INSULATING GLAZING WITH LOW-EMISSION AND ANTI-REFLECTION COATINGS Russian patent published in 2017 - IPC C03C17/36 E06B3/66 

FIELD: construction.

SUBSTANCE: glazing contains the first, second and third parallel spaced apart glass substrates. The first substrate faces the outer space, and the third - the inner space. The first and second low-emission coatings are applied to the inner surfaces of the first and third substrates. Each low-emission coating is thermally treated and their respective substrates have ΔE* values less than 2.5. On the opposite surfaces of the second substrate, the first and second anti-reflection coatings are disposed. Each low-emissivity coating comprises, in order of increasing distance from the substrate, of the following layers: a layer containing titanium oxide, a layer containing zinc oxide, an infrared radiation reflecting layer, containing silver, a layer containing metal, oxide or suboxide of Ni and/or Cr, a layer containing tin oxide, and a layer containing silicon nitride.

EFFECT: increase in visible light transmission, decrease in heat transfer coefficient and increase in the amount of solar heat input.
