Abstract
The window covering and shade panel comprise a head rail that supports a shade panel and that may be mounted to a wall, window frame, door or other architectural feature. A layer of film is used with the panel to provide a barrier to air flow and heat insulation. The film may be clear to allow light to penetrate the panel. The clear film allows the heat energy of the sun to pass through the panel while blocking cold air from entering the room. In one embodiment a polyester clear film is chemically adhered to the panel.
