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, so that each functional metallic layer is positioned between two dielectric coatings. The thicknesses of the three functional layers and the thicknesses of the dielectric coatings are selected in order to give the materials solar factor values of less than 20% for a light transmission of the order of 40%.
