Abstract
A glass sheet is provided with a coating which will automatically reflect infrared radiation if the ambient temperature is above about 45.degree. F.-60.degree. F. Such a coating is placed on the exterior surface of the glass. Additionally, the interior of the glass may be provided with a controllable infrared transmittable or reflective layer of material which is activated by means of an electric current transmitted therethrough and which will reflect infrared energy if so energized, but otherwise will transmit such infrared energy. This layer of material is preferably placed on the interior of the glass surface and activated during the nighttime period so that infrared energy is not transmitted outwardly. Alternatively, the controllable infrared transmittable or reflective layer of material may be positioned both on the exterior and interior of the glass surface.
