Abstract
The present invention relates to a substrate carrying a multilayer solar control stack, as well as to a multiple glazing incorporating at least one such sheet of glassy material carrying a solar control stack. The multilayer solar control stack comprises three functional layers based on a material which reflects infrared radiation and four dielectric coatings such that each functional layer is surrounded by dielectric coating. The geometrical thickness of the second functional layer starting from the substrate is less by at least 4% than the geometrical thicknesses of the first and third functional layers. The invention applies particularly to the formation of high-selectivity solar control glazings.
