Abstract: A door comprises a core comprising a synthetic resin honeycomb core member and a coplanar wood panel along one edge thereof. Front and rear door skins adhere to and sandwich the core. Spaced opposed peripheral edge flanges of the door skins retain a gasket retainer in a peripheral edge slot in the core. A resilient edge gasket extends from the gasket retainer out between the peripheral edge flanges of the door skins. At concentric openings in the core and door skins, the door skins are depressed inboard toward each other to form a common peripheral flange for a window mounting gasket. The method of making the door includes molding the skins and core member from synthetic resin material, slotting the core peripheral edge and inserting the gasket lock member, adhering and pressing the cut skins onto the side-by-side panel and core member forming the core and pressing same together, cutting the window opening and installing the window with its gasket, the hinges, and the edge gasket.

Abstract: Curtain structure for substantially covering the access opening of an open-sided, display-type, refrigerated food cabinet. A first curtain comprises a flexible sheet prestressed to roll up and fixed at its upper edge to the ceiling of the cabinet inboard of the access opening. The first curtain may be unrolled and its bottom edge attached to the floor of the cabinet to substantially block air movement into and out of the cabinet. A second curtain comprises a plurality of side-by-side, elongate strips of flexible transparent sheet material, fixed together at their upper ends and supported on the cabinet at the top of the access opening. The lower ends of the strips are free of each other and terminate slightly above the bottom of the access opening. The second curtain is spaced away from the closed position of the first curtain by an air layer providing a thermal barrier across the access opening when access to the interior of the cabinet is not needed.
