    摘要: A transparent substrate particularly of glass, provided with a stack of thin layers having at least one metallic layer (4) having properties in the infrared range particularly having low emissivity and two coatings having a base of dielectric material located one (8) under and the other (9) over the layer having properties in the infrared range, as well as a protective metallic layer (5) place immediately over an in contact with the layer having properties in the infrared range, characterized in that in order to prevent the modification of properties of the stack, particularly optical and thermal properties, in the case where the substrate is submitted to a thermal treatment of the tempering or bending kind, firstly the second coating (9) having a base of dielectric material, includes a barrier layer for the diffusion of oxygen chosen from the following materials: components of silicon SiO2, SiOxCy, SiONNy, nitrates such as Si3N4 or AlN, carbides such as SiC, TiC, CrC, TaC of a thickness of at least 10 nanometers and preferably of at least 20 nanometers, and secondly the layer having properties in the infrared range is directly in contact with the underlying dielectric coating.
