Abstract
A multiple glazing comprising at least two substrates, one substrate being coated on an inner face in contact with a gas-filled cavity with a thin-film multilayer coating having reflection properties in the infrared and/or in solar radiation, said coating comprising a single metallic functional layer and two dielectric films, said films each comprising at least one dielectric layer, said functional layer being placed between the two dielectric films, characterized in that at least one dielectric film, or both dielectric films, includes an absorbent layer which is placed in the dielectric film between two dielectric layers, the absorbent material of the absorbent layer(s) being predominantly in the dielectric film subjacent to the metallic functional layer or predominantly in the dielectric film superjacent to the metallic functional layer.
