A substrate, or a transparent glass substrate, including a thin-film multilayer including an alternation of four functional metallic layers, or functional layers based on silver or on a metal alloy containing silver, and five antireflection coatings, each antireflection coating including at least one antireflection layer, so that each functional metallic layer is positioned between two antireflection coatings. The thickness of the second, third, and fourth functional metallic layers starting from the substrate is substantially identical, with a ratio of the thickness of one layer to the thickness of the preceding layer between 0.9 and 1.1 inclusive of these values, and the thickness of the first functional metallic layer is about half the thickness of the second functional metallic layer, with a ratio of the thickness of the second metallic layer to the thickness of the first functional metallic layer between 1.9 and 2.2 inclusive of these values. |
