example, the frame component  104  is an extruded aluminum component, but may also be formed of any suitable metal or fiber reinforced polymer, such as carbon fiber. 
     As illustrated in  FIG. 2 , the frame component  104  of the frame  101  defines at least one channel  114 . When the demountable wall system  100  is assembled, at least a portion of the panel  102  is positioned within the channel  114 . The panel  102  may be various suitable types of panels for forming a wall or similar structure including, but not limited to, glass panels, metal panels, wood panels, composite panels, polymer panels, concrete panels, fabric-covered acoustic panels, gypsum, etc. 
     In certain embodiments, the demountable wall system  100  optionally includes an opening or doorway  106  through which a person accesses an area that is at least partially enclosed by the demountable wall system  100 . In order to provide additional privacy and/or some sound proofing, a door  108  may be attached to the panel  102  and/or the frame component  104 . The door  108  may be configured to extend from the floor to the ceiling or may have any suitable height or width that substantially contours to the dimensions of the opening  106 . In other words, the door dimensions may be substantially the same as or slightly smaller than the dimensions of the opening  106  for embodiments where the door  108  fits within the opening  106  in an engaged position, as discussed in more detail below. In other embodiments, the door dimensions may be larger than the dimensions of the opening to ensure that the door overlaps the edges of the opening  106  for embodiments where the door  108  is pressed against the opening  106  in an engaged position, as discussed in more detail below. In further embodiments, the door  108  may be configured to swing or slide into place within the opening  106 . Examples of suitable doors  108  may include solid doors such as barn doors, panel doors, doors with glass or other inserts, framed or frameless glass doors, or other suitable designs. 
     In the example of  FIG. 1 , and as discussed in greater detail below with reference to  FIGS. 23-26B , the door  108  is slidable along a track such that the door  108  can slide between a closed position (in which the door  108  blocks the opening  106 ) and an open position (in which at least a portion of the opening  106  is not covered by the door  108 . In some cases, the track may be attached to an upper portion  116  of the door  108 , a lower portion  118  of the door  108 , or other suitable location. In the closed position, an edge  120  of the door  108  is positioned adjacent to a corresponding edge  122  of the opening  106 . In some cases, the edge  120  abuts the edge  122  in the closed position; however, in other examples, a gasket  124  may be provided on the edge  120  and/or the edge  122  such that the gasket  124  is compressed by the door  108  in the closed position, which may contribute to the sound insulation of the wall system  100 . In other examples, the gasket  124  may be positioned on a surface surrounding the periphery of the opening  106  and/or around the periphery of the door  108  so that the gasket is compressed as the door  108  is pressed against edges of the opening  106 . In other examples, the opening  106  and/or door  108  may be omitted from the demountable wall system  100 . 
     Front Locking Cover 
       FIGS. 3-6  illustrate another example of a frame component  304  that can be used with the demountable wall system  100 . The frame component  304  is substantially similar to the frame component  104  and includes the channel  114  as a first or front channel  114 . In some examples, the frame component the channel  114  includes a gasket  315  or other suitable sealing member for forming a seal with the panel  102  when the panel  102  is positioned within the front channel  114 . Optionally, a back spacer  328  may be positioned between the panel  102  and the frame component  304 . When included, the back spacer  328  may be positioned before or after the panel  102  is positioned on the frame component  304 . 
     Compared to the frame component  104 , the frame component  304  also includes a second or back channel  326 . When included, various infrastructure components such as wiring, piping, securing mechanisms, etc. may optionally be received within the back channel  326 . Optionally, the back channel  326  may be omitted, and the frame component  304  only forms the front channel  114 .  FIG. 15  illustrates an example of a frame component  1504  that is substantially similar to the frame component  304  but omits the back channel  326 . 
     A back cover  330  may at least partially form the back channel  326  and cover the back channel  326 . In some examples, as illustrated in  FIGS. 3-6 , the back cover  330  is monolithically formed with the frame component  304 ; however, in other examples, and as discussed below with reference to  FIGS. 9-12 , the back cover  330  is a separate component that is removably attached to the frame component  304  such that the back channel  326  can be selectively uncovered. The back cover  330  may be constructed from various suitable materials. In some cases, the frame component  304  and back cover  330  are constructed from the same material, although they need not in other examples. 
     As illustrated in  FIGS. 3-6 , compared to the frame component  104 , the frame component  304  optionally includes a removable front cover  332 . When the front cover  332  is assembled with the frame component  304 , the front cover  332  encloses a front portion of the front channel  114  and at least partially overlaps the panel  102 . 
     In examples with the removable front cover  332 , the frame component  304  may define a locking slot  334  generally below the front channel  114 . The locking slot  334  may extend continuously along a length of the frame component  304 , although in other examples, one or more locking slots  334  may be provided at various spaced apart positions along the length of the frame component  304 . As illustrated in  FIGS. 3-6 , in some cases, the locking slot  334  is arcuate-shaped so that it complements the shape of a key  336  of the front cover  332 . 
     As illustrated in  FIGS. 3-6 , the key  336  may be at an intermediate position on the front cover  332  between opposing ends of the front cover  332 . In other examples, the key  336  may be at an end of the front cover  332 . The key  336  may extend continuously along a length of the front cover  332 , although in other examples, one or more keys  336  may be provided at various spaced apart positions along the length of the front cover  332 . In other examples, the locking slot  334  may have other shapes complimentary to the shape of the key  336  such that the key  336 , and thus the front cover  332 , is held in place when the key  336  is positioned within the locking slot  334 . In certain examples, the key  336  and locking slot  334  are shaped such that, when the key  336  is within the locking slot  334 , a purely horizontal force that is parallel to the ground does not dislodge the key  336  from the locking slot  334 . 
     In other examples, the locking slot  334  and key  336  may be omitted, and the front cover  332  may be attached to the frame component  304  using any suitable permanent or non-permanent fastening means. Any suitable permanent or non-permanent fastening means that apply mechanical, electromechanical, piezoelectric, vacuum, magnetic, and/or friction force to join the front cover  332  to the frame component  304  may be used. Examples of mechanical fastening means include, but are not limited to, snap-fit, hook and loop, snaps, clasps, nuts and bolts, screws, pins and rivets, cams, and ratchets. Examples of vacuum fasteners may include, but are not limited to, suction cups and the like. Examples of magnetic fasteners may include, but are not limited to, hidden fasteners that can be turned through application of a magnetic field (such as those described in http://swissinvis.com/products/). Examples of additional fastening means may include, but are not limited to, gravity, crimping, welding, soldering, brazing, taping, gluing, cementing, riveting, magnets, electromagnets, camming, spring closures, snap-fit, hinges, friction lock systems, hook and loop fasteners, dual lock fasteners, zippers, clinching, thermodynamic materials, elastic materials, wedge locking, the use of other adhesives, or various other fastening mechanisms. 
     In various examples, a spacer  338 , such as a wedge gasket or other suitable component, may be positioned between the front cover  332  and the panel  102 . In some examples, as illustrated in  FIGS. 3-5 , the spacer  338  is a separate component that is positionable between the front cover  332  and the panel  102  before or after the panel  102  is positioned within the channel  114 . In other examples, as illustrated in  FIG. 6 , the spacer  338  and front cover  332  are a single component. For example, the spacer  338  can be pre-secured to the front cover  332  or, alternatively, the spacer  338  can be integrally or monolithically formed with the front cover  332 . In addition to forming a seal between the front cover  332  and the panel  102 , the spacer  338  may apply cantilevered pressure on the front cover  332  to further lock the front cover  332  in place on the frame component  304 . 
     A method of installing the panel  102  with the frame component  304  includes positioning the panel  102  in the front channel  114  defined by the frame component  304 . Optionally, positioning the panel  102  in the front channel  114  includes positioning the panel  102  on the gasket  315 . After the panel  102  is positioned, the method may include inserting the key  336  of the front cover  332  into the locking slot  334 . In some aspects, inserting the key  336  includes rotating the front cover  332 . The method may include inserting the spacer  338  between the panel  102  and the front cover  332  such that the spacer  338  applies cantilevered pressure on the front cover  332  to further lock the front cover  332  in place. To disassemble the demountable wall system  100 , the method may include removing the spacer  338  from between the panel  102  and the front cover  332  such that the pressure is no longer applied against the front cover  332 . The method may include removing the key  336  from the locking slot  334 . In some cases, removing the key  336  includes rotating the front cover  332  in an opposite direction from the installation direction. After the front cover  332  is removed, the panel  102  may be removed. 
     With the frame component  304  having the front cover  332 , an installer can easily install and uninstall a panel  102  from demountable wall system  100  without having to lift and lower the panel over a lip as traditionally required. The frame component  304  with the front cover  332  also allows for increased tolerance or variation in the panels  102  compared to traditional systems because the panel  102  does not need to first clear a lip. For example, traditional lift and drop systems can only accommodate minor variations in panel size because the panels  102  must clear the lip to be installed, and any imprecisely measured panels  102  must be discarded because they cannot fit over the lip. In contrast, because the frame component  304  with the front cover  332  does not require the panel  102  to clear a lip, the frame component  304  with the front cover  332  can compensate for any likely imprecision in the measurement of the panel  102  due to the increased space. Thus, the demountable wall system  100  allows for imprecisely measured panels  102 , which would otherwise be discarded in traditional systems, to still be used with the demountable wall system  100 . Additionally, the amount of installation time needed to install the panel  102  on the frame component  304  is reduced because the time needed to carefully clear the lip and/or correct imprecise panels is reduced or eliminated. The increased space provided by the frame component  304  may also allow for larger panels  102  to be used compared to traditional systems. In some examples, the frame component  304  with the front cover  332  may reduce and/or eliminate the need for a lot of secondary fasteners to assemble the wall system, which may further reduce the amount of installation time needed. 
     Leveling System 
       FIGS. 7 and 8  illustrate another example of a frame component  704  that can be used with the demountable wall system  100 . Compared to the frame components  104  and  304 , the frame component  704  includes a leveling system  739  with a leveling base  740  within in the front channel  114 . As illustrated in  FIGS. 6 and 7 , the panel  102  may be assembled with the frame component  704  by positioning the panel  102  on the leveling base  740  within the front channel  114 . The leveling base  740  is vertically adjustable such that a vertical position of the panel  102  can be adjusted and controlled as desired. For example,  FIG. 7  illustrates an example of the leveling base  740 , and thus panel  102 , in a lowest position, and  FIG. 8  illustrates an example of the leveling base  740  in a highest position. 
     The leveling base  740  extends along a length of the frame component  704  such that when the panel  102  is positioned on the frame, the leveling base  740  contacts the edge of the panel  102  along the length of the frame component  704 , and thus along a length of the edge of the panel  102 . In some examples, the length of the leveling base  740  is approximately equal to or greater than the length of at least one of the frame component  704  and the edge of the panel  102 . In such examples, a single leveling base  740  may be provided with the frame component. In other examples, the length of the leveling base  740  is less than the length of at least one of the frame component  704  and the edge of the panel  102 . In such examples, any desired number of leveling bases  740  may be provided with the frame component  704  including, but not limited to, one leveling base  740 , two leveling bases  740 , three leveling bases  740 , more than three leveling bases  740 , or any other desired number of leveling bases  740 . In some examples where the length of the leveling base  740  is less than the length of the edge of the panel  102 , depending on the number of leveling bases  740  utilized, the entire edge of the panel  102  may or may not be in contact with at least one leveling base  740 . 
     In various examples, the leveling base  740  is vertically adjustable through at least one set screw  742 . The set screw  742  may be provided in the front channel  114 , although it need not be in other examples. The disclosure of the set screw  742  should not be considered limiting on the current disclosure, as in other examples, the leveling base  740  may be vertically adjusted through various other suitable mechanisms. Optionally, the set screw  742  is retained on a leveling post  744  of the frame component  704 , although various other suitable mechanisms may be provided to position the set screw  742  relative to the frame component  704 . In certain examples, a plurality of set screws  742  are provided along the front channel  114  such that the leveling base  740  may be adjusted at a plurality of locations. In such examples, the vertical adjustment or position of the leveling base  740  at one location may be the same as or different from the vertical adjustment or position of the leveling base  740  at another location. When a plurality of set screws  742  are included, the set screws  742  may be spaced apart by regular or irregular intervals. 
     Optionally, a height of the set screw  742  may be limited or predefined such that the leveling base  740  cannot be raised too high relative to the frame component  704 . In such examples, the predefined range of vertical adjustment of the set screw and leveling base may prevent the leveling base  740  from being adjusted such that it (and the panel  102 ) are no longer within the front channel  114 . In other examples, the height of the leveling base  740  may be controlled through mechanisms other than set screws while remaining a self-contained level system. For example, leveling mechanisms may include adjustable shims, a setting block, a scissor mechanism, a spindle and glide, a pneumatic system and/or device, a magnetic system, a thread that goes up into frame with a disk on the bottom to adjust for floor, an inflatable device, foam, a magnetic levitation system, pressure expansion devices, offset camming devices, hydraulic devices, shape memory polymers, photopolymers, dialectic elastomers, ionic electroactive polymers, polyelectrolyte gels, gel-metal composites, screws, screw jacks, roller screws, or other suitable devices that can change and control the height of the leveling base  740 . 
     As illustrated in  FIGS. 7 and 8 , the leveling system  739  is a self-contained level system within the frame rather than being an external or additional component. In addition, because the leveling system  739  is self-contained, it may reduce the number of steps needed for installation (because additional tools and/or steps are not needed), the amount of installation time, and provides greater flexibility for how much the panel can be off the floor compared to traditional and external systems. In certain cases, the self-contained leveling system  739  may reduce the installation time by 20-25% compared to traditional wall systems. 
     Optionally, the frame component  704  includes a cover  746 , such as a top gasket or other suitable device, may be provided between the panel  102  and the frame component  704 , and above the leveling base  740 . Similarly, the spacer  338  may be provided between the panel  102  and a forward portion of the channel  114 . 
     A method of installing the panel  102  with the frame component  704  includes positioning the panel  102  in the front channel  114  and on the leveling base  740 . After the panel  102  is positioned, the method includes vertically adjusting at least one set screw  742  such that a corresponding portion of the panel  102  is vertically positioned. In other examples, the method includes first vertically adjusting at least one set screw  742  to vertically adjust the leveling base  740  to a desired vertical position, and after the leveling base  740  is vertically positioned, positioning the panel  102  on the leveling base. 
     The frame component  704  with the leveling base  740  may allow for an installer to quickly and easily ensure that the panel  102  is at a correct position (e.g., level) relative to the surface. In addition, the leveling base  740  allows for increased tolerance or variation in the panels  102  compared to traditional systems because leveling base  740  can be adjusted to compensate for any imprecision in the measurement of the panel  102 , while also ensuring the panel  102  is at a correct position relative to the surface. Thus, the frame component  704  with the leveling base  740  allows for imprecisely measured panels  102 , which would otherwise be discarded in traditional systems, to still be used with the demountable wall system  100 . In addition, the increased space provided by the frame component  704  with the leveling base  740  may allow for larger panels  102  to be used compared to traditional systems. 
     The contact between the leveling base  740  and the panel  102  may also provide improved safety compared to traditional systems. In particular, in traditional systems, the panel  102  only contacts individual shims spaced along the length of the frame, usually two along the entire length of the frame, which presents an opportunity for at least one of the shims and the panel  102  to slip or adjust. In contrast, with the leveling base  740 , and in particular when the leveling base  740  extends along the length of the frame component  704 , the panel  102  is more securely held in place because of contact along the length of the edge of the panel. 
     The contact between the leveling base  740  and the panel  102  may also provide an acoustic benefit such that the wall system  100  has improved acoustical performance compared to traditional systems. Without being bound to any particular theory, it is believed that increasing the amount of contact between the panel and the gasket will result in improved acoustic performance. In traditional systems because the panels  102  are typically only supported by two shims on the frame, a gasket on the shims only contacts the panel  102  at those two points. In contrast, with the demountable wall system  100 , because the leveling base  740  extends along the length of the frame component, a gasket can be provided on the leveling base  740  that extends along the entire edge, or any desired portion, of the panel  102 . In other words, the combination of the gasket and the leveling base  740  has more contact points with the panel  102  thus resulting in improved acoustic performance, such as sound proofing. In some examples, the leveling base  740  that extends along the entire length of the frame component  704  and thus the entire length of the edge may provide the most improved acoustic performance compared to traditional systems. 
     As one non-limiting example illustrating the improved acoustic performance, a panel  102  may be 0.5 inches thick with an edge that is 48 inches. In a traditional system, a traditional shim is about 2 inches long. Assuming that four shims are used in the traditional system (which is typical), the gasket to edge contact with the traditional system and 0.5-inch glass is 4 square inches of contact (i.e., 2 inches long×0.5 inches thick×4 total shims). In this example, it is estimated that such a traditional system would experience a drop or reduction from the original sound transition coefficient (stc) of the panel  102  of about 3-4 stc. By comparison, with the example of the leveling base  740  that extends along the entire length of the frame component  704 , the gasket may have complete contact with the panel along the edge through the leveling base  740 , or about 24 square inches of contact (i.e., 48 inches long×0.5 inches thick×1 leveling base). In this example, it is estimated that the drop or reduction of the stc of the panel  102  would experience a drop of up to 2 stc, such as a drop of 1-2 stc. In other words, the contact between the gasket and the edge of the panel  102  in the demountable wall system  100  was six (6) times the amount of contact between the gasket and the edge of the panel in the traditional system, and such contact minimizes or reduces the drop in stc. In other examples, it is expected that the leveling base  740  would minimize or reduce the drop in stc of a panel  102  constructed of any material as compared to traditional systems. 
     Removable Back Cover 
       FIGS. 9-12  illustrate another example of a frame component  904  that can be used with the demountable wall system  100 . 
     Similar to the frame component  304 , the frame component  904  includes the front cover  332  and the locking slot  334 . However, compared to the frame component  304 , the key  336  of the front cover  332  and the locking slot  334  have a different profile and are substantially planar. 
     Compared to the frame components  104 ,  304 , and  704 , the frame component  904  also includes a removable back cover  930  that selectively covers or provides access to the back channel  326 . In these examples, the back channel  326  can optionally receive the panel  102  within the back channel  326 . Moreover, the back cover  930  can be changed and another back cover  930 , or a supplemental back cover can be installed. 
     In some examples, the back cover  930  is removably attached to the frame component  904  through various suitable connecting mechanisms that allow for secure attachment of the back cover  930  to the frame component  904 . Suitable mechanisms include, but are not limited to, a sliding connection, a snap-fit connection, hook and loop fasteners, various other types of fasteners, combinations thereof, or various other suitable permanent or non-permanent mechanisms. In some cases, the connecting mechanisms may be any suitable permanent or non-permanent fastening means that apply mechanical, electro-mechanical, piezoelectric, vacuum, magnetic, and/or friction force to join the back cover  930  to the frame component  904 . The permanent or non-permanent fastening means for joining the back cover  930  to the frame component  904  may be the same or may be different from the fastening means that can be used to attach the front cover  332  to the frame component  904 . In the present example, and as illustrated in  FIGS. 9-14 , the connecting mechanisms include at least one cover engagement piece  948  on the frame component  904  and a complimentary frame engagement piece  950  on the back cover  930 . 
     In various examples, the back cover  930  with the frame component  904  may be selectively removed and replaced with a different back cover  930  having a different profile, a different shape, etc. The front cover  332  can similarly be removed and replaced with a different front cover  332  having a different profile, a different shape, etc. For example, compared to the back cover  930  and front cover  332  of  FIGS. 9 and 10 , the back cover  930  of  FIG. 11  has a 3D or textured pattern on all visible faces of the back cover  930  and the front cover  332  has a 3D or textured pattern on a side face of the front cover  332 . As a further example, compared to the back cover  930  and the front cover  332  of  FIGS. 9 and 10 , the back cover  930  of  FIG. 12  has a 3D or textured pattern on select visible faces of the back cover  930  (e.g., in  FIG. 11 , the 3D pattern is not on the top visible face) and the front cover  332  has a 3D or textured pattern on a side face of the front cover  332 . As another example, compared to the back cover  930  and the front cover  332  of  FIGS. 9 and 10 , the back cover  930  of  FIG. 13  has a 3D or textured pattern and a different profile (e.g., asymmetrical or any other shape). In some examples, the shape and/or profile of the front cover  332  may match the shape and/or profile of the back cover  930 , although they need not. Various other types of profiles, shapes, etc. may be provided with the back cover  930 , and the back covers  930  illustrated in  FIGS. 9-13  should not be considered limiting on the current disclosure. 
     Supplemental Channel 
       FIG. 14  illustrates another example of a frame component  1404  that can be used with the demountable wall system  100 . As illustrated, compared to the frame components  104 ,  304 ,  704 , and  904 , the frame component  1404  includes a supplemental channel  1452  such that the frame component  1404  can accommodate two panels  102 . In such examples, the frame component  1404  is a universal base that can accommodate both a single panel and a double panel installation. Referring to  FIG. 14 , it will be appreciated that in certain examples, the components illustrated between the supplemental channel  1452  and the front channel  114  (e.g., the channel  326 , a face cover  1454 , etc.) may be omitted. Stated differently, in some examples, the back channel  326  may be omitted, and the demountable wall system  100  includes the frame component  1404  with the supplemental channel  1452  and the front channel  114 . 
     In some examples, the supplemental channel  1452  is substantially similar to the front channel  114  and includes the locking slot  334  for receiving a supplemental cover  1456 . In some cases, the supplemental cover  1456  is substantially similar to the front cover  332 , although it need not be in other examples. Optionally, the supplemental cover  1456  and the front cover  332  of the demountable wall system  100  may include spacers (not shown), such as wedge gaskets or other suitable mechanisms. The spacer (not shown) may be positioned between the supplemental and front covers  332  and  1456 , respectively, and the panels  102  such that they apply cantilevered pressure to the supplemental and front covers  332  and  1456  such that the supplemental and front covers  332  and  1456  are held in place. 
     A method of assembling the demountable wall system  100  with the frame component  1404  includes securing the frame component  1404  to a floor or other surface with a fastener. The method includes positioning a first panel  102  in the front channel  114  and positioning the front cover  332  on the frame component  1404 . The method optionally includes positioning the face cover  1454  on the frame component  1404 . The method may include positioning a second panel  102  in the channel  1452  and positioning the supplemental cover  1456  on the frame component  1404  to cover the channel  1452 . 
     Joining System 
       FIGS. 16-22  illustrate an example of two frame components  1604 A-B that can be used with the demountable wall system  100 . As illustrated, a joining system  1658  joins the two frame components  1604 A-B together and at any angle as desired in the demountable wall system. 
     In some cases, the frame components  1604 A-B each include an internal central receptacle  1660 . The receptacle  1660  is shaped to receive outer edges of a suitable fastener, as discussed in more detail below. In some examples, a back channel (e.g., such as the back channel  326 ) may be the receptacle  1660 , although it need not be in other examples. For the embodiments where the frame components  1604 A-B are joined to form a corner, ends  1662  of two frame components  1604 A-B may be cut at mating angles to each other to form a 90-degree corner or other angled corner as desired. 
     The joining system  1658  includes a fastening mechanism to join the frame components  1604 A-B together. Suitable fastening mechanisms include, but are not limited to any suitable permanent or non-permanent fastening means that apply mechanical, electro-mechanical, piezoelectric, vacuum, magnetic, and/or friction force may be used. Examples of mechanical fastening means include but are not limited to snap-fit, hook and loop, snaps, clasps, nuts and bolts, screws, pins and rivets, cams, and ratchets. Examples of vacuum fasteners may include but are not limited to suction cups and the like. Examples of magnetic fasteners may include but are not limited to hidden fasteners that can be turned through application of a magnetic field (such as those described in http://swissinvis.com/products/). Examples of additional fastening means may include but are not limited to gravity, crimping, welding, soldering, brazing, taping, gluing, cementing, riveting, magnets, electromagnets, camming, spring closures, snap-fit, hinges, friction lock systems, hook and loop fasteners, dual lock fasteners, zippers, clinching, thermodynamic materials, elastic materials, wedge locking, the use of other adhesives, or various other fastening mechanisms. In some examples, and to facilitate fastening of these two frame components  1604 A-B, the fastening mechanism may be incorporated into one or both frame components  1604 A-B. 
     In the example of  FIGS. 16-22 , the fastening mechanism of the joining system  1658  includes a first fastener  1664  and a second fastener  1666 . In some cases, the first fastener  1664  and second fasteners  1666  are drawing or cam fasteners. As best illustrated in  FIGS. 20 and 21 , the first fastener  1664  may include an interfacing surface  1668  that is engageable with an adjustment tool  1670 . In some embodiments, the first fastener  1664  is positioned within an interior location, such as an open channel  1672 , of the frame components  1604 A. In some cases, the open channel  1672  may optionally be at least one of the front channel  114  and the supplemental channel  1452 , although it need not be in other examples. the first fastener  1664  may be attached to the interior location of the frame component  1604 A to limit unintended movement of the first fastener  1664  along the open channel  1672 . 
     Optionally, an access portal  1674  may be formed in one or both of the frame components  1604 A-B that provides access to the first fastener  1664  within the open channel  1672 . The access portal  1674  may be formed in an interior side  1676 , an exterior side, top, or other location. The adjustment tool  1670  may be inserted through an access portal  1674  to engage with the interfacing surface  1668 . However, in other embodiments, the adjustment tool  1670  may not need to physically engage with the interfacing surface  1668 . The adjustment tool  1670  may include a wrench, screwdriver, drill, ratchet mechanism, or other suitable tool. 
     In some embodiments, an end  1678  of the second fastener  1666  may be engaged with the receptacle  1660  in the frame component  1604 B. In some embodiments, the end  1678  includes one or more extensions that selectively engage with the receptacle  1660  to prevent the second fastener  1666  from rotating when the first fastener  1664  is adjusted, thereby allowing the first fastener  1664  to induce a movement of the second fastener  1666  relative to the location of the first fastener  1664 . In other words, the first fastener  1664  may be rotated by the adjustment tool  1670 , and this rotation causes the second fastener  1666  to move towards or away from the first fastener  1664 , depending on the direction of rotation of the first fastener  1664 . 
     In further embodiments, a third fastener  1682 , including but not limited to the fasteners described in WO2014/005173, as well as any type of drawing or cam fastener may be coupled to an opposing end  1680  of the second fastener  1666 , and this third fastener  1682  engages with the corresponding receptacle  1660  in the frame component  1604 B. In some embodiments, the third fastener  1682  includes one or more extensions or wings  1683  that selectively engage with the receptacle  1660 . 
     In certain embodiments, once the second fastener  1666  (or third fastener  1682 ) is engaged with the receptacle  1660  of the frame component  1604 A, the first fastener  1664  may be adjusted in a manner that causes the second fastener  1666  to be pulled in the direction of the first fastener  1664 . By doing so, the ends of the frame components  1604 A-B are brought into close proximity with each other and into a snug joint. 
       FIG. 28  illustrates another example of a joining system  2858  for frame components. Compared to the joining system  1658 , the joining system  2858  includes a bracket  2801  having a first arm  2803  and a second arm  2805 . In this example, the bracket  2801  is positioned within the second or back channel  326  defined by a frame component  2704  and covered by a cover  2730 . 
     Door Support System 
     As described above with reference to  FIG. 1 , in some examples, the demountable wall system  100  includes the door  108  that is capable of moving (e.g., sliding) into place in front of the opening  106 .  FIGS. 23-26B  illustrate an example of a door support system  2388  for the door  108  of the demountable wall system  100 . 
     As illustrated in  FIG. 23 , the door support system  2388  includes a track  2390  and a bracket system  2392 . In some examples, the track  2390  is attached to the upper portion  116  or the lower portion  118  of the door  108 . The track  2390  may be positioned on at least one of the floor and the ceiling of the opening  106  and has a length that allows the door  108  to slide between the closed position (see, e.g.,  FIG. 26B ) and the open or retracted position (see, e.g.,  FIG. 1  and  FIG. 26A ). 
     In some examples, the bracket system  2392  includes one or more brackets  2394  that are attached the upper portion  116  of the door  108  when the door  108  is suspended from the track  2390  mounted in the ceiling of the opening  106 . In other examples, one or more brackets  2394  attached to the lower portion  118  of the door  108 , to both the upper portion  116  and the lower portion  118 , or various other suitable locations. In further embodiments, one or more of the brackets  3294  may extend substantially along an entire width of the door  108 . The one or more brackets  2394  are attached to the track  2390  using any suitable fastening means that allows the door  108  to slide between retracted and closed/engaged positions. Such fastening means may include but are not limited to rollers, ball bearings, springs, cables, magnetic connections, electro-mechanical connections, camming retraction mechanisms, modified slide track, pneumatic connections, and hydraulic connections, or various other suitable fastening means. Each bracket  2394  may include a track roller  2396  positioned on an end opposite a location where the bracket  2394  is attached to the door  108 . The bracket  2394  includes a neck  2398  that extends away from the door  108  and connects to at least the track roller  2396 . Each track roller  2396  may be positioned on the bracket  2394  so that a circumferential surface  2381  of the track roller  2396  is positioned facing the door  108  and a planar surface  2383  of the track roller  2396  is positioned substantially parallel to the door&#39;s majority surface plane  2385 . 
     As illustrated in  FIG. 24 , the track  2390  may include a receptacle  2387  that is shaped to receive the track rollers  2396 . The receptacle  2387  may be partially enclosed by a pair of lips  2389  that are shaped to receive the neck  2398  of the bracket  2394 . These track rollers  2396  may have a sufficient thickness that allows the track rollers  2396  to be retained within the track  2390  by the lips  2389 . The track rollers  2396  are configured to travel along the surface of the receptacle  2387  that is positioned below the track rollers  2396  as the door  108  slides between the closed position and the retracted position. In some embodiments, this surface may be the pair of lips  2389  when the lips  2389  form the lower surface of the receptacle  2387 . In other embodiments, the pair of lips  2389  may form a side or an upper surface of the receptacle  2387 . 
     To provide additional privacy and sound control, the door  108  may be configured to transition from a nearly closed position in front of the opening  106 , as shown in  FIG. 26A , to an engaged position where the door  108  is positioned within the opening  106  or pressed tightly against the opening, as shown in  FIG. 26B . To facilitate movement into the engaged position, each bracket  2394  may include at least one engaging roller  2391  that is positioned between the track roller  2396  and the door  108 . The engaging roller  2391  may be oriented substantially perpendicular to the track roller  2396  such that a planar surface  2383  of the track roller  2396  is positioned substantially perpendicular to the door&#39;s majority surface plane  2385 . The bracket  2394  can then be attached to the track  2390  by any suitable design or configuration, such that the engaging roller  2391  may be used that does not interfere with the operation of the conventional door sliding mechanism. 
     In these embodiments, the track  2390  may include an additional area  2393  that is shaped to receive the engaging rollers  2391 . These engaging rollers  2391  pass through the additional area  2393  as the door  108  moves along the track  2390 . At the location where the door  108  reaches the closed position, as illustrated in  FIG. 26A , one or more offset turn mechanisms  2395  may be positioned adjacent some or all of the engaging rollers  2391 . The offset turn mechanisms  2395  may include a cutout region  2397  that is shaped to conform to a portion of the circumferential surface of the engaging rollers  2391 . When the door  108  reaches the closed position, as illustrated in  FIGS. 24, 25A, and 26A , the engaging rollers  2391  contact a leading edge  2399  of the cutout region  2397 , which causes the offset turn mechanisms  2395  to rotate about their axes. As the offset turn mechanisms  2395  rotate, as illustrated in  FIGS. 25B and 26B , the engaging rollers  2391  are pulled about an arcuate path of the cutout region  2397  until the engaging rollers  2391  reach a position approximately 180 degrees from the position where the engaging rollers  2391  first contacted the offset turn mechanisms  2395  in the closed position. The offset turn mechanisms  2395  are configured to cease rotation once the engaged position is reached, as shown by the position illustrated in  FIGS. 25B and 26B , and the door  108  has been pulled into the opening  106  by the rotational movement of the offset turn mechanisms  2395 . 
     In other embodiments, instead of an arcuate motion, a perpendicular track may be located at the position where the door  108  reaches the closed position, and the door  108  may transition by allowing the engaging rollers  2391  to move along this perpendicular track to position the door  108  in the engaged position. In yet other embodiments, the track rollers  2396  may have a spherical shape, similar to that of a ball bearing that is able to transition between the track  2390  and the offset turn mechanisms  2395  or perpendicular track without the need for an additional engaging roller  2391 . 
     In further embodiments, a handle (not shown) may be used in place of the offset turn mechanisms  2395  and engaging roller  2391 . However, any suitable releasable mechanism that allows the door to be pressed against or within the opening  106  may be used. By inclusion of the translational movement mechanism, the sliding door mechanism attains improved acoustic properties over conventional sliding doors that do not include an additional engaged position. In addition, by using a 90-degree turning mechanism at the end of the track  2390 , the depth of travel needed by the door  108  is minimized. 
       FIGS. 27 and 28  illustrate another example of a frame component  2704  that can be used with the demountable wall system  100 . In various examples, the frame component  2704  may be used as both a top frame component and a bottom frame component of the demountable wall system. 
     Similar to the frame component  304 , the frame component  2704  includes the front channel  114  and the back channel  326 . Compared to the frame component  304 , the frame component  2704  includes additional channels. For example, as illustrated in  FIGS. 27 and 28 , in addition to the front channel  114  and back channel  326 , the frame component  304  defines a track channel  2705  that at least partially accommodates an alignment track  2707  of the frame component  2704 . In various cases, the alignment track  2707  may be pre-installed on a surface through various suitable mechanical or chemical fasteners (screws  2709  are illustrated in  FIG. 27 ), and the frame component  2704  may be installed on the track  2702 . In these examples, the alignment track  2707  may allow for the type or configuration of the frame component to be changed as desired. Optionally, various suitable connectors  2717  may selectively connect the frame component  2704  with the alignment track  2707 . 
     The frame component  2704  also includes a cover  2730  that is substantially similar to the back cover  930  except that the cover  2730  further includes a locking projection  2711  extending from a cover body  2723 . When the cover  2730  is assembled with the frame component  2704 , a biasing gasket  2713  (or other suitable device) engages the locking projection  2711  and biases the locking projection  2711  away from the biasing gasket  2713 . The biasing gasket  2713  may be on a biasing element support  2721 . In various examples, the engagement between the biasing gasket  2713  and the locking projection  2711  maintains or promotes engagement between the engagement pieces  948 ,  950  (or other connecting mechanisms connecting the cover  2730  and the frame component  2704 ). As illustrated in  FIGS. 27 and 28 , the cover body  2723  includes a top portion  2725  and a side portion  2727 . 
     As illustrated in  FIGS. 27 and 28 , similar to the frame component  704 , the frame component  2704  also includes the leveling system  739  with the leveling base  740 . As best illustrated in  FIG. 27 , in this example, the sealing gasket  315  is provided on the leveling base  740  such that a seal can be formed between the leveling base  740  and the panel positioned on the leveling base  740 . 
     Similar to the frame component  304 , the frame component  2704  also defines the locking slot  334  that selectively receives the key  336  of the front cover  332 . Compared to the frame component  304 , the profile of the locking slot  334  of the frame component  2704  progressively decreases in height. In some examples, the decreasing height of the locking slot  334  may facilitate the guidance, positioning, and retention of the key  336  within the locking slot  334 . In various examples, and compared to the frame component  304 , the frame component  2704  also includes a key lock  2715 . In certain aspects, and as best illustrated in  FIG. 27 , the key lock  2715  selectively engages the key  336  when the key  336  is positioned within the locking slot  334 . In certain aspects, the key lock  2715  restricts or prevents purely horizontal movement of the key  336  within the locking slot  334 . In various aspects, the key lock  2715  also engages the front cover  332  such that the front cover  332  is pivotable on the key lock  2175 . 
     In some examples, the frame component  2704  includes a covering member  2719  such as foam, various plastics, rubbers, composites, etc. under the frame component  2704  and/or under the alignment track  2707 . In some cases, the covering member  2719  may further compensate for any variations in the surface on which the frame component  2704  is installed. 
     It will be appreciated that although various features are described separately with respect to the demountable wall systems  100 , various other demountable wall systems may include various combinations or sub-combinations of the various features disclosed. For example, the features of the frame components  104 ,  304 ,  704 ,  904 ,  1404 ,  1504 ,  1604 , and  2704  may be used in various combinations to form new frame components, and/or any of the aforementioned frame components may be used in various combinations in a single wall system. Various other demountable wall systems may include various other combinations or sub-combinations of features as desired.
