ABSTRACT:
The invention relates to a frame assembly for making double-glazed doors or windows comprising a metal extrusion having a cross-section, preferably an H-section, providing an open channel having oppositely facing abutments along the internal surfaces of the free edges of the channel side walls, a facing strip extruded of a substantially rigid plastics material of a desired color having a profiled rib along its rear face which fits between and interlocks with the abutments to hold the facing strip bridging the channel side walls. The metal extrusion provides the necessary rigidity to a frame as well as a fixing for hinges or hardware, while the inner and/or outer facing strips provide a thermal break between the inner and outer sides of the frame as well as a substantially permanent and weatherproof decorative finish to the frame.
