Purpose of the development: Creation of solar-protective and energy-efficient coatings on glass.

Recommended application field: Different industries of national economy. Technology and facility elements contain a considerable volume of know-how.

Advantages over analogues: As compared with ordinary glass, glass with energy-efficient coatings features enhanced up to 80-90% reflective ability for long-wave infrared radiation. That enables, depending on the coating type (one layer or multi-layer) to bring down heat losses from rooms by 30-45% or solar heat penetration through window glass. Both coatings types belong to low-emission coatings class due to low value of emissivity. By the technical characteristics glass with energy-efficient coating compares well with foreign analogues, with capital and operational costs of its production much lower.

The development stage readiness: Pre-production model is made

Description of the development:
()
There has been developed a laboratory technology for application of solar-protective and energy-efficient optically transparent current-conductive 0.15-1.2 мm - thick glass coatings. The technology enables to produce both one-layer semiconductive and multi-layer (three-, five-layer with alternate metal and dielectric layers) coatings. The drop in visual transmittance does not exceed 10% for glass with energy-efficient coatings, and it can reach 10-50% for glass with solar-protective coatings, depending on requirements to light comfort. Semiconductive coatings belong to the "hard" type (resistant to abrasion, moisture effect; multi-layer ones fall into the group of "soft" coatings (relatively vulnerable to outside effects and can be used with a laminating film on the coating (solar-protective version). From the point of view of energy-efficiency use of "soft" coatings is more proficient. Fluorine-doped tin oxide or tin-doped indium oxide are used in production of low-emission coatings. Use of indium oxide provides bet-ter manufacturability because changes in the doping element (tin) con-centration enables to widely vary the material's properties.
