ABSTRACT:
The invention provides a heat reflecting glass plate with a multilayer coating on a transparent glass plate. The multilayer coating comprises a film of indium-tin oxide (ITO) of Al=N deposited on the glass surface, a heat reflective film of Ag or Cu deposited on the ITO or AlN film to a thickness of 40-200 .ANG., a metal Zn film deposited on the Ag or Cu film to a thickness of 20-200 .ANG. and an ITO or AlN film as the outermost layer. The multilayer coating may further comprise at least one set of the Ag or Cu film, metal Zn film and ITO or AlN film such that each Ag or Cu film overlies an ITO or AlN film and is overlaid with a metal Zn film and that the outermost layer is an ITO or AlN film. The multilayer coating is excellent in the fundamental characteristics as a heat reflecting and transparent coating and also in moisture resistance.
