Abstract
The subject of the invention is a transparent substrate (1), in particular one made of glass, coated with a stack (7) of thin layers comprising at least one layer (4) having reflection properties in the infrared and/or in the solar radiation range, this layer (4) being interposed between a first and a second coating (3, 6) comprising a dielectric material. An interlayer (2) made of a material having a refractive index less than that of the substrate (1) is interposed between the substrate (1) and the stack (7) such that the difference in refractive indices between the substrate (1) and the layer (2) is at least 0.07 and preferably at least 0.12.
