Abstract
Abstract A multi-layered solar heat reflecting glass, comprising one layer of colored glass and two layers of transparent glass bonded together. One surface of the colored glass is provided with a reflective, metallic oxide film. The external surface of the metallic oxide film is then bonded to a layer of transparent glass using a low water content bonding agent such as epoxy resin adhesive. A second layer of transparent glass is bonded to the other surface of the colored glass by means of a second bonding agent capable of preventing shattering. Alternatively, the oxide film and the bonding agent layer are provided between the two layers of transparent glass, with the colored glass being bonded to one of the external surfaces of the transparent glass.
