    • 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, and a barrier layer directly superposed on the last functional layer furthest away from the substrate, characterized in that: (i) the first dielectric coating closest to the substrate comprises a layer made from an oxide, in direct contact with the substrate, (ii) the internal dielectric coating or coatings surrounded by two functional layers comprise a layer made from a silicon nitride or a silicon oxide with a thickness greater than 5 nm surrounded on both sides by layers made from an oxide other than silicon oxide with thicknesses greater than 5 nm, (iii) the barrier layer is based on zinc oxide or consists of an indium oxide possibly doped with tin, and (iv) the last dielectric coating furthest away from the substrate comprises, in order starting from the substrate: a layer made from an oxide other than silicon oxide with a thickness greater than 3 nm and a layer made from a silicon nitride or a silicon oxide with a thickness greater than 10 nm.
    • 本发明涉及低发射率和抗太阳能玻璃窗系统,它们在进行热处理时其特性变化很小。 它们包括一叠薄层,其包括反射功能层和n + 1电介质涂层的n个红外辐射的交替布置,以及直接叠加在最远离衬底的最后功能层上的阻挡层,其特征在于:(i) 最接近衬底的第一电介质涂层包括由与衬底直接接触的氧化物制成的层,(ii)由两个功能层包围的内部电介质涂层或涂层包括由氮化硅或氧化硅制成的层, 厚度大于5nm的两面由厚度大于5nm的氧化硅以外的氧化物制成的层,(iii)阻挡层基于氧化锌或由可能掺杂锡的氧化铟组成, iv)最远离衬底的最后的电介质涂层包括从衬底开始的顺序:由氧化硅以外的氧化物制成的层, cnness大于3nm的层和由氮化硅或厚度大于10nm的氧化硅制成的层。
