  • Patent number: 5277013
    Abstract: The present invention provides a preformed modular wall panel for constructing the exterior walls of a building and a method of assembling such wall panels. The wall panel comprises a rigid frame, a sheet of exterior finishing material attached to the exterior periphery of the frame and a sheet of insulating material held in slots in the frame intermediate the exterior and interior peripheries of the frame. This spaced-apart relationship defines a closed-air space between the exterior sheet and the insulating sheet. A cementitious exterior sheet attaches to the exterior periphery of the frame by a plurality of projections extending from the frame. The projections are embedded in a fluidal cementitious material held in a casting form. The cementitious material cures into a solidified exterior sheet. A method and apparatus for manufacturing the panel and a method and apparatus for erecting a wall of the panels are disclosed.
