Description
-- 2~`~4162 TECHNICAL FIELD
This invention relates to a composite insulated gypsum wallboard and system for securing same spaced from a wall to be insulated thereby, such as a concrete basement wall of a building structure. The method of constructing an insulated wall over a concrete basement wall is also described.
BACKGROUND ART
There are various methods used to insulate the inside face of concrete basement walls of building structures, with such methods including securing a solid insulating foam sheet directly on the concrete inside surface in the area which extends above the external ground surface. The foam sheet may also extend to the basement floor. However, in order to secure a finishing wall over the insulated sheet, it is necessary to secure to the concrete wooden or metal studs to attach the facing material over the insulated foam sheet. Accordingly, it is the practice to secure studs directly to the concrete wall and to insulate with the foam sheets between the studs. These nailing studs can be disposed either horizontally or vertically, or both, and usually spaced apart a distance of 4 feet. It is now possible to secure a finishing material over the foam insulators.
A disadvantage of the above method of insulating concrete walls is that, because nailing studs are in direct contact with the concrete wall, it acts as a thermal conductor and affects the insulating properties of the structure. Furthermore, such a method is time consuming and the insulating R-value of the structure is weak. Also, when securing gypsum wallboards over these structures, it is necessary to drive screws therein all along the securement studs. It is then necessary to joint the wallboards and plaster around 2094~6~
the screw heads and taped board joints, as is conventional in the trade.
SUMMARY OF INVENTION
It is a feature of the present invention to provide a composite insulated gypsum wallboard for use in insulating concrete basement walls of building structures, and which substantially overcomes the above-mentioned disadvantages of the prior art.
Another feature of the present invention is to provide a composite insulated gypsum wallboard for use in a wall system having connector strips for securing the insulated gypsum wallboards spaced a predetermined distance in front of a concrete wall to be insulated thereby.
Another feature of the present invention is to provide a composite insulated gypsum wallboard formed from a gypsum board having a sheet of insulating material bonded to a rear face thereof to obtain a desired R-value and wherein the board is spaced from a concrete basement wall of a building structure so that the board, together with the air gap between the board and the wall, constitute an improved thermal barrier to insulate the basement wall.
According to the above features, from a broad aspect, the present invention provides a composite insulated gypsum wallboard for securement from opposed top and bottom end edges and spaced from a wall to be insulated thereby. The wallboard comprises a rectangular gypsum board having a rectangular sheet of insulating material bonded to a rear face thereof. A
securement connector strip is provided for securing a top and a bottom edge portion of the wallboard thereto and for maintaining the wallboard secured and spaced in front of the wall to be insulated, with the insulated material facing the wall. A vertical edge -`` 2094162 interconnecting strip is also provided to interconnect adjacent wallboards together.
According to a further broad aspect of the present invention there is provided a method of constructing insulated walls over concrete basement walls of building structures. The method comprises constructing composite insulated gypsum wallboards by bonding a sheet of insulating material to a rear face of the gypsum wallboards. A ceiling connecting strip having a connector channel is secured to a sealing structure adjacent a concrete basement wall to be insulated and spaced therefrom. A floor connector strip, also having a connector channel, is secured to a floor adjacent a concrete basement wall to be insulated with the floor connector strip disposed in a common vertical plane with the ceiling connector strip, and the channels aligned in facing relationship. One or more wallboards are slid between the channels in close fit therein.
The wallboards are then secured to the channels.

DESCRIPTION OF PREFERRED EMBODIMENTS ~ -Referring now to the drawings, and more particularly to Figures 1 and 2, there is shown -~
generally at 10 the composite insulated gypsum -wallboard of the present invention, and comprised of a rectangular sheet of gypsum board 11 having a rectangular sheet of insulating material 12 bonded to a rear face 13 of the gypsum board 11. The insulating ~ -material sheet 12 is a rigid insulated foam material ~
which is glued to the rear face 13 of the gypsum board, -and has a thickness dependent on the desired insulating ~-R-value of the composite wallboard. The insulating sheet material 12 may be a plastics material, such as polystyrene, polyurethane, phenolic foam, or may be constituted by a sheet of cellulosic fibers, or a sheet having thermal as well as sound insulating properties.
Many other rigid or semi-rigid insulating materials may be used. --~
As ~hown in Figure 6, the composite insulating -~ ~
gypsum wallboard 10 is for securement from opposed top ;
and bottom end edges 14 and 15, and spaced from a wall ~-16, herein a concrete basement wall of a building structure, to be insulated thereby. An air space 17 is provided between the wallboard 10 and the inner face 18 of a concrete wall 16. The air space 17 provides improved insulation. ~ -'' ~
i, .. . . ..
In order to secure the composite insulating gypsum wallboard 10 in a vertical level plane and spaced from the concrete wall 16, there is provided, as shown in Figures 3 to 5, connector strips. Figure 3 illustrates the construction of the ceiling connector strip 19 and, as herein shown, it is formed from an extrusion of metal or plastics material and is of generally U-shape cross-section to define an attachment base wall 20 and opposed spaced wallboard receiving and connecting transverse flanges 21. Figure 4 illustrates the floor connector strip 22, and it is also formed from an extrusion of like material and is of substantially F-shaped cross-section to define a wallboard receiving channel having a base wall 23 and space connecting transverse flanges 24. The spacing between the flanges 21 and 24 is such as to receive the top and bottom end edges of the wallboard 10 in close sliding fit therein.
The floor connector strip 22 is further provided with a securement flange 25 which extends outwardly of one of the connecting transverse flanges and coplanar with the base wall 23. These connector channels are made of anti-corrosive material to prevent oxidation, as these connectors are usually installed in damp areas.
Figure 5 illustrates the construction of the vertical edge interconnecting strip 26. It is essentially a T-shape strip which is extruded from the same material as the ceiling and floor connector strips 19 and 22. The T-shaped strip defines opposed connecting flanges 27 which extend in planar alignment with one another, and a transverse flat wall 28. The opposed connecting flanges 27 each extend over the exterior face 29 of the sheet of insulating material 12 and along a vertical edge thereof of a respective one of adjacent wallboards 10' and 10", as shown in Figure 7. As also shown in that Figure, the transverse flat wall 28 is disposed between the vertical end edges 29 6 209~162 and 29' of the wallboards 10' and 10" respectively.
Fastener means in the forms of screws 30 are driven from the outer face 31 of the gypsum board 11, through the insulating material 12 and into the connecting flanges 27. Jointing compound 32 and a jointing tape 33 then conceal the joint and the screws, as is well known in the art. This jointing is only effected after the insulating wall has been constructed, and the method of its construction and erection will now be described.
Referring now more particularly to Figure 6, there will be described the method of constructing the insulated composite wall of the present invention and, as herein shown, in order to provide lateral stability to the wall, it is desirable to secure abutment insulating foam blocks or strip 34 to the concrete wall 16 at about mid-height thereof. A caulking compound 35 having insulating properties may be beaded along the outer face of the abutment so that when the sheet is slid between the connector strips 19 and 22, the exterior face 29 of the insulating sheet 12 will set in securement with the strip 34 through this bead of compound. The strip or blocks 34 provide lateral stability to the wall. Of course, other material could be used as spacer means, such as the blocks 34.
Furthermore, the blocks 24 of insulating foam material may be glued to the inner face of the concrete wall or the insulating sheet 12.
The method of constructing the wall 10 consists in securing the ceiling connector strip 19 with its connector channel facing downwardly and spaced a desired predetermined distance from the inner face 18 of a concrete wall. The ceiling connector strip is secured to a ceiling structure, such as floor joists 36, by means of screws or nails 37 and in parallel alignment with the inner face 18 of the concrete wall 7 2094~62 16 to be insulated. The floor connector strip 22 is then secured to the floor surface 38 and in vertical alignment with the ceiling connector strip 19, and its channel facing upwardly. Concrete nails 39 or glue can secure the floor connector strip to the floor surface 38 with the securement flange 25 facing inwardly or outwardly, as shown in Figure 8, of the inner face 18 of the concrete wall. The composite wall boards 10 are then slid from an end of the floor connector channels, which is not installed from wall to wall, and positioned side by side in a common plane. These connector channels 19 and 22 may be extruded in lengths of 8 to 12 feet, or any other desired lengths and easily cut with a standard tool, such as a handsaw.
After the first wallboard is slide in between the channels the wallboard is attached to the connector strip 19 and 22 by driving screws 40 through an outer one of the connecting transverse flanges 21 or 24. The T-shape vertical edge interconnecting strip is then secured to adjacent vertical edges of adjacent wallboards. This is done by securing the strip to the firstly placed wallboard 10', as shown in Figure 7, and then sliding the next wallboard 10" in position with the transverse flat wall 28 sandwiched between the end edges 29 and 29' of the wallboards. As herein shown, the transverse flange 28 is shorter than the thickness of the composite wall board to provide a cavity between the wallboard to permit a jointing compound to enter the cavity between the wallboards to provide a more solid joint, as is obvious in the art.
Because the wallboards are slid from an end of the connector strips and in close fit between the connector channels 19 and 22, they provide good insulating property by eliminating air leaks. The end wall panel must be installed differently, because the panels are slid in position from an end of the floor track or strip 22. Accordingly, with the end wall panel a floor connecting strip 22 is cut to the width of the panel and installed thereon with its securement flange 25 extending outwardly, as shown in Figure 8. The top edge of the panel is then fitted in the ceiling connector strip 19 and the panel is aligned with the previously installed panels. A nail or glue secures the floor connector strip in position. It is pointed ;
out that these connector strips are provided of thin web extrusion, and it is therefore possible to easily cover the securement flange 25 when a floor covering, such as a carpet 41, is glued to the floor surface 38 which is usually concrete. -~
It is also appreciated that when openings are to be formed in the wallboards 10, such as window openings, these are cut out from the wallboard and the insulating space 17 between the wallboards and the concrete wall is framed with strips of insulating foam material or nailing studs.
It is within the ambit of the present invention to ~ -cover any obvious modifications of the preferred embodiment described herein, provided such modifications fall within the scope of the appended claims. For example, the strips 19 and 22 may be formed differently, such as with L-shaped channels and may be formed of separated sections to facilitate installation.
