Glazing provided with a stack of thin layers acting on solar radiation
First Claim
1. A transparent substrate, provided with a stack of thin layers acting on solar radiation, characterized in that said stack includes at least one functional layer of essentially metallic nature and predominantly comprising at least one of the metals belonging to the group consisting of niobium, tantalum and zirconium, said functional layer being surmounted by at least one overlayer based on aluminum nitride, aluminum oxynitride, silicon nitride or silicon oxynitride, or on a mixture of at least two of these compounds.
