ABSTRACT:
Each panel section of a garage door of the articulated type comprises an insulating board of styrofoam, taken in sandwich between two metallic facing sheets, the styrofoam and facing sheets edgewisely carried by a quadrangular tubular frame. The frame is made from extruded tubular sections of plastic, the interior walls thereof being coplanar and flatly edgewisely abutting against the styrofoam boards. A reinforcing metallic frame is mounted within the tubular frame. The tubular frame includes inturned locking flanges at the interior and exterior faces of the panel; at least one locking flange is releasable. The facing sheets and styrofoam boards are held in place by the locking flanges.
