Abstract
The invention relates to a transparent substrate, in particular made of glass, provided with a thin-film stack including at least one metallic layer with infrared reflection properties, in particular a low-emission. layer, arranged between two dielectric-based coatings, the underlying coating having a wetting layer based on zinc oxide ZnO, optionally doped with aluminium ZnO:Al, directly in contact with the metallic layer. According to the invention, each of the two coatings based on the dielectric material comprises at least one layer with high refractive index, greater than or equal to 2.2.
