Abstract
Abstract A safety glass to provide dual heat reflecting layers in a glass sheet unit of laminated structure is composed of a laminate of two transparent glass sheets (1,5), each having a layer of heat reflecting coating or film (3,4), or a heat reflecting layer. The two glass sheets (1,5) are so bonded that the surfaces having the heat reflecting layers (3,4) facing each other, with the layer of bonding material (2) interposed between the two heat reflecting layers. In another preferred embodiment the surface of one (first) glass sheet (1) having the heat reflecting layer (3) is bonded to the opposite surface of another (second) glass sheet (5) to leave the heat reflecting layer (4) of the second glass sheet exposed on the outer side surface.
