WINDOW UNIT FROM THE INSULATING GLASS, INCLUDING DOUBLE SILVER COATING HAVING INCREASED RATIO OF THE SOLAR RADIATION HEAT TRANSFER COEFFICIENT TO THE TOTAL HEAT TRANSFER COEFFICIENT, AS WELL AS CORRESPONDING COATED ARTICLE FOR USE IN THE WINDOW UNIT FROM INSULATING GLASS OR ANOTHER WINDOW Russian patent published in 2018 - IPC C03C17/36 

FIELD: glass.

SUBSTANCE: invention relates to the made of insulating glass window unit. Applying the low-emissivity coating onto the window unit glass substrate, which comprises, in order of distance from the substrate, the following layers: containing silicon nitride dielectric layer; containing titanium oxide dielectric layer; containing zinc oxide first lower contact layer; containing silver first infrared radiation reflecting layer, first upper contact layer; containing zinc stannate layer; containing zinc oxide second lower contact layer; containing silver second infrared radiation reflecting layer; second upper contact layer; dielectric layer.

EFFECT: technical result is increase in the ratio of the solar radiation heat transfer coefficient to the total heat transfer coefficient.
