Abstract
The invention relates to solar control glazing comprising, on at least one of the surfaces of a glass substrate, a system of layers including at least one solar-radiation-absorbing layer and dielectric layers surrounding said solar-radiation-absorbing layer. According to the invention, the solar-radiation-absorbing layer is a metal layer based on tungsten alloyed with at least nickel. The layer system comprises: between the substrate and the metal layer, at least one layer of a dielectric material based on oxide, nitride or oxynitride of silicon or aluminum, or mixed aluminum/silicon nitrides; and, on top of the solar-radiation-absorbing layer, at least one layer of a dielectric material based on one of said compounds.
