The invention relates to a transparent glass substrate including at least one glass sheet provided with a thin-film multilayer coating acting on solar radiation, having a light transmission of greater than 10% and an emissivity of less than 50% after a heat treatment, such as a bending or toughening treatment, characterized in that said multilayer coating includes: a niobium Nb functional layer with a thickness of between about 5 nm and about 35 nm; and at least one layer of another material, chosen from the group formed by Ti, Mo, B, Al or an alloy comprising at least one of these elements, which is placed relative to the glass substrate above the functional layer, said layer having a thickness of between about 1 nm and about 5 nm. The invention also relates to monolithic glazing or double glazing incorporating such a substrate.

Solar-protection glazing having an improved light transmission coefficient

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

A glazing for thermal control and heating is provided. The glazing includes a transparent substrate including glass and provided with a thin-film stack including a plurality of functional layers. The thin-film stack includes at least three silver-based functional layers. The thin-film stack has a resistance R&#x3c;1.5&#x3a9; per square.

Transparent substrate which can be used alternatively or cumulatively, for thermal control, for electromagnetic armour and for heated glazing

A transparent substrate having a glazing function, provided with a thin-film multi-layer coating, which acts on solar radiation, applicable, for example, in the architectural or automotive fields. The multilayer coating comprises at least two absorbent functional layers each flanked by two transparent layers comprising a dielectric material. Preferably, the functional layers are based on a metal belonging to the group consisting of: niobium, tantalum, molybdenum and zirconium, and the metal or at least one of the functional layers may be partially or entirely nitrided.

Glazing provided with a stack of thin layers

A transparent substrate comprises glass and is provided with a thin-film stack including a plurality of functional layers. The thin-film stack comprises at least three silver-based functional layers. The thin-film stack has a resistance R&#x3c;1.5 &#x3a9; per square. The transparent substrate may undergo at least one transformation operation involving a heat treatment at a temperature of at least 500&#xb0; C., so as to make it possible to achieve, using the substrate, alternatively or cumulatively, thermal control and/or electromagnetic shielding and/or heating.

Transparent substrate which can be used alternatively or cumulatively for thermal control, electromagnetic armour and heated glazing

The subject of the invention is a transparent substrate, especially a glass substrate, provided with a thin-film multilayer acting on solar radiation, the multilayer being deposited by magnetron sputtering, characterized in that it includes at least a lubricating film of high optical index n, this lubricating film being associated with at least one sublayer, which is based on silicon nitride or oxynitride or carbonitride, or based on aluminum and/or zirconium nitride or oxynitride or carbonitride, or a mixture of at least two of these compounds (mixed Si&#x2014;Al or Si&#x2014;Zr nitrides or oxynitrides or carbonitrides).
