Description:
TECHNICAL FIELD 
       [0001]    The invention generally relates to wall panels and systems. 
       BACKGROUND 
       [0002]    A typical basement has perimeter walls of poured concrete or blocks which line a hole or cavity excavated into a ground surface and which acts as a foundation for a home or other structure supported thereby. 
         [0003]    Typical perimeter walls are built with load bearing rather than aesthetic aspects in mind and accordingly tend to be somewhat irregular and are generally uninsulated. In order to finish a basement, the foregoing aspects must be dealt with. 
         [0004]    The typical way to finish a basement is to erect “studs” (vertical wooden members) typically spaced 16 inches apart along the interior face of the perimeter walls. Insulation of some form (e.g. Styrofoam™ or fibreglass) is inserted in the channels defined by the wall and the adjacent studs. A suitable vapour barrier is placed over the insulation if required and “drywall” (gypsum wallboard) sheets are secured to the studs over the insulation and vapour barrier. 
         [0005]    The “finishing” of a typical basement using the prior system is labour and time intensive. Typically upper and lower framing members would be installed adjacent respectively the ceiling joist and a floor. Studs would be mounted between the upper and lower members. The insulation would be cut and installed. The drywall sheets would be cut and secured and finally joints between the drywall sheets would be taped and filled with drywall compound for subsequent sanding and final finishing. 
         [0006]    In addition to the above steps, accommodation must be made for electrical sockets and switches. Such would typically be mounted in boxes secured to the studs and serviced by wiring also secured to the studs. Once the boxes have been installed, a challenge is presented to one installing drywall sheets over the boxes in that the location of the boxes has to be carefully measured and translated to the drywall sheet in order to cut suitable openings to accommodate the boxes. 
       SUMMARY

     DETAILED DESCRIPTION 
       [0047]    A modular wall panel according to one embodiment of the present invention is generally illustrated by reference  2 . 
         [0048]    The panel  2 , also referred to as a “light switch panel” if a light switch installed in the panel, is comprised of a sheet  4  of medium-density fiberboard (“MDF”) having an outer wall finishing surface  6  and an interior surface  8 . The sheet  4  is 14 inches wide and 96 inches high but may be of other dimensions depending upon the application. The sheet  4  may be made of other material suitable for forming an interior wall, such as but not limited to gypsum wallboard, shiplap, HDF, OSB, fibre cement board and drywall. The wall finishing surface  6  is one which is suitable for accepting wall finishes such as wallpaper and paint. The surface  6  may be pre-primed such that once installed, it can be painted without further priming. 
         [0049]    Two framing members  10  and  12  are secured to the panel on the interior surface  8  side of the sheet  4 . The framing members  10  and  12  may be secured to the sheet  4  by suitable adhesives or fasteners. The framing members  10  and  12  are at or near the edges of the sheet  4  but may be located at other locations on the sheet  4  provided that the sheet  4  is provided with a sufficient amount of structural integrity. The framing members  10  and  12  are 2′×3′ wood lumber and extend from the top  26  of the sheet  4  to near the bottom edge  27  of the sheet  4 . Recesses  29  are provided between the end of the framing members  10  and  12  and the bottom edge  27  to receive a cleat when the panel  2  is installed on joists provided with a cleat. Recesses  29  are optional and the framing members  10  and  12  may extend to the bottom edge  27 . The framing members  10  and  12  may be of other dimensions and may be made from other suitable materials such as wood-plastic composite materials, metals, alloys and plastics that provide sufficient structural integrity to the sheet  4 . The framing member  10  is provided with a groove  14  while the framing member  12  is provided with a tongue  16 . The groove  14  is for receiving a tongue from another panel while the tongue  16  is designed to be received by a groove in another panel when more than one panel  2  is joined together to form an interior wall or part of an interior wall. Instead of tongue and groove, other suitable connectors, such as a click-lock system, may be provided in the panel  2  for connecting panel  2  to one or more other panels. 
         [0050]    In order to provide electrical or communications service to the panel  2 , a box  18  is provided for housing an electrical or communications outlet (not shown). The electrical or communications outlet includes an electrical outlet, electrical switch, cable box, telephone jack, internet jack, and the like. An opening  20  in the sheet  4  provides access to the box  18 . The box  18  is located in the panel  2  such that upon installation of the panel  2 , the box  18  is at approximately the standard height from the floor that is typical for that type of box. The box  18 , in other embodiments, may be located elsewhere in the panel  2  such that when panel  2  is installed, the box  18  is located at a non-standard height above the floor. In other embodiments the horizontal position of the box  18  in the panel  2  may vary. A tube conduit  22  extends from an opening  24  in the box  18  to the top edge  26  of the panel  2 . The conduit  22  allows for the installation of wiring for wiring an electrical or communications outlet housed in the box  18 . The conduit  22  can be made of PVC or other suitable material. 
         [0051]    Insulation can be placed in the area between the framing members  10  and  12  and around the box  18  and conduit  22  and secured to the sheet  4  and/or the members  10  and  12  by suitable means such as adhesives and fasteners. The insulation can be any insulation suitable for residential or commercial construction to insulate. Examples of insulation which can be used include sheet foam insulation (for example be of Styrofoam™) and fibre glass insulation (for example Fiberglass Pink™). In certain embodiments, the insulation may be secured to the sheet  4  and/or to the members  10  and  12  and/or retained in place by other suitable means such as by a sheet of plastic vapour barrier material, (not shown) or other suitable material secured to the back side of the panel. 
         [0052]    In another embodiment, in the panel  2 , the box  18  and the conduit  22  can be housed in sheet foam insulation  30 .  FIG. 2  is a cross section taken along line A-A of  FIG. 1  of another embodiment (with insulation  30 ) of the panel  2  of  FIG. 1  (panel  2  in  FIGS. 1 ,  3  and  4  is shown without insulation). The insulation  30  may cover all or part of the area of the sheet  4 . In such an embodiment, a well (not shown) is provided in the sheet insulation to house the box  18 . A channel (not shown) is provided in the foam insulation to house the conduit  22 . In a further embodiment, the tube conduit  22  can be omitted and a channel in the insulation  30  can serve as a conduit for wiring. In a still further embodiment, the well in the sheet of insulation is omitted. In such an embodiment, an opening in the sheet  4  and a well in the insulation  30  may be cut such that the cut well is in communication with the conduit  22 . An electrical or communications box may then be inserted into the well. In a still further embodiment, the sheet  4  may be omitted 
         [0053]    The incorporation of an electrical outlet box  18  with an electrical conduit  22  in panel  2  facilitates the installation of electrical or communication services in a finishing operation such as in a basement. Previously, electrical outlet and cable would have been secured to studs prior to placement of drywall over the studs. This proved challenging in guessing with any degree of accuracy where to place a hole in the overlying drywall sheet so as to correspond with the electrical or communications outlet. 
         [0054]    A wall panel according to another embodiment of the present invention is illustrated by reference  40 . The panel  40  is also referred to as an “outlet or cable panel” if an outlet or cable box is installed in the panel.

The plate  222  includes an H-shaped opening  226  which is dimensioned to correspond to size of an opening for a standard electrical or communications box. The template  222  and the opening  226  may be of other shapes and sizes depending upon the application. 
         [0083]    In use, in order to cut an opening in a sheet of material suitable for forming an interior wall  228 , having conduit  230 , the template  222  is positioned such that the flange  224  abuts the side  232  of the sheet  228 . A saw such as a jig saw is used to cut out an opening in the sheet  228  by cutting along the inside edges of the H-shaped opening  226 . 
         [0084]    A series of wall panels according to certain embodiments of the present invention may be joined together to form an interior wall of a basement. The interior wall could equally be in another area of a dwelling or commercial building. The panels are installed against 2×3 cleats  250  and  260  that are fastened to the bottom of floor joists  270  at the top of the wall and to a subfloor system  265  of the basement. The top cleat  250  may be installed first against floor joists  270  and the bottom cleat  260  is then installed offset from the top cleat to accommodate the notch  280  at the bottom of each floor panel. Once the cleats  250  and  260  are installed, one determines which type of panel is required and where, and installation can proceed beginning in a corner of the basement. For walls that require plumbing installation as well, the cavity  272  created behind the wall  273  formed by the panel system and the exterior wall  274  of a dwelling or commercial building, allows for the pre-installation of all plumbing required. Once the plumbing is installed, the wall panels  290 ,  300 ,  310 ,  320  and  330  may be installed. The wall panels  290 ,  300 ,  310 ,  320  and  330  are preferably installed before the ceiling is installed enabling electrical installation to be completed after installation of the wall panels but prior to the installation of the ceiling.
