    • The invention relates to a glass substrate (10) having, on a main side, a stack of thin layers comprising a functional metallic layer (40) with reflective properties in infrared and/or solar radiation, particularly silver-based or based on a metallic alloy containing silver, and two anti-reflective coatings (20, 60), said coatings each comprising at least one dielectric layer (22, 64) silicon-nitride based, possibly doped with at least one other element, such as aluminum, said functional layer (40) being placed between the two antireflective coatings (20, 60), characterized in that the optical thickness e60 in nm of the underlying antireflective coating (60) is: e60 = 5 x e40 + a, where e40 is the geometric thickness in nm of the functional layer (40) such as 13 4040
    • 本发明涉及一种玻璃衬底(10),该玻璃衬底(10)在主侧具有包括功能金属层(40)的薄层叠层,所述功能金属层在红外和/或太阳辐射下具有反射特性,特别是银基或基于金属 含有银的合金和两个抗反射涂层(20,60),所述涂层各自包括至少一个基于氮化硅的介电层(22,64),其可能掺杂有至少一种其他元素(例如铝),所述功能 (40)放置在两个抗反射涂层(20,60)之间,其特征在于下面的抗反射涂层(60)的光学厚度e60(nm)为:e60 = 5×e40 + a,其中e40是几何厚度 以功能层(40)的nm为单位,例如134040 <18,并且其中a是数值= 25±15。
