ABSTRACT:
An improved sectional overhead garage door with an integral automatic opener and closer which comprises a plurality of horizontal sections which are hinged together on opposite sides in alternate fashion and wherein the panels are made strong and light by providing parallel sheets of plastic aluminum or steel which are held along the edges with aluminum extrusions and where the hollow insides of the panels are filled with foam to provide rigidity and strength. The door as it is opened folds up like an accordian with adjacent sections folding back upon themselves so that a very compact unit is provided.
