Abstract
The invention is a transparent substrate provided with a multilayer stack having thermal properties, especially solar-control or low-emissivity properties. The stack comprises at least one silver-based functional layer surrounded by at least two coatings made of dielectric material, with the presence of thin metal layers between the functional layer and at least one of the coatings made of dielectric material. A preferred stack is D /ZnO/Ag/AlM/D /ZnM′O, with AlM representing an aluminum alloy, ZnM′O a mixed oxide of zinc and at least one other metal, with D and D being a layer or a superposition of layers comprising at least one layer made of a metal oxide, silicon nitride, metal nitride or made of a mixed silicon/metal nitride.
