Abstract
A material includes a transparent substrate coated with a stack of thin layers successively including, starting from the substrate, an alternation of three silver-based functional metallic layers and of four dielectric coatings, referred to, starting from the substrate, as M1, M2, M3 and M4, wherein the thickness of the first functional layer is less than the thickness of the second functional layer and less than the thickness of the third functional layer, the dielectric coatings M1 and M2 each have an optical thickness Eo1 and Eo2 satisfying the following equation: Eo2<1.1 Eo1.
