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.
