GLASS WITH LOW-EMISSION COATING, RESISTANT TO HEAT TREATMENT Russian patent published in 2019 - IPC C03C17/36 C03C3/00 

FIELD: glass.

SUBSTANCE: double silver-plated glass (10) with low-emission coating (20), resistant to thermal treatment, providing effective sun-protection action at low solar factor, which transmits daylight inwards and minimizes loss of thermal energy, characterized by that said low-emission coating (20) contains SixNy/TiOx/ZnAlOx, respectively, as first three layers located outside the surface of glass (10), and the ratio of the thickness of the first layer Ag to the thickness of the second layer Ag is in range of 0.6–1.5, and said low-emission coating (20) after the first three layers, respectively, contains the following layers: first layer (24), reflecting infrared radiation, located on ZnAlOx layer; first barrier layer (25) containing NiCrOx, located on first layer (24) reflecting infrared radiation; average dielectric structure (26) containing ZnSnOx located on first barrier layer (25); second inner layer (27) containing ZnAlOx located on middle dielectric structure (26); second layer (28) reflecting infrared radiation located on second inner layer (27); second barrier layer (29) containing NiCrOx located on second layer (28) reflecting infrared radiation; third dielectric layer (30) containing ZnSnOx located on the second barrier layer (29); upper dielectric structure (31) containing SiOxNy located on third dielectric layer (30). Invention is developed in dependent claims.

EFFECT: present invention relates to double silver-plated glass with low-emission coating, which is resistant to thermal processes, which provides an effective degree of sun protection at low solar factor, as well as passing daylight to the middle and minimizing loss of heat energy.
