This application claims benefit under 35 U.S.C. 119(e) of Provisional Application Ser. No. 62/077,515, filed Nov. 10, 2014, the entirety of which is incorporated herein by reference.


FIELD OF THE INVENTION
The present invention relates generally to insulating wall assemblies in which framing members are attached to rigid insulation panels in order to support wall finishing panels at a spaced distance from interior faces of the rigid insulation panels, and more particularly to an insulating wall assembly of this type in which a plurality of supports are partially embedded into the insulation panels so to reach outward from the interior faces thereof for fastening of the framing members to these supports in an adjustable enabling plumb installation of the framing members.
BACKGROUND
Applicant's prior U.S. Pat. No. 8,640,416 discloses a concrete insulation system (CIS) for improving insulation of concrete walls e.g. foundation walls, by mounting rigid foam insulation panels over the interior surface of the concrete, while providing adjustable mounting of wall framing members that enables plumb positioning of same in order to attain a truly planar and vertical interior wall when drywall sheets or other wall finishing panels are mounted over the framing members.
In the aforementioned patent, framing members of T-shaped cross-section each had the web or stem of its T-shaped cross section adjustability received in a groove or slot of a respective foam post that was adhered to the concrete wall in a position matingly fitted between two adjacent insulation panels.
Applicant has developed a new CIS with a unique combination of elements that eliminates the need for foam posts between the adjacent insulation panels, and may be used to reduced the number of bulky components required to assemble the CIS, thereby improving the ease of installation and ease and cost of transport to the installation site.

DETAILED DESCRIPTION
FIG. 1 illustrates a horizontal cross-section of an insulating wall assembly 10 according to an embodiment of the invention, as taken from a plane perpendicular to the major surfaces of a vertically-erect concrete foundation wall 100 of a building.
The insulating wall assembly 10, hereinafter also referred to as a “wall assembly” for brevity, includes a plurality of rigid foam insulation panels 12 each having a non-coated exterior face 14 that faces toward the concrete foundation wall 100 and away from an interior space of the building, an interior face 16 that faces away from the concrete foundation wall 100 into the interior space of the building and that is optimally coated with a reflective layer for enhancing the resistance to heat transfer such as through radiation. Perimeter edges of the panel include opposing top and bottom perimeter edges, and two opposing vertically upright side edges 18, 20. One of the upright side edges 18 features a male tongue 22 spanning the vertical length thereof and projecting laterally outward from the remainder of the side edge 18. The other upright side edge features a female groove 24 recessed therein and spanning the vertical length thereof. The tongue and groove are of mating size and shape, whereby insertion of the tongue of one of the panels 12 into an adjacent one of the panels cooperatively fits the tongue and groove together so as to join the adjacent panels together end-to-end in coplanar relationship with one another.
The joined together panels 12 are attached to the concrete foundation wall 100 by adhesive, or other suitable attachment means, in a position placing the exterior faces 14 of ten insulation panels 12 in abutment against the concrete foundation wall 100. The insulation panels each have the same uniform thickness between their interior and exterior faces 14, 16, and the mating tongue and groove at the interface 26 between each pair of adjacent panels maintains this uniform thickness so that the mating panels form a uniform layer of insulation over the interior surface 16 of the concrete foundation wall 100. This insulation layer is formed exclusively by the series of insulation panels 12, with no intermediates between them.
Each insulation panel 12, at one or more intermediate locations between the two upright side edges 18, 20 thereof, features a narrow elongated slot 28 of rectangular cross-section that runs linearly between a horizontal top edge of the panel and an opposing horizontal bottom edge thereof. The slot folllows a vertical path between these top and bottom perimeter edges, each of which spans between the two vertically upright side edges 18, 20 of the insulation panel so that these four perimeter edges cooperatively define the overall rectangular perimeter of the panel. The slot is recessed into the panel 12 from the interior face 16 thereof, with a depth that reaches partially through the panel toward the opposing exterior face 14, but stopping short thereof. In other words, the depth of the slot 28 is less than the thickness of the panel 12.
FIGS. 1 and 2 illustrate the wall assembly 10 in a fully installed state, in which a plurality of framing member support clips 32 have been anchored in each slot 2. In each slot 28, the respective set of support clips are vertically spaced from one another along the slot's linear path between the top and bottom perimeter edges of the panel. For each slot 28, a respective upright framing member 34 is provided in the form of a length of right-angle channel, and has one of its two cross-sectional legs 34a engaged with the respective set of clips 32 that are anchored in the slot 28. Accordingly, the longitudinal dimension of the framing member 34 stands vertically upright in front of the interior face 16 of the insulation panel 12. The second cross-sectional leg 34b of the framing member 34 lies perpendicularly cross-wise to the first leg 34a in cross-sectional planes of the framing member (i.e. planes lying normal to the longitudinal dimension of the framing member 34). This second cross-sectional leg 34b is situated at a distance spaced outwardly from the interior face 16 of the panel 12 past the distal ends of the clips 32 that project outward from the interior face 16 of the panel 12
With a series of framing members 34 installed in this manner so to reside at horizontally spaced intervals along the plane of the insulation panels 12, and with each framing member being carried by the clips 32 of a respective one of the slots 28, sheets or panels 36 of drywall or other wall finishing material can be fastened to the second legs 34b of the framing members in edge-to-edge relation with one another so as to form a generally continuous and planar finished interior wall surface of the wall assembly. The outer surface of the second cross-sectional leg 34b facing away from the interior face of the insulation panel presents a surface for placement and fastening of the drywall or other finishing panels. The framing members act to the space the wall finishing panels outward from the interior faces 16 of the insulation panels 12. This space between the insulation panels 12 and the wall finishing panels 36 may be left empty to define an airspace between them, or may be partially or entirely filled with additional layers of insulation material (e.g. fiberglass batt insulation). In either case, the air-filled or insulation-filled gap contributes to the thermal insulation performance of the wall assembly.
FIGS. 3 and 4 show one of the clips 32 in isolation, and disclose further detail of the clip structure than revealed by the schematically illustrated and partially embedded clips 32 of FIGS. 1 and 2. Each clip features a barbed fin 38 that forms an insertion portion of the clip 32 that is engaged into the respective slot 28 of the insulation panels 12 during assembly of the wall system. A thickness TU of the unbarbed areas 38a of the fin 38 is approximately equal to the width of the slots 28 in the insulation panels 12, which are preferably predefined slots created during manufacture of the panels 12. The barbs 38b that project laterally outward from the fin at spaced intervals therealong are dimensioned to allow the fin 38 to be manually forced into the slot, against the frictional resistance that is created between the tips of the barbs and the foam walls of the slot 28. After insertion of the clip 32 in the slot, there is enough interference between the tip-to-tip barb width TB of the clip and the predefined width of the panel slot 28 to frictionally hold the clip 32 in place at its inserted position in the slot, at least one a temporary basis. Accordingly, at the building site at which the insulating wall 10 is to be installed, an installer can manually insert a respective set of two or more clips into several slots (e.g. all the slots along a particular foundation wall that is to be insulated), before moving on to a next step of further anchoring the clips in place later, as described herein further below.
With continued reference to FIGS. 3 and 4, a stop flange 40 of the clip 32 lies perpendicularly to the barbed fin 38 at one end thereof, and projects laterally outward from both sides of the fin 38. A width WF of the stop flange 40 exceeds the width of the slot 28 in the insulation panel 12, whereby the stop flange 40 limits the distance by which the barbed fin 38 can be inserted into the slot. That is, once the fin 38 is fully inserted into the slot 28, the stop flange 40 abuts against the interior face 16 of the insulation panel 12 on either side of the slot 28 in order to prevent further penetration of the clip 32 into the insulation panel. The stop flange 40 thus defines a positioning portion of the clip that governs the fully inserted position of same.
On the side of the stop flange 40 lying opposite to the barbed insertion fin 38, the clip 32 features two clip walls 42 each lying parallel to the plane of the fin 38 on opposite sides thereof, and extending from the flange 40 in the direction opposite the fin. The space between the two clip walls 42 equals or slightly exceeds the thickness of the leg 34a of the framing member that is to be fastened to the clip 32, whereby this fastening leg 34a of the framing member can be slid into the space between the two clip walls 42 at the distal end of the clip. The space between the two clip walls 42 thus acts as a slot into which the fastening leg 34a of the framing member 34 is insertable, whereby the clip walls 42 define a slotted fastening portion of the clip 32. When the clip 32 is inserted in to one of the slots 28 in the insulation panels 12, the barbed fin 38 lies in the same vertical plane as the slot 28, and the clip walls 42 lie in respective vertical planes that are perpendicular to the interior face 16 of the insulation panels, parallel to the plane the slot 28, and located on opposing sides of the slot 28.
Each clip wall 42 features one or more lines of weakness 44 (specifically two such lines in the illustrated embodiment, although the number may vary) where the wall thickness is reduced relative to the remainder of the wall 42 in order to create a break-line or cut-line along which the wall 42 can be snapped or cut to reduce the length of the wall LW, as measured from the stop flange 40. In the illustrated embodiment, each such line of weakness is formed by a v-shaped groove running perpendicularly from a top edge 42a of the wall 42 to an opposing bottom edge thereof 42b on an inner side of the respective clip wall 42 that faces the other clip wall 42. Alternatively, each line of weakness may be formed by a recess or groove on the outer side of the clip wall 42, or by a respective pair of recesses or grooves on both sides of the clip wall. A distal section of the clip wall 42 situated on the side of break or cut line 44 opposite the stop flange 40 can be snapped off (e.g. manually, or with the aid of tools, such as pliers) or cut off with a pair of scissors or tin snips, a utility knife, or the other cutting tool.
With reference to FIG. 1, this ability to reduce the wall length LW of the clip 32 can be used together with selection of angle shaped framing members 34 of shorter cross-sectional leg length to reduce the size of the air space or gap G between the interior faces 16 of the insulation panels 12 and the wall finishing panels 36. That is, trimming the wall length LW of the clips 32 shortens the distance by which the clips 32 extend from the interior face 16 of the insulation panels 12, and thus allows shortening of the distance by which the drywall support legs 34b of the framing members 34 are spaced from the insulation panels 12 in the finished wall assembly 10.
In the illustrated embodiment, the insertion fin 38 of the clip 32 is of flat plate-like or planar form, except at the barbs 38a thereof. As a result, a longitudinal dimension of the insertion fin 38 measured in the lengthwise direction of the slot 32 exceeds the thickness of the fin by several times, and a lengthwise span of the slot 32 occupied by the fin is therefore notably greater than that the slot width. Abutment of the opposing sides of this plate-like fin 38 with the opposing sides of the slot resists twisting of the clip about an axis normal to the interior surface of the insulation panels better than other clip embodiments featuring a post or shaft-like insertion portion whose dimensions across and along the slot are equal or similar to one another. The illustrated embodiment uses multiple clips per slot at vertically spaced positions therein, each clip being many times shorter than the slot in this longitudinal dimension. Another embodiment may instead employ a single clip of notably greater length in each slot to support the respective framing member over a substantial length thereof. However, using a set of two or more smaller clips provides sufficient support strength for the framing members, reduces the clip size for more convenient handling and more efficient transport, and reduces the overall material cost of the wall assembly.
After the clips 32 have been inserted into the slots 28, preferably during on-site installation of the wall assembly 10, the clips 32 are then anchored more securely and permanently to the insulation panels by application of spray foam insulation 46 into the slots, at least at the portions of the slots where the barbed insertion fins 38 of the clips 32 reside. The spray foam fills in any empty space between the insertion fin 38 and the foam walls of the slots 28. Allowed to set or cure, the spray foam bonds to the foam walls of the slots. As a result, the barbed insulation fin 38 of the clip 32 is now embedded within the resulting foam body made up of a combination of the insulation panel's original factory-provided foam content, and the hardened spray foam that was applied at the installation site. The clip 32 is therefore now firmly and permanently anchored to the insulation panel.
The clips 32 may be installed in the forgoing manner either before or after erection and attachment of the insulation panels 12 at the concrete foundation wall. After such erection and attachment of the insulation panels, and either before or after attachment of the clips 32 thereto, an upper frame connector 48 is installed in a position running horizontally parallel to the plane of the insulation panels 12 at short distance outward from the interior face 16 thereof at or near the plane of the of the top edges of the insulation panels 12. The upper frame connector 48 is secured in this position by fastening of the upper frame connector to a suitable overhead support structure, such as the bottom edges of a series of overhead floor or ceiling joists 50 that are situated above the insulation panels, as shown in FIG. 2. The upper frame connector 48 of the illustrated embodiment is made of the same right angle channel as the framing members 34, and has one cross-sectional leg 48a thereof fastened to the underside of the floor or ceiling joists 50. The other cross-sectional leg 48b of the upper frame connector 48 lies perpendicularly to the first leg 48a, and hangs downwardly therefrom.
With the upper framing connector 48 and the clips 32 both secured in place, each framing members 34 is then installed. To do this, the fastening leg 34a of the framing member is slid into the slotted space between the two clip walls 42 of each clip 32 in the respective slot 28 of the insulation panels, and in doing so the upper end of the frame member 34 is lifted up into the space between the insulation panels 12 and the hanging leg 48b of the upper framing connector 48. Here, the upper end of the drywall support leg 34b of the framing member is fastened to the hanging leg 48 of the upper framing connector 48 so as to hang the framing member 34 from the hanging leg 48b on the side thereof facing the insulation panels 12. This can be seen in FIG. 7 where screw 52 hangs the framing member 34 from the upper framing connector 48.
In this state, where the framing member is supported solely by this single-point fastening at the upper frame connector 48, the framing member 34 acts as a pendulum to self-plumb itself (i.e. self-align itself into a vertical orientation) in the plane of the slot 28, as the currently free-hanging bottom end of the framing member 34 will swing itself into vertical alignment below the fastened top end of the framing member. Under such pendulum-like action of the framing member 34, the fastening leg 34a of the framing member will swing toward or away from the stop flanges 40 of the respective set of clips within the slotted space between the clip walls 42 thereof.
At this point, with the framing member hanging in a truly vertical orientation in the plane of the slot 28, regardless of whether the trueness of the insulation panel 12 in this plane, which may vary e.g. due to an uneven interior surface of the concrete foundation wall 100, the framing member 34 is then fastened to the respective set of clips 32. This can be seen in FIGS. 5 and 6 where a screw 54 has been driven through the two clip walls 42 of the clip 32, and in doing so, engages through the supporting fastening 34a of the framing member to fasten it in place within the slotted space of the clip 32.
To further reinforce the installed positions of the framing members 34, a lower framing connector 56 is then added in order to join together the lower ends of the framing members 34 in a manner similar to that in which the upper framing connector 48 joins together the upper ends of the framing members. The illustrated lower framing connector 56 may be the same type of right angle channel as the upper framing connector 48. One of the lower connector's cross-sectional legs 56a is fastened to the floor so that it's other cross-sectional leg 56b stands upward therefrom, and the first cross-sectional leg 56a is slid into place the under the lower ends of the framing members 34 until the second cross-sectional leg 56b of the lower framing connector 56 abuts up against the drywall support legs 34b of the framing members 34. With the framing members self-plumbed into a proper vertical orientation, this will automatically align the lower framing connector 56 with the upper framing connector 48. The upstanding cross-sectional leg 56b is then fastened to the drywall support leg 34b of each framing member 34, as shown by screw fastener 58 in FIG. 8.
With the framing members and connectors all assembled in this manner to form a similar framework similar to a traditional stud wall (in which the framing members 34 correspond to the studs, and the upper and lower framing connectors 48, 56 correspond to the top and bottom plates), the framework is now ready for the mounting of drywall or other finishing panels 36 thereto. The drywall support legs 34b of the self-plumbing framing members 34 lie coplanar with one another in a vertical plane in order to support these finishing panels 36 in a proper coplanar, vertical condition for a flat and true finished wall. As shown in FIG. 1, the vertical edges of adjacent finishing panels 36 are abutted against one another in front of the drywall supporting leg 34 of one of the framing units for fastening of both panels to this same framing member. Additional fasteners may be used to secure the finishing panels 36 to the hanging leg 48b of the upper framing connector 48 near the top edges of the finished wall, and to the upstanding leg 56b of the lower framing connector 56 near the bottom edges of the finished wall.
The slots 28 in the insulation panels are preferably created during the manufacturing process, whereby an accurate linear path of the factory-defined slots ensures alignment of the clips 32 of each set with one another during on-site assembly, and installation time is reduced compared to other embodiments in which creation of clip-accommodating slots is instead performed on-site during the installation process. As an alternative to vertical slots 28 running between top and bottom edges of the insulation panels, horizontal slots could be employed to accommodate mounting of the clips, where one slot would accommodate a single clip in each set of vertically spaced clips to which a respective framing member is to be mounted. In another embodiment, instead of mounting multiple clips within an elongated slot spanning all or a substantially majority of the insulation panel, an array of recesses or openings at predefined positions spaced out over the interior faces of the insulation panels may be used to individually mount each support clip. As an alternative to using recesses or openings to accommodate mounting of the clips, other embodiments may embed the clips into the insulation panels as part of the manufacturing process. However, on-site post-manufacture installation of the clips is preferable due to the ability to flat-pack the insulation panels together at their interior and exterior for space and cost efficient transport and handling.
Although the framing member supports 32 are described above as clips due the dual-wall configuration 42 of the slotted fastening portion of the clip that embraces around both sides of the fastening leg 34a of the framing member, other embodiments may have a single wall effectively acting as a fastening flange that resides on only one side the fastening leg 34a of the framing member. In other words the fastening leg 34a of each framing member may be placed face-to-face beside a flat, unslotted fastening portion of a single wall support, or placed face-to-face with both walls of a slotted fastening portion like that of FIGS. 3 and 4.
In one embodiment, the air gap G in the finished wall assembly may preferably be approximately 2′′ wide to accommodate the installation of electrical boxes. In areas where electrical boxes are typically not located however, an air gap of approximately 3⁄4′′ wide may be sufficient to provide a suitable insulating capacity. The foam core material of the insulating panels 12 may be Expanded Poly-Styrene (“EPS”) foam sheets with a desirably sufficient insulation and R-value. In some embodiments, the exterior face of the foam panels in contact with the foundation wall may each optionally include a reflective layer such as a foil layer, similar to the reflective layer coated on the interior face of the foam panels, to act as a vapour barrier to resist the diffusion of moisture through the foundation wall, and to reduce radiative heat transfer from outside the structure during summer, for example.
The clips are preferably plastic, but may alternatively be formed of metal or other materials that would provide suitable support strength and allow fastening together of the clips and framing members. The framing members are preferably made of lightweight metal channel, but other materials may alternatively be employed. While the illustrated framing members are right-angle channel, other cross-sectional shapes also having divergent cross-sectional legs oriented at right-angles to one another may be employed. For example, T-shaped framing members of the shape disclosed in the Applicant's aforementioned patent may alternatively be used. However, right-angle channel reduces the material cost and weight of the framing member, and has the advantage that right-angle channel is readily and affordably available in the marketplace. As another alternative, closed rectangular channel members could be used, in which case adjacent sides of the channel form perpendicularly diverging legs of its cross-sectional shape for respective mating with the supports and drywall, but again, right-angle channel may be preferred in the interest of material efficiency.
FIGS. 9 and 10 illustrate an unslotted support 32′ featuring a single-wall fastening portion 42′. As shown in FIG. 9, this support 32′ features a through-hole 64 in the fastening portion 42′ near the stop flange 40. Turning to FIG. 10, the through-hole 64 enables routing of electrical wiring 66 or other lines (e.g. speaker wire; or copper pipe, PEX tubing or other small plumbing conduits) through the air gap G behind the framing members 34, i.e. between the framing members 34 and the insulation panels 12. As shown, this enables an electrical line to run from one side of a framing member to another via the through-hole 64, for example to reach an electrical box (e.g. light switch, outlet or junction box) 68 mounted in the wall cavity between two adjacent framing members 34. The drawing illustrates one such example, in which the electrical box is fastened to the fastening leg of a respective framing member on the free side thereof facing away from the single-walled fastening portion 42′ of the respective support 32′. It will be appreciated that the slotted support 32 of FIG. 4 may likewise be provided with a through-hole 64 opening through both walls of its fastening portion 42 for routing of electrical wiring or other lines through the support behind the respective framing member. The use of a pre-defined through hole in each support enables easy routing of utilities or the like without having do drill, cut, punch or otherwise create holes in the framing members, which also serves to better retain the structural integrity of the framing members.
Although disclosed in the context of a concrete insulating wall assembly, the invention may be employed in various applications to provide insulation capacity in various types of buildings, including concrete, steel, post frame, animal confinement, and quonset and tarp buildings, for example. Although the illustrated embodiment employs vertically oriented slots and framing members lying cross-wise to the top and bottom edges of the insulation panels, other embodiments may employ other orientations, while still providing a suitable framework for attachment of drywall or other finishing materials, such as horizontal slots and framing members spanning between the opposing upright side edges of the panels, or obliquely angled slots and framing members. However, vertically upright orientation of the framing members is preferred, at least partly due to the self-plumbing functionality achievable by hanging of such upright framing members from an upper framing connector.
The spacing between the slots 28, and the resulting spacing between the installed sets of clips and installed framing members may be varied. For example, insulation panels with predefined slots or pre-embedded support clips may employ known wall stud spacing values such as 16-inch or 24-inch, or for example employ 8-inch slot spacing from which the installer can choose to insert the sets of clips at 16-inch or 24-inch intervals according the regional standards or particular job requirements. The insulation panels may vary in size, and accordingly the number of slots or clip sets per panel may accordingly vary.
With reference to FIG. 2, in preferred embodiments, upper and lower foam gaskets 60, 62 are preferably employed between the top edges of the insulation panels 12 and the overhead ceiling or floor joists 50, and between the bottom edges of the insulation panels 12 and the underlying floor, which reduce the effects of floor heaving. The width dimension of each gasket 60, 62, measured perpendicularly from the interior surface of the foundation wall 100 exceeds the combined thickness of the insulation panels 12 and the air gap G measured in this same direction. As a result, the upper and lower framing connectors 48, 56 are fastened to the joists 50 and floor through the upper and lower gaskets 60, 62, respectively, and the top and bottom of the air gap G are sealed off by the gaskets. The gaskets preferably have the same reflective coating as the insulation panels. The gaskets reduce convection flow in the air cavity, which in conjunction with the reflective surfaces, enhances the overall effective R-value significantly.
Although the illustrated embodiment is described as a concrete insulation system installed on the interior of a concrete wall, the insulating wall assembly may be installed in other contexts, regardless of the presence of a concrete wall. In one embodiment, where the insulation panels do not internally line a concrete wall or other structure, the insulation panels may be installed with the slotted-faces of the insulation panels facing outwardly away from the interior space of the building toward the exterior environment. This way, the installation of the framing member support clips and associated framing members on the exterior side of the insulation panels can be used to form a rainscreen, where the slotted exterior face (preferably coated in the manner described herein above) forms a drainage plane, and the support clips and installed framing members create an airspace between the drainage plane and one or more exterior finishing layers mounted on the framing members. Accordingly, the slotted first faces of the insulation panels may face into the interior space of the building, as in the illustrated embodiment, or may face away from the interior space of the building in other embodiments. Likewise, the wall finishing panels may be interior finishing panels such as drywall, or exterior panels such as exterior sheathing onto which additional exterior finishing layers (e.g. siding) can be mounted. Alternatively, wall finishing panels for exterior applications may be the actual finishing layer material itself, it if is suitable for mounting directly to the framing members without an underlying layer of sheathing material.
Since various modifications can be made in my invention as herein above described, and many apparently widely different embodiments of same made within the scope of the claims without departure from such scope, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense.
