ABSTRACT:
A joint structure for connecting framing components such as sash members for a window is disclosed having separate functional and decorative junctions between adjacent framing components. The functional junction between components may be formed between opposing and abutting mitered mating surfaces defined at adjacent ends of the component, and a separate squared flange and cooperative recess may be formed on interior surfaces of the components for overlapping the mating surfaces and providing a decorative junction, for example, having the appearance of a mortise and tenon joint. The joint structure is particularly suited for use in custom or replacement applications whereby lineal extruded members formed of a heat weldable material may be cut to size having the aforementioned surfaces, and then heat welded together to form a custom sized framing structures such as a sash or frame for a window or door.
