Abstract
A solar protection and/or thermal insulation glazing including a substrate, in particular a glass substrate, provided with a stack of thin layers which act on solar radiation, the stack having the succession of the following layers, starting from the surface of the glass: an underlayer or a set of underlayers, the underlayer(s) having dielectric materials, a layer based on titanium oxide also having silicon, the overall Si/Ti atomic ratio in said layer being between 0.01 and 0.25, and in which Si and Ti represent at least 90% of the atoms other than oxygen, the thickness of the layer being between 20 and 70 nm, an overlayer or a set of overlayers, said overlayer(s) having dielectric materials.
