Abstract
The present invention relates to solar-control glazings intended to be fitted in buildings, but also in motor vehicles. They comprise a glass substrate carrying a transparent multilayer stack comprising an alternation of n silver-based functional layers that reflect infrared radiation and of n+1 dielectric coatings, with n≥1, such that each functional layer is surrounded by dielectric coating. At least one of the dielectric coatings comprises a substantially metallic solar radiation absorbing layer based on Pd, enclosed between and in contact with two dielectric oxide layers of at least one element selected from Zn, Sn, Al, In, Nb, Ti and Zr.
