Abstract:
An insulated wall system, comprising:a concrete wall; an insulated layer fixed to the concrete wall and comprising a plurality of insulated panels disposed adjacent to each other, each of the panels comprising a core of rigid foam, and at least two reinforcing strips extending substantially the entire length of the panel; a plurality of fasteners to retain the insulated panels to the concrete wall, wherein the fasteners have a shank, and the shank extends through the insulated panel and through the reinforcing strips and thence into the wall where it is anchored; and a wallboard layer fixed to the reinforcing strips of the insulated layer, wherein each of the insulated panels of the wall system further comprises a first reinforcing layer that is bonded to a first planar surface of the core of its corresponding panel and is disposed between the wallboard layer and the core, wherein the at least two reinforcing strips of each insulated panel comprising the insulating layer are substantially parallel to each other and to two opposing edges of each of the panels, and further wherein the plurality of fasteners are driven from an outer surface of the insulated panels, through the first reinforcing layer, then through the reinforcing strips, and then through the core and then into the concrete wall where the plurality of fasteners are anchored.
