Abstract:
1. An insulated overhead door that is designed to roll open and closed in tracks to cover a door opening having a top and a bottom, the insulating overhead door having a first outermost surface, a second outermost surface opposite the first outermost surface, a top surface, a bottom surface, a first side surface and a second side surface, both the first outermost surface and the second outermost surface being larger than any of the top surface, bottom surface, first side surface and second side surface, the door comprising: a thermoplastic membrane comprising glass fibers and having a top side corresponding to the top of the door opening and a bottom side corresponding to the bottom of the door opening, the thermoplastic membrane forming the first outermost surface of the door; a sheet of foam insulating material directly attached to the thermoplastic membrane, the insulating material extending continuously from the top side to the bottom side of the thermoplastic membrane, the thermoplastic membrane and insulating material forming a panel that is approximately the size of the door opening to be covered, a length of the panel being the distance between the top side and the bottom side, the foam insulating material forming the second outermost surface of the door; and wheels attached to the door allowing the door to fit into tracks to guide the opening and closing of the door, wherein the overhead door comprises only one of the panel, the panel being flexible along the entire length of the panel so as to be capable of approximating the curvature of curved tracks having a radius of curvature ranging from about 5 inches to about 25 inches, where the track has a first length positioned at an angle, Θ, relative to a track portion of a second length, wherein Θ ranges from about 80° to about 125°.
