Low-emissivity glazing

Abstract

The present invention relates to a glazing coated with an assembly of thin layers using vacuum deposition, said glazing having reflective properties for infrared radiation, while retaining a high transmission in the visible range, and retaining its properties when subjected to a thermal treatment such as bending/toughening. The glazing comprises one or more silver-based layers and dielectric layers, of which at least one underlying dielectric layer in relation to at least one silver-based layer is a titanium oxide- or oxynitride-based layer such as TiMOx or TiMOxNy, in which M is a metal or a plurality of metals or silicon, wherein these metals or silicon are contained in sufficient atomic proportions to prevent a significant transformation of the crystallographic structure of the previously deposited titanium oxide-based layer under the action of the thermal treatment.
