Abstract
An insulated welded wire structural building panel and a method for making such panels are disclosed. The panel has a plurality of parallel trusses joined together with cross wires. Each truss is triangular in cross section. A layer of polyurethane foam is provided in the panel spaced from both the front side and the back side of the panel. On one surface of the foam is a layer of solidified viscous material, such as asphalt or a thermoplastic. The cross wires on opposite sides of the panel are offset from each other along the axes of the truss runner wires to which they are welded.
