Abstract: Closure panel having high heat insulative capacity. There has been designed for a building opening a closure having a higher heat insulative capacity than has previously been available. There are provided inner and outer panels of high structural strength, such as steel, with means providing for the physical connection with thermal separation thereof. The space between said panels is filled with a foam material, foamed in place, which further provides for the mechanical connection but thermal separation of said inner and outer panels.

Abstract: A jalousie door as described, having sections turnable about horizontal axes, the door being formed by a plurality of upper and lower juxtapositioned sections, each provided with an upper edge portion of a stepwise increasing height extending from the outside to the inside of the door, the side of the step facing outwardly forming a chute shaped cavity which is open outwardly and extending along the respected sections, the upper wall forming the cavity being horizontal when in a closed position.

Abstract: An insulated sectional overhead garage door comprising a plurality of pivotally connected door panels, each having an interior cavity filled with insulating material. Weather stripping is provided between adjacent door panels to prevent heat loss. One feature of the invention pertains to the quick mounting of the rollers to the panels by means of a pair of bushings and a spacer retainer. Another feature pertains to the movable vertical track for retaining the door in the closed position. The track is movable downwardly and toward the door jamb in response to movement of the door to its lowermost position. The upper end of the door is retained in a track having adjustment means for selectively adjusting the distance between the door header and the upper end of the door. The vertical track is movably mounted on an L-shaped frame member constructed of heat insulating material which is securely mounted to the door jamb.

Abstract: Moveable barrier to cover and uncover building window and the like to control thermal energy transmission. Barrier includes group of elongated hollow, slats mounted on tracks and connected by pivots. Slats form generally rectangular shaped moveable panel. Material of tracks and slats and the dead air spaces of slats form thermal barrier. Panel can be moved to cover and uncover area. Pivots provide for panel to be rolled up when moved to the uncover position.

Abstract: An articulated overhead door constructed of blow-molded material sections for use on building structures such as industrial, commercial, and residential garages.

Abstract: An upwardly-acting sectional door composed of a plurality of sections for sliding from a vertical track which aligns the sections in a vertical plane around a curved track to a horizontal track which aligns the sections in a horizontal plane. The sections are hinged together and each section is substantially the same throughout its width or length so that it may be cut off to provide any width door. The sections comprise an extruded or formed foamlike light material of a good heat insulating property which is reinforced at the location that the hinges are placed, and each section has interfitting edges. The sections are finished by face pieces of stiff material that may be adhesively secured to the foam or made integral therewith.

Abstract: A sectional door such as a garage door of the type having a plurality of hingedly connected panels adapted to be pivoted relative to one another generally about interior edges of facing lateral ends during opening and closure of the door. One of each pair of facing ends of the panels is equipped with a first rail having a front wall and defining an interior pocket. The facing end of the adjacent panel is equipped with a second rail having an arcuate segment extending into the pocket of the first rail in overlapping relationship to the front wall thereof when the adjacent panels are in aligned orientation. When the adjacent panels are pivoted relative to one another generally about their interior edges, the arcuate segment of the second rail moves outward of the pocket of the first rail to span the angular gap formed between the facing ends of the adjacent panels.
