The invention relates to a substrate (), especially a transparent glass substrate, provided with a thin-film multilayer comprising a functional layer () having reflection properties in the infrared and/or in solar radiation, especially a metallic functional layer based on silver or on a metal alloy containing silver, and two coatings (), said coatings being composed of a plurality of dielectric layers (), so that the functional layer () is placed between the two coatings (), the functional layer () being deposited on a wetting layer () itself deposited directly onto a subjacent coating (), characterized in that the subjacent coating () comprises at least one dielectric layer () based on nitride, especially on silicon nitride and/or aluminum nitride, and at least one noncrystalline smoothing layer () made from a mixed oxide, said smoothing layer () being in contact with said superjacent wetting layer ().

Substrate comprising a stack having thermal properties

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.

Substrate provided with a multilayer coating having thermal properties and an absorbent layer

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.

Substrate provided with a multilayer coating having thermal properties and absorbent layers

The invention relates to a substrate () provided with a thin-film multilayer comprising an alternation of n functional layers () having reflection properties in the infrared and/or in solar radiation, and (n+1) coatings (), where n&#x2267;1, said coatings being composed of a layer or a plurality of layers (), characterized in that, in order to preserve the optical and/or mechanical quality of the multilayer in the case in which the substrate () provided with said multilayer is subjected to a heat treatment of the toughening, bending or annealing type, at least one of the functional layers () includes a blocker coating () consisting of:
