Abstract
A method of forming a prefabricated insulated wall panel for installation with like wall panels for easily and inexpensively building a wall. The method includes the steps of providing a mold for casting a concrete member having a generally planar portion including an inner surface and an outer surface and a plurality of rib portions extending from the inner surface to an edge, nesting at least one insulation strip within a respective spring member so that the spring member extends about sides of the insulation strip and terminates in end portions which extend inwardly relative to the insulation strip sides, selecting the spring member to be biased against respective walls of a mold portion corresponding to a rib portion of the concrete member when the nested insulation strip is inserted therein, inserting the nested insulation strip in the mold portion, and casting the concrete member in the mold with the insulation strip and the spring member unitarily attached to a rib portion edge of the concrete member with the end portions of the spring member anchored in the concrete member to make a wall panel.
