Abstract
The invention relates to a multiple glazing including 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, the coating including a metallic functional layer and at least two dielectric films, each including at least one dielectric layer, the metallic functional layer being placed between the two dielectric films, characterized in that the two dielectric films each include at least one absorbent layer which is placed in the dielectric film between two dielectric layers, the absorbent material of the absorbent layers being symmetrically placed on either side of the metallic functional layer.
