A material includes a transparent substrate coated with a stack of thin layers including at least one silver-based functional layer, wherein the stack includes a protective coating deposited on top of at least one portion of the functional layer, the protective coating including: a lower protective layer having a thickness of between 1 and 10 nm, a central protective layer based on carbon graphite located on top of the lower protective layer, and an upper protective layer having a thickness of between 1 and 10 nm located on top of the central protective layer.

Glazing comprising a protective coating

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, referred to, starting from the substrate, as M1, M2, M3 and M4, wherein the thickness of the first functional layer is less than the thickness of the second functional layer and less than the thickness of the third functional layer, the dielectric coatings M1 and M2 each have an optical thickness Eo1 and Eo2 satisfying the following equation: Eo2&#x3c;1.1 Eo1.

Substrate provided with a stack having thermal properties

A transparent substrate includes a stack of thin layers successively including, starting from the substrate, an alternation of three metallic functional layers, in particular of functional layers based on silver or on silver-comprising metal alloy, and of four antireflective coatings, each antireflective coating including at least one dielectric layer, so that each metallic functional layer is positioned between two antireflective coatings, wherein: the thicknesses of the metallic functional layers, starting from the substrate, increase as a function of the distance from the substrate, the second metallic functional layer is directly in contact with a blocking layer, referred to as second blocking layer, chosen from a blocking underlayer and a blocking overlayer, respectively referred to as second blocking underlayer and second blocking overlayer, the second blocking underlayer and/or the second blocking overlayer exhibits a thickness of greater than 1 nm.
