The invention relates to a transparent substrate with a glass function having a stack of thin layers controlling solar radiation. According to the invention, the stack comprises at least two functional absorbing layers, each one flanked by two transparent layers containing a dielectric material. The functional layers are preferably made of a metal belonging to the niobium, tantalum, molybdenite, or zirconium group, and the metal of at least one of the functional layers may partially or completely be nitride. The invention particularly applies to the building and automobile fields.
L'invention concerne un substrat transparent fonction verrire muni dun empilement de couches minces agissant sur le rayonnement solaire. Selon linvention, lempilement comporte au moins deux couches fonctionnelles absorbantes encadres chacune par deux couches 15 transparentes comprenant un matriau dilectrique. Les couches fonctionnelles sont de prfrence base dun mtal appartenant au groupe du niobium, du tantale, du molybdneet du zirconium et le mtal dau moins lune des couches fonctionnelles peut tre partiellement ou entirement nitrur.20 Linvention sappliquenotamment dans les domaines du btiment et de lautomobile. 25
