Zusammenfassung:	Method of manufacturing glazed pieces provided with a multi-layer coating on glass substrate comprises: depositing a first transparent dielectric layer, followed by an infra-red radiation reflecting functional layer; depositing first and second protective layers having specified electronegativity differences to oxygen; and depositing at least one second transparent dielectric layer. The fabrication of a glazed piece provided with a multi-layer coating deposited by cathodic atomization under reduced pressure on a glass substrate consists of: (a) depositing a first transparent dielectric layer, followed by a functional layer based on a material which reflects infra-red radiation; (b) depositing a first protective layer with at most 3 nm of a material having an electronegativity difference to oxygen of less than 1.9, followed by the deposition of a second protective layer with at most 7 nm of a material with an electronegativity difference to oxygen of greater than 1.4; and (c) depositing at least one second transparent dielectric layer. An Independent claim is also included for a glazed piece provided with a multi-layer coating fabricated by this method.
