GREEN COLOURED HEAT TREATABLE COATED ARTICLE HAVING LOW SOLAR FACTOR VALUE Russian patent published in 2018 - IPC C03C17/36 

FIELD: glass.

SUBSTANCE: invention relates to coated glass, having a green colour. Coated article includes glass, on which layers are applied in the following sequence as distance from the glass increases: first dielectric layer, containing silicon nitride; first infrared-reflecting layer, containing NbZr; second dielectric layer containing silicon nitride; second IR-reflective layer containing NbZr; third dielectric layer, containing silicon nitride. Coated article has glass side/exterior reflective green coloration comprising a glass side/exterior a* value of from -4.0 to -16.0 and a glass side/exterior b* value of from +7.0 to -15.0. If measured monolithically glass article has a solar factor (SF) value of no greater than 0.40 and a solar heat gain coefficient (SHGC) value of no greater than 0.42 and/or if an insulating glass window unit having two glass substrates has an SF value of no greater than 0.25 and an SHGC value of no greater than 0.27.

EFFECT: technical result is to provide an article with green coloration with a low solar factor and/or a solar heat gain coefficient.
