The invention relates to low-emissivity and anti-solar glazing systems that change only very little in properties when they are subjected to a heat treatment. They comprise a stack of thin layers comprising an alternating arrangement of n infrared radiation reflecting functional layers and n+1 dielectric coatings, characterized in that: (i) the first dielectric coating comprises a layer made from an oxide in contact with the substrate, (ii) the portion of the coating stack between two functional layers comprises, in order: a barrier layer, a zinc oxide-based layer, a layer of zinc-tin mixed oxide, a nucleation layer, and (iii) the last dielectric coating comprises a layer made from an oxide other than silicon oxide with a thickness greater than 3 nm overlaid with a layer made from a silicon nitride or a silicon oxide with a thickness greater than 10 nm superposed thereon.

Low-emissivity and anti-solar glazing

The invention relates to a method for manufacturing a coated object () through deposition of at least one transparent, conductive metal-oxide layer () on a substrate (), comprising the deposition (I) and preferably subsequent temperature treatment (II) of the coating (). After the optional temperature treatment (II), the surface texture () of the coating () is statistically adjusted through an etching process.
