1. A process for the manufacture of a glazable, molded panel, door or window which moulding includes, on at least three sides of the area to be glazed, a plastics foam core and one or more continuous, integral skins comprising a synthetic polymer, which process includes:
forming the plastics foam core with a continuous groove in register with the intended position of the glazing, the groove extending along the at least three sides of the area to be glazed;
lining the groove with a layer of a synthetic polymer which may be the same as or different from the skin polymer(s), the layer being at least partly contiguous with the or each skin;
slidably inserting a former into the groove wherein the former and the glazing are inserted through a slot in the plastics foam which co-operates with the groove; and
moulding the panel, door or window with the application of heat and pressure thereby bonding the layer of synthetic polymer to the or each skin to form a continuous, integral skin of a synthetic polymer about the at least three sides of the area to be glazed.
