Abstract: The invention relates to a glazing assembly comprising at least one transparent substrate, especially made of glass, provided with a thin-film multilayer comprising, in the following order starting from the substrate, at least: (a) a first dielectric layer comprising a barrier layer acting as a barrier to the diffusion of oxygen and chosen from silicon nitrides; (b) a lower stabilizing layer made of a metal or metal alloy X; (c) a functional layer having reflection properties in the infrared and/or in the solar radiation, especially a metal layer; (d) an upper metal blocking layer made of a metal or metal alloy Y; (e) a second dielectric layer comprising a barrier layer acting as a barrier to the diffusion of oxygen and chosen from silicon nitrides; and (f) optionally, a protective oxide layer; in which multilayer the metal or alloy X of the lower stabilizing layer is different from the metal or alloy Y of the upper blocking layer.

Abstract: The invention relates to a transparent substrate, especially of the glass type, which comprises a coating that contains at least one layer C based on silicon or aluminum [nitride, carbonitride, oxynitride or oxycarbonitride] or on a mixture of the two, which is surmounted by a cover layer, characterized in that the cover layer is an oxide-base mechanical protection layer, this oxide being optionally oxygen-substoichiometric or oxygen-superstoichiometric and/or optionally nitrided. Application to the production of a glazing assembly, especially a multiple or laminated glazing assembly.
