Abstract
A material includes a transparent substrate coated with a stack of thin layers I including a lower coating including at least one absorbent layer, a single silver-based functional metal layer and an upper coating including at least one dielectric layer. The absorbent layer is separated from the substrate and from the functional layer by one or more dielectric layers. The material, once fitted in a double glazing, makes it possible to obtain a high selectivity, in particular of greater than 1.45, an interior and exterior light reflection of less than 25% and bluish hues in exterior reflection and in interior reflection.
