Abstract
A building panel has an expanded plastic core with thin reinforcing strips bonded to front and back surfaces of the core, at least along the edges thereof, and may have a wire grid attached in offset relation to one surface thereof for receiving a material such as concrete. The panel is manufactured by a process of expanding a plastic material in a mold by the application of heat to form a core, removing the core from the mold, placing thin reinforcing strips on front and back surfaces of the core with an adhesive system between strips and core, returning the core to the mold and heating the interior of the mold to bond the strips to the core and achieve dimensional stability during molding.
