ABSTRACT:
A sliding glass door assembly comprises a frame of rigid plastic, for example polyvinyl chloride, extruded in the form of a plurality of adjacent hollow sections. The upright and horizontal frame members are attached together by screws extending horizontally through the upright members into longitudinally extending screw bosses in the horizontal frame members. The frame members include depending guides for supporting door panels, at least one of which slides open and closed. The door panels are formed of vertical and horizontal sash members which support at least one, but preferably several, glass panels. The sash members are also formed of plural hollow sections that cooperate for strength, and are attached by screw bosses. Preferably, the screw bosses in the sash of the moveable panel or panels are contained in the upright sash members, and preferably each upright sash member has a pair of screw bosses for attaching not only the lower sash member, but also for attaching roller elements at each end of the moveable sash. The roller elements are supported on a track held in the lower horizontal frame member.
