ABSTRACT:
A foamed plastic core door, structural panel or closure member comprises an inner core of light weight, cellular, foamed plastic material having opposite outwardly facing side surfaces, each formed with a base portion having a plurality of relatively small, integrally formed, outwardly projecting, compressible bosses arranged at spaced apart intervals thereon. At least one outer skin or decorative door face member is provided having an inside surface confronting said core surface in facing spaced apart relation with the base portion and in adhesive contact against the outer faces of a plurality of the projecting bosses, thus, providing a thin, dead air, insulating space between a major area portion of the side face of the core and the adjacent confronting inside surface of the outer skin.
