Abstract
A low emissivity glazing on a pane of glass, includes a set of thin layers formed by vacuum deposition assisted by magnetron, the set of thin layers including at least one metal layer reflecting infra-red rays between one or more dielectric layers located between the metal layer and the glass sheet, the metal layer being provided with a protective barrier coating, including a layer of titanium oxide or sub-oxide, deposited in a weakly oxidizing atmosphere at reduced pressure via a conducting titanium oxide cathode.
