ABSTRACT:
Shaped articles such as doors, internal partitions and other building elements, are composed of a cellular thermoplastic material, and have at least one integral non-cellular transparent or translucent panel. The thermoplastic material is preferably a water-extended polymer, and may contain a colouring agent dispersed therethrough, e.g. a dye or pigment, or may be printed. The panels may be embossed to provide a visible decoration. Compared with equivalent articles having separately glazed panels as previously known, the present integral panels remove the need to fit and secure separate panes, e.g. of glass, during assembly, they provide a more unified appearance, and give designers greater scope in enabling them to incorporate panel shapes which would previously have been impossible or uneconomic to use.
