1 . Field of Invention
The present invention relates to windows and more particularly is directed to a thermal-break window fabricated of a plurality of extruded frame members designed, when interconnected, to form a substantially rectangular frame for encasing a glass panel.
2. Description of the Prior Art
Windows of various configurations have previously been made from a plurality of precut extruded sections that were fastened together by welding and/or by fasteners, e.g., screws, nuts and bolts or the like. All these windows have been suffered from the disadvantages of complex and costly fabrication and assembly techniques. Furthermore, all these prior windows possessed an undesirable characteristic, namely that of conducting heat or cold from the outside atmosphere through their metal frame members into the room, thus not being energy efficient.
