Abstract
Vehicle or building glazing having a solar control property includes a glass substrate supporting a stack of layers, including successively from the surface of the substrate, a first module M1 of layer(s) based on a dielectric material with a total thickness t1, a first layer TN1 including titanium nitride with a thickness of 5 to 35 nanometers, a first module M2 of layer(s) based on a dielectric material with a total thickness t2, a second layer TN2 including titanium nitride with a thickness of 5 to 35 nanometers, a third module M3 of layer(s) based on a dielectric material with a thickness t3. The cumulative sum of the thicknesses of the TN1 and TN2 layers including titanium nitride is greater than 30 nm, t1 being less than 30 nanometers, t2 being between 10 and 100 nm and t3 being greater than 10 nanometers. The ratio t1/t3 is less than 0.6.
