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 at least n functional layers based on a material which reflects infrared radiation and (n+1) transparent dielectric coatings such that each functional layer is surrounded by transparent dielectric coatings, n being greater than or equal to 3. The stack comprises at least one layer of metallic nature absorbing in the radiation which is visible inside the stack. The invention applies particularly to the formation of solar control glazings with low solar factor.
