CROSS REFERENCE TO RELATED APPLICATIONS 
       [0001]    This continuation-in-part application is related to non-provisional application Ser. No. 13/208,383 filed on Aug. 12, 2011 and provisional application Ser. No. 61/434,870 filed Oct. 21, 2011 both hereby incorporated in full by reference. 
     
    
     FIELD OF INVENTION 
       [0002]    The present invention is in the technical field of insulated wall systems. More particularly, the present invention relates to insulated wall systems using PVC channels for support of horizontal insulated panels on a wall. 
       BACKGROUND 
       [0003]    Finished or “club” basements are a common part of residential structures. Conventional wood framing has been widely used to achieve a finished wall surface. Recently the developments of other innovative wall finishing systems have emerged. These systems are comprised of “shape-molded” insulation panels such as: In-So-Fast™; R-Retro™; Re-Fit and BuildLock™. There is a need for a system that addresses the need for full length synthetic wall channels that can easily accept readily available insulation materials. This approach will allow the unskilled novice to now easily install a finished wall system. Moreover, the locally available sourced insulation material will reduce the need to ship product long distances resulting in a reduction of “carbon footprint”. An earlier embodiment of the insulated wall system described herein used “vertical floor to ceiling panels. While this embodiment satisfied many of the advantages of a needed wall system, there was a need for less expensive and easier to install system. This earlier embodiment is describe in US Patent Publication 2012-0186178, from patent application Ser. No. 13/208,383 filed on Aug. 12, 2011 by the instant inventor and entitled “Wall Insulation System And A Method Of Installing The Same” and hereby incorporated fully herein by reference. 
         [0004]    The presently available systems all require specially shape molded foam insulation elements, they do not create an air space for moisture protection, and/or lack electrical wire chases. 
       SUMMARY 
       [0005]    The new multi-purpose design was developed to better value engineer the part while enhancing the installation process. This new design provides an approximate material savings 38% which will result in a more economical part as well as more efficient shipping. 
         [0006]    The new design was created to allow the system to be installed in a horizontal position and to eliminate several timely steps that were present with the previous design approach which showed a vertical installation of the system. A horizontal installation eliminates the timely corner assembly that is required in a vertically installed application; it also eliminates the need for the “foam filler” in the corner. The channel profiles in a horizontal installation simply “butt-together” perpendicular at the corners. Moreover, the horizontal installation allows the foam to be removed or inserted after the channel is attached to wall surface. This feature is particularly important when addressing the need to install electrical wiring, the foam panel(s) may simply be “popped-out” to install electrical wiring and then “popped” back into place after the electrical wiring is installed. The new channel profile is designed with a “short-lip” that allows the foam panels to snap in and out of place with little effort. Also, the channel profile that was shown in the vertical assemble as a “corner channel” is now used as a “multi-purpose channel” off the concrete floor and is also used to “cap” the system at the top of the wall. More importantly, the “cap” feature of installation process creates a “thermal stop” as well as a “fire-stop” at the top edge of the last panel. The design of the “stud channel” is such that the longer base flange is where a mechanical fastener will secure the channel to the wall. If the installer tries to install the “stud channel” in an incorrect way he/she will know immediately to correct the positioning as they will not have a flange to secure a fastener through. This design feature will drastically mitigate the likelihood of subsequent channel being improperly positioned (mistake caught in the very beginning instead of the very end). 
         [0007]    The embodiments of the invention include a system retrofitting for the insulation of existing interior walls such as basements; a system for retrofitting for the insulation of exterior walls of a structure such as a home or commercial structure needing further insulation without a convenient or an economical method to do so within a system for the inclusion of insulation. The insulated wall systems of these embodiments provide an economical and efficient method of providing the installation of insulation panels to each of the walls described. The horizontally positioned insulation panels are generally of a foam structure supported by connecting and/or horizontal multi-purpose channels. 
         [0008]    The horizontal connecting channels and horizontal multi-purpose channels are of a unique design that are easily fastened to an existing interior or exterior wall. In addition to supporting the insulation panels, the channels are structured to provide a moisture gap between the insulation and the existing wall to which they are mounted. The horizontal connecting channel and horizontal multi-purpose channels also provide for wire chase areas for power distribution within a wall system. 
         [0009]    Since the insulation panels are commercially available throughout the world, the major elements of the system, the connecting channels and the multi-purpose channels are made available as kits to be combined with the Insulation panels that are locally available. This makes is possible for the system to be available to home owners by purchasing the kits and combining them with the locally available Insulation panels. The installation of insulated wall system onto an existing basement interior wall or an exterior home or commercial structure wall requires no special tools and can be done by individuals with minimum construction skills. 
         [0010]    The embodiments described below include details of the horizontal connecting channels and the horizontal multi-purpose channels and their relationship with the insulation panels; and the details of an interior wall installation. 
         [0011]    While the horizontal connecting channels and horizontal multi-purpose channels have been designed for the embodiments described above there are likely embodiments beyond those described herein where this unique design would be applicable. 
         [0012]    For the purpose of clarity, it will understand that all instances of the use of the terms, connecting channel, multi-purpose channel and rigid insulated foam panel will mean horizontal or vertical connecting channel, horizontal or vertical multi-purpose channel and horizontal or vertical rigid insulated foam panel unless otherwise indicated.

     DETAILED DESCRIPTION 
       [0025]    This disclosure discloses an improved insulated wall system. The system in the parent application, Ser. No. 13/106,819 (&#39;819) entitled “Wall Insulation System and a Method Of Installing The Same” is and remains a viable option for an insulated wall system, a tilt up system and a “cast” system. Even though the &#39;819 application may use either horizontal or vertical channel(s) for an insulated wall system a uniquely horizontal system is described herein. The &#39;819 application is hereby is fully incorporated herein by reference. The instant application discloses an insulated wall system with a new channel/stud design that was developed to better value engineer the part while enhancing the installation process. This new design provides an approximate material savings of 38% which will result in a more economical part as well as more efficient shipping. 
         [0026]    The instant design was created to allow the system to be installed with its primary elements to be installed in a horizontal position and to eliminate several timely steps that were present with the previous design approach which created a vertical installation of the system. A horizontal installation format eliminates the time consuming corner assembly that is required in a vertically installed application. It also eliminates the need for the “foam filler” in the corner used in the parent application design. The channel profiles in a horizontal installation simply “butt-together” perpendicularly at the corners. Moreover, the horizontal installation allows the insulating foam to be removed or inserted after the channel is attached to wall surface. This feature is particularly important when addressing the need to install electrical wiring, the insulating foam panel(s) may simply be “popped-out” to install electrical wiring and then “popped” back into place after the electrical wiring is installed. The improved channel profile is designed with a “short-lip” that allows the insulating foam panels to snap in and out of place with little effort. Also, the channel profile that was shown in the vertical assembly as a “corner channel” of the parent design is now used as a “multi-purpose channel” at the floor level and is also used to “cap” the system at the top of the wall. More importantly, the “cap” feature of the installation process creates a “thermal stop” as well as a “fire-stop” at the top edge of the last panel. The design of the “stud channel” is such that the longer base flange is where a mechanical fastener will secure the channel to the wall. If the installer tries to install the “channel/stud” in an incorrect way he/she will know immediately to correct the positioning as they will not have a flange to secure a fastener through. This design feature will drastically mitigate the likelihood of subsequent channel being improperly positioned (mistake caught in the very beginning instead of the very end). 
         [0027]    The details of the elements of the system and installation description are described below. 
         [0028]      FIG. 1  illustrates a wall system  100  with: three walls  102 ,  104  and  106 ; an inside corner  108  and an outside corner  110  with an insulated wall system only installed on a first wall  102  of the three connecting walls  102 ,  104  and  106 . The second wall  104  illustrates the installation of the insulated wall system  100  around a window  112 . The third wall  106  illustrates the installation of the insulated wall system  100  around a door  114 . The Insulated Wall system  100  includes a plurality of connecting channels (CC)  116 , a plurality of multi-purpose channels (MPC)  118  and a plurality of rigid insulation foam panels (RIFP)  120 . Details of the installation process will be discussed below. 
         [0029]      FIG. 2(   a ) illustrates the profile of a connecting channel  116 . The functions of the connecting channel are: provide support for a pair of insulating foam panels  120 ; provide for a CC wire chase area  122 ; and provide for moisture protection of the rigid insulation foam panels  116 . The elements of a connecting channel  116  include: a CC base flange  124 ; a CC supporting leg  126  coupled on a first end to the connecting channel base flange  124 ; a pair of CC interior insulation foam panels support flanges  128  and  130 , each coupled to an opposite side of the support leg  126  and near the CC base flange  124 ; a CC exterior insulation foam panel support element  132  coupled to the support leg  126  having a first portion  134  parallel to the connecting channel base flange  124  and having a second portion extending past the support leg  126  being a “short lip”  136 ; and a rectangular shaped CC wire chase area  122  made up of: a first portion of the base flange  138 , a bottom portion of the supporting leg  140 , a portion of the second (right hand)  130  CC interior insulating panel element that is parallel to the base flange  124 ; and a fourth element  144  coupled on a first end to an end of the second  142  (right handed) portion of the interior insulating team support element parallel to the base flange  124 . 
         [0030]    The shape and some of the dimensions of the connecting channel  116  are dependent upon the thickness of the rigid insulation foam panels  120 . The dimensions discussed below are based upon an insulating foam panel  120  that is 2.00 inches thick and are approximate.  FIG. 2(   b ) illustrates exemplary dimensions for the connecting channel  116 . The CC base flange  124  is 1.74 inches. The CC support leg  126  is 3.00 inches. Of those 3.00 inches, the area supporting a CC rigid insulated foam panel  120  is 2.00 inches. The two CC interior rigid insulation foam panel support elements are a total of 1.55 inches of which 0.80 inch is for the first portion  134  and 0.75 inch for the second portion  136 . The CC exterior rigid insulated foam panel support flange  126  and its “short lip portion  138  is a total of 1.55 inches of which 0.13 inch represents the “short lip” portion  138 . The CC wire chase area  122  is 0.24 inch wide and 0.91 inch high. The thickness of the elements of the connecting channel  116  is 0.09 inch. 
         [0031]      FIG. 3(   a ) illustrates the profile of a multi-purpose channel (MPC)  118 . The functions of the multi-purpose channel  116  are: provide support for a rigid insulation foam panel  118 ; provide for a MPC wire chase area  146 ; and provide for moisture protection of the plurality of rigid insulation foam panels  118 . The elements of a multi-purpose channel  116  include a MPC base flange  148 ; a MPC support leg  150 ; a MPC interior insulating foam panel support element  152  fixed to the support leg  150  and near and parallel to the MPC base flange  148 ; a MPC exterior insulating foam panel support element  154  coupled to the MPC supporting leg  150  and parallel to the MPC base flange  148 ; and a rectangular MPC wire chase area  146  made up of a portion  158  of the MPC base flange  148 ; a lower portion of the MPC supporting leg  156 ; the interior rigid insulation panel element  152  and a fourth element  160  coupled on a first end to an end of the MPC interior insulating foam support element  152  and on the second end to the MPC base flange  148 . The shape and some of the dimensions of the multi-purpose channel  114  are dependent upon the thickness of insulating foam panels  116 . The shape of multi-purpose channel and the dimensions discussed below are based upon an insulating foam panel that is 2.00 inches thick. The principal difference between the connector channel and the multi-purpose channel is that the elements of the connector channel on the side opposite the wire chase area do not exist in the multi-purpose channel. This feature difference permits the multi-purpose channel to be used on the borders such as the top and the bottom of insulated panel system and with interfaces with a window or a door. 
         [0032]    The shape and some of the dimensions of the multi-purpose channel (MPC)  116  are dependent upon the thickness of insulating foam panels  118 . The dimensions discussed below are based upon an insulating foam panel  116  that is 2.00 inches thick and are approximate.  FIG. 3(   b ) illustrates exemplary dimensions for the multi-purpose channel  116 . The MPC base flange  148  is 1.72 inches. The MPC support leg  150  is 3.00 inches. Of the 3.00 inches, the area supporting an insulated foam panel  118  is 2.00 inches. The MPC interior rigid insulation foam panel support element  152  is 1.00 inches. The MPC exterior insulated foam panel support flange  154  is 1.25 inches. The wire chase area is 0.63 inch wide and 0.0.84 inch high. The thickness of the elements of connecting channel is 0.09 inch. 
         [0033]      FIG. 4  illustrates the placement of the elements of an Insulated Wall System in the most basic configuration, one portion of a wall without and any end corners, windows or doors. The order of placement will be discussed further Installation Description portion below. A typical installation as illustrated in  FIG. 4  has two multipurpose channels  116  and a plurality of connecting channels  116 . A first multi-purpose channel  118  is located at the floor level (bottom of the wall) and supports a first layer of insulated foam panels  120 . At this floor level multi-purpose channel  118  has the MPC base flange  148  of the multi-purpose channel  118  facing the wall with the MPC wire chase area  146  facing downward and butting against the floor. The second multi-purpose channel  118  is located at the ceiling level (top of the wall). With this ceiling level multi-purpose channel  118 , the MPC base flange  148  of the channel is facing the wall with the MPC wire chase area  146  is facing upward and is butting against the ceiling. 
         [0034]    The plurality of connecting channels  116  provide support for most of the plurality of layers of rigid insulation foam panels  120  between the two multi-purpose channels  116 . These connecting channels  116  always have the base channel always facing the wall with the CC wire chase area  122  being in a lower part of the mounted connecting channel  116 . The upward side of the CC supporting leg has the larger portion  134  of the exterior insulating panel support element and an upper portion of the interior rigid insulating panel support element  128  providing support for an upper insulating support panel. The lower side of the exterior rigid insulating foam panel support element  136  contains the “short lip” portion The lower portion of the interior rigid insulation foam panel support element  130  and the “short lip”  136  provides the snap ability of installing a rigid insulating foam panel. The installation discussion below will illustrate the reasons for these differences between the differences between the connecting channels and the multi-purpose channels. 
       Installation Description 
       [0035]    Installation of an Insulated Wall System  100  is straight forward and economical if done in a systematic fashion. The tools and hardware need for such system include: Safety goggles; a plurality of 3/16″×1.00 masonry screws; construction adhesive; a plastic pipe saw or similar saw; a hammer drill; a level and square; a tape measure; a chalk-box; a utility knife; a plurality of rigid insulation panels; a plurality of connecting channels; and a plurality of multi-purpose channels. The first step of installing an Insulated Wall System (System) to an (concrete or CMU) existing wall is to remove all dust, dirt, and loose debris from the existing wall to which the System  100  will be applied. The skill level required is the skill by a competent home repair individual. 
         [0036]      FIG. 5  illustrates the first step in the installation of an insulated wall system on a pair of walls  162  and  164  with an inside corner  166  between them. The installation is started by positioning a first multi-purpose channel  116  at the base of a first wall  162 . The multi-purpose channel  116  is positioned up-against the bottom of the first wall  162  and starts by being held tight into the interior corner with the second wall  164 . A second multi-purpose channel  1146  is positioned similarly on the adjacent wall (second wall)  164  and is allowed to “butt” into first multi-purpose channel  114 . A plurality of multi-purpose channels(s)  114  are installed end-to-end around the perimeter of the wells. Adhesive is used to hold each horizontal multi-purpose channel against wall surfaces and on onto floor surface  168 . Mechanical fasteners such as Tap-Con screws and masonry nails may also be used to secure the multi-purpose channels to the first and second walls  162  and  164 . A plurality of multi-purpose channel(s)  118  are placed around the perimeter of walls  162  and  164  end-to-end to create a continuous application of multi-purpose channels that are fastened to the floor  166  using the described methods. This completes a first and bottom multi-purpose layer of multi-purpose channels  118 . 
         [0037]      FIG. 6  illustrates one or more rigid insulation panel(s)  120  being set into the plurality of multi-purpose channel(s) to begin the first layer of insulation. A plurality of rigid insulation foam panels  116  are placed around the perimeter of walls  162  and  164  end-to-end to create a continuous application of rigid insulation. 
         [0038]    Next, as illustrated in  FIG. 7 , the plurality of connecting channels(s)  116  are now installed onto the top edge of the first layer of installed rigid insulation panel(s)  120 . A first connector channel  116  is held tightly into the interior corner just as the first multi-purpose channel  116  was installed on the first wall  162 . A second connector channel  118  is installed on the adjacent wall (second wall)  164  and is “butted” into the first installed connector channel  116 . A plurality of connector channels  116  are subsequently installed end-to-end around the perimeter of each wall  162  and  164  and. The connector channels  116  may only be installed in one position. Due to its unique shape: a connector channel  116  has a single “base flange”  124  that mechanical fasteners must pass through in order to secure the horizontal connector stud to the wall. Therefore, the installer is sure to install it correctly. As illustrated in  FIG. 8  the steps as described in  FIG. 7  will continue until the last layer of rigid insulation foam panels  120  of the system is at top of wall height. 
         [0039]      FIG. 9  illustrates that the last layer of rigid installation foam panels  116  is “capped” using a layer of a plurality of multi-purpose channels  118  which are positioned flush with the top of the walls  160  and  162  with the MPC base flange  148  fastened to the walls and the MPC wire chase area  146  facing downward. Adhesives and mechanical fasteners are also used to secure the top of wall multi-purpose channel to the wall. While standard sizes of the rigid insulation panels and standard length of connecting channels and multi-purpose channels, due dimensional limitation of the wall(s) to which an insulated wall system, cutting to fit may be required. 
         [0040]    With the completion with the installation of the insulated wall system  100  as described above, a layer of finish board materials such as sheet rock can be installed over the insulated wall system. 
         [0041]      FIGS. 10 through 15  illustrate the procedures for installing an Insulated Wall System  200 : around an outside corner  202 ; around a window opening  204 ; around an inside corner;  206 ; and around a door opening  208  on three walls  210 ,  212 , and  214 . 
         [0042]    Installation of the insulated wall system  200  around an outside corner  202  follows a procedure that is described in the parent application with regard to vertical channels used there.  FIG. 10  illustrates the first step in the installation of an insulated wall system on a pair of walls  210  and  212  with an outside corner  202  between them. The installation is started by positioning a first multi-purpose channel  118  at the outside corner  202  of the second wall  214 . The base flange  124  of the multi-purpose channel  118  is fastened to the outside corner  202  end of wall  2   212  with the MPC wire chase  146  end of the MPC base flange  148  flush with end outside corner of wall  2   212 . The MPC base flange  148  of a second multi-purpose channel  118  is positioned up-against the MPC base flange  148  of the first multi-purpose channel with the two base flanges coincident, but the wire chase area not coincident. This arrangement provides a corner support for a plurality of rigid foam panels  120  to be installed later. 
         [0043]    The installation of an insulated wall system around windows and doors follows similar steps as above and in the parent application.  FIG. 10  illustrates the first steps for installing an insulated wall system  200  around window openings and door openings. 
         [0044]      FIG. 10  illustrates an existing window opening  204  on wall  2   212 . The first steps are to prepare the upper and lower horizontal edges of the window opening  204  with the installation of a pair multi-purpose channels  118 . The upper horizontal edge of the window opening  204  has a first multi-purpose channel  118  installed sued that its MPC base flange  148  is positioned against wall  2   212  such that an open side of the MPC support leg  150  is facing downward and the MPC exterior rigid insulation support flange  154  and the interior rigid insulation support flange  152  are facing upward to support a rigid insulation foam panel  120 . 
         [0045]    The lower horizontal edge of the window opening has a second multi-purpose channel  118  installed such that its base flange MPC base flange  148  is positioned such that an open side of the MPC support leg  150  is facing upward and the exterior rigid insulation support flange  150  and the interior rigid insulation support flange  152  are facing downward to support a rigid insulation panel  120 . 
         [0046]    The left vertical edge of window opening has a third multi-purpose channel  118  installed such that its MPC base flange  148  is positioned such that an open side of the support leg  150  is facing rightward and the exterior rigid insulation support element  154  and the MPC interior rigid insulation support element  152  are facing leftward to support a rigid insulation panel  120 . This is an example of a multi-purpose channel being mounted in a vertical direction. 
         [0047]    The right vertical edge has a fourth multi-purpose channel  118  installed such that its MPC base flange  148  is positioned such that an open side of the MPC support leg  150  is facing rightward and the exterior rigid insulation support element  154  and the MPC interior rigid insulation support flange  152  are facing leftward to support a rigid insulation panel  120 . This is a second example of a multi-purpose channel being mounted in a vertical direction. 
         [0048]      FIG. 10  illustrates an existing door opening  208  on wall  3   214 . The first step is to prepare the upper horizontal edge of the door opening  208  with the installation of a multi-purpose channel  118 . 
         [0049]    The upper horizontal edge of the door opening  208  has a first multi-purpose channel  118  installed such that its MPC base flange  148  is positioned such that an open side of the MPC support leg  150  is facing downward and the MPC exterior rigid insulation support flange  154  and the MPC interior rigid insulation support flange  124  are facing upward to support a rigid insulation panel  120 . 
         [0050]    The left vertical edge of the door opening  208  has a second multi-purpose channel  118  installed such that its MPC base flange  148  is positioned such that an open side of the support leg  150  is facing rightward and the MPC exterior rigid insulation support flange  154  and the MPC interior rigid insulation support flange  152  are facing leftward to support a rigid insulation panel  120 . This is a third example of a multi-purpose channel being mounted in a vertical direction.

Summary:
The embodiments of the invention includes a retrofitting system for the insulation of existing interior walls such as basements; a retrofitting system for the insulation of exterior walls of a structure such as a home needing further insulation without a convenient or economical method to do so within the interior walls. The insulated wall systems of those embodiments provide an economical and efficient method of providing the installation of insulation panels to each of the walls described. The insulation panels are generally of a foam structure supported by horizontal connecting and/or horizontal multi-purpose channels. The horizontal connecting channels and horizontal multi-purpose channels are of a unique design that are easily fastened to an existing wall. In addition to supporting the insulation panels, the channels are structured to provide a moisture gap between the insulation and the existing wall to which they are mounted. The horizontal connecting channels and horizontal multi-purpose channels also provide for wire chase areas for power distribution with a wall system.
