Abstract
A refrigerator door assembly having a door mounting cabinet frame which has a thermally efficient composite design comprising a non-metallic pultrusion-formed structural frame member and an outer metallic trim panel mountable on the structural frame member for providing the desired finished appearance, which may be made consistent with conventional commercial refrigerator and freezer door assemblies. The door mounting frame includes a mullion which also includes a pultrusion formed non-metallic structural element. A rigid plastic molding assembly encompasses the rear and sides of the structural frame members and define air insulating spaces about the frame members. The pultrusion formed frame members permit thermal insulated mounting of metallic accessories by ultrasonic welding methods.
