Abstract
A subject matter of the invention is a glass-ceramic sheet provided, on at least a portion of at least one of its faces, with a coating of thin layers comprising at least one thin functional layer composed of a metal based on niobium metal Nb, or of an oxide based on a niobium oxide NbOx in which x is at most 0.5, the or each thin functional layer being framed by at least two thin layers made of dielectric materials, the physical thickness of the thin functional layer or, if appropriate, the combined physical thickness of all the thin functional layers being within a range extending from 8 to 15 nm.
