Abstract
A method for making insulated pre-formed wall panels for attachment to like insulated pre-formed wall panels for building a wall. The method includes providing a mold for casting a concrete body having a generally planar portion with a plurality of rib portions extending therefrom, nesting at least one insulation strip within a respective spring member, covering the end portions of the respective spring member with a thermally insulating material to limit thermal conductivity from each respective rib portion of the concrete body to each respective spring member, inserting each respective spring member with the at least one nested insulation strip in the mold, and casting the concrete body in the mold with each respective spring member with the at least one insulation strip being unitarily attached to an edge portion of each respective rib portion with the end portion of each respective spring member being anchored in each respective rib portion of the concrete body to make the insulated pre-formed wall panel. The spring member serves as a nailer strip for the insulated pre-formed wall panel.
