FIELD: power industry.
SUBSTANCE: group of inventions relates to coated products that include two or more functional infrared (hereinafter – IR) radiation-reflecting layers that can be embedded at least between dielectric layers and/or their manufacture method. The coated product includes coating supported by glass substrate. Coating contains the first dielectric layer containing silicon nitride on glass substrate, the first infrared (IR) radiation-reflecting layer containing indium-tin oxide (hereinafter – ITO) on glass substrate, the second dielectric layer containing silicon nitride on top of at least the first IR-reflecting layer, the second IR-reflecting layer containing zirconium nitride, the third dielectric layer containing silicon nitride. The first dielectric layer is located between at least glass substrate and the first IR-reflecting layer containing ITO. The second IR-reflecting layer is located on top of at least the first and the second dielectric layers containing silicon nitride, so that the second dielectric layer containing silicon nitride is located between at least the first IR-reflecting layer containing ITO and the second IR-reflecting layer containing zirconium nitride. The third dielectric layer is located on glass substrate on top of at least the second IR-reflecting layer containing zirconium nitride. The first IR-reflecting layer containing ITO has a thickness of 300-800 Å, and the second IR-reflecting layer containing zirconium nitride has a thickness of 130-300 Å. Coating has a normal radiation coefficient (En) of no more than 0.30. The coated product has: a coefficient of visible light transmittance from about 15 to 80%, a coefficient of visible light reflection from the film side of no more than 15%, a solar heat gain coefficient (SHGC) of no more than 0.45, a* value when reflected from the glass side from -14.0 to +1.6 and a ratio of light transmittance to light-to-solar gain (LSG) of at least 1.10.
EFFECT: increase in the efficiency of solar radiation control.
