Abstract
A multi-pane insulated glass door assembly in which the forward pane of the glass unit extends outwardly a greater distance than the panes rearwardly thereof and is supported by an outer metal frame having a relatively narrow forwardly extending perimeter portion adjacent the peripheral edge of the forward glass pane so as to provide the door with a modernistic, substantially all glass front appearance. In one embodiment, the outer metal frame has a rear portion extending inwardly behind the forward glass pane and a moulding is interposed between the forwardly extending perimeter portion of the metal frame and the peripheral edge of the forward glass pane to provide a finished appearance. A dark ink is affixed to an inside peripheral face of the forward glass pane for masking the peripheral components of the door assembly from sight through the forward glass pane from the front side thereof. In another embodiment, each door has a non-metallic, lightweight outer molded trim portion which encapsulates the outer support frame and the periphery of the glass unit and which has insulating qualities that tends to prevent heat transfer between warm and cold sides of the door.
