Abstract
The invention relates to solar-control transparent glazing comprising, on a glass substrate, a transparent multilayer stack including an alternation of n silver-based functional layers and n+1 dielectric coatings, where n≧1, such that each functional layer is surrounded by dielectric coatings, and at least one solar-radiation-absorbing layer enclosed between two dielectric layers formed by a material selected from among aluminum or silicon nitrides or mixtures thereof, inside one of the dielectric coatings. At least one functional layer is disposed on top of the so-called absorbent layer, and an intermediate transparent oxide layer selected from among oxides of zinc, tin, zirconium, titanium or alloys of same and a zinc oxide-based wetting layer are disposed between the absorbent layer and the functional layer, the intermediate transparent oxide layer having a different composition from that of the wetting layer, said wetting layer being immediately next to the functional layer.
