Abstract
Abstract A door assembly having compression molded skins and compression molded panel is disclosed. The panel may be molded with one of the skins or molded separately. The surfaces of the panel and a surface of each of the skins have a textured pattern which simulates the grain and texture of a wood door. A core is positioned between said skins. The construction of the skins permits effective introduction of foam to form the core therebetween following assembly of the skins.
