Abstract:
1. A multiple glazing, comprising: a first substrate having a first face that faces an external space and a second face, which is opposite to the first face and faces a gas-filled cavity; a second substrate having a first face that faces the gas-filled cavity and a second face, which is opposite to the first face and faces an internal space; and a frame structure, which holds the first substrate and second substrate together such that the glazing separates the external space from the internal space with the gas-filled cavity lying between the first and second substrates, wherein one of the substrates is coated on an inner face in contact with the gas-filled cavity with a thin-film multilayer coating having reflection properties for at least one selected from the group consisting of infrared radiation and solar radiation, wherein the thin-film multilayer coating comprises a single metallic functional layer and two dielectric films, the single metallic functional layer being placed between the two dielectric films, wherein each of the dielectric films comprises an absorbent layer and two dielectric layers, each absorbent layer being placed between the two dielectric layers in the dielectric films, and wherein absorbent material of at least one of the absorbent layers is predominantly in the dielectric film subjacent to the metallic functional layer or predominantly in the dielectric film superjacent to the metallic functional layer in such a way that: either the absorbent material of the absorbent layer is predominantly in the dielectric film subjacent to the metallic functional layer, and the thin-film multilayer coating is positioned on the second face of the first substrate; or the absorbent material of the absorbent layer is predominantly in the dielectric film superjacent to the metallic functional layer, and the thin-film multilayer coating is positioned on the first face of the second substrate.
