More Information
Summary:A transparent substrate is provided on a main face with a stack of thin layers including a single metallic functional layer having properties of reflection in the infrared region and/or in the solar radiation region, in particular based on silver or on silver-containing metal alloy, and two antireflective coatings. The antireflective coatings each include at least one dielectric layer. The functional layer is positioned between the two antireflective coatings. At least the antireflective coating located between the substrate and the functional layer, indeed even both antireflective coatings, include(s) a layer including silicon-zirconium nitride, SixZryNz, with an atomic ratio of Zr to the sum Si+Zr, y/(x+y), which is between 25.0% and 40.0%, these values being incorporated, indeed even between 27.0% and 37.0%, these values being incorporated.
