The invention relates to a glass substrate including a stack of coating layers having control properties, in which stack comprises at least one niobium metal layer located between a layer of a dielectric material selected from SiNor TiOx and a layer of a protective metal material selected from TIN or Ni—Cr, conferring solar control and heat resistance properties on the glass substrate.

Coating with solar control properties for a glass substrate

The present invention provides a glass sheet having soda-lime-silica glass composition with a high visible light transmittance (L) of at least 89% with a dominant wavelength (DW) from about 490 to 505 nanometers and purity (Pe) of no more than 1% for control thickness of 5.66 mm and methods of making the same. The glass composition comprising a low iron raw material, a total iron oxide (FeO) of 0.02 to 0.06 wt. %, ferrous (FeO) from 0.006 to 0.02 wt. %, redox (FeO/FeO) from about 0.30 to 0.55, CrOfrom about 0.3 to 10 ppm, TiOfrom about 50 to 500 ppm, SnOfrom about 10 to 500 ppm, and a critical amount from about 0.10 to 0.25 wt. % of SO. The low content of iron oxide is achieved by the partial substitution of regular raw materials by low iron raw materials, with a complete substitution of regular dolomite by a low iron dolomite with a maximum content of 0.020 wt. % FeO.
