Abstract: The invention relates to 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 (140) and two dielectric films (120, 160), said films each comprising at least one dielectric layer (122, 126; 162, 166), said functional layer (140) being placed between the two dielectric films (120, 160), characterized in that at least one dielectric film (120, 160), or both dielectric films (120, 160), includes an absorbent layer (123, 165) which is placed in the dielectric film between two dielectric layers (122, 126; 162, 166), the absorbent material of the absorbent layer(s) (123, 165) being predominantly in the dielectric film (120) subjacent to the metallic functional layer (140) or predominantly in the dielectric film (160) superjacent to the metallic functional layer (140).

Abstract: A multiple glazing unit with at least three substrates which are held together by a frame structure, in which at least two intermediate gas-filled cavities lie each between two substrates, at least one substrate has, on at least one face in contact with an intermediate gas-filled cavity, an antireflection film which is in a face-to-face relationship relative to said intermediate gas-filled cavity, with an insulating film having reflection properties for infrared and/or in solar radiation.

Abstract: Transparent especially glass, substrate (6) having at least on one of its sides an antireflection coating made from a stack (A) of thin dielectric layers of alternating high and low refractive indices, characterized in that the stack comprises, in succession: a high-index first film (1) having a refractive index n1 between 1.8 and 2.3 and a geometrical thickness e1 of between 10 and 25 nm; a low-index second film (2) with a refractive index n2 of between 1.40 and 1.55 and a geometrical thickness e2 of between 20 and 50 nm; a high-index third film (3) with a refractive index n3 of between 1.8 and 2.3 and a geometrical thickness n3 of between 110 and 150 nm; and a low-index fourth film (4) with a refractive index n4 of between 1.40 and 1.55 and a geometrical thickness e4 of between 60 and 95 nm, the algebraic sum of the geometrical thickness e3+e1 being between 125 and 160 nm.
