Изоляционные стекла (изолированное стекло, Low-E стекло)

Insulating glass can be sorted to double-layer andmulti-layer insulating glass. We can use different rawglass for different requests, such as ordinary flat glass,patterned glass, color glass or laminated glass togetherwith frames (metal frames or glass bar) to make insulatingglass by glued joint, jointing or welding.Properties of Insulating Glass:. Optical performance: insulating glass can have various optical performances according to raw glass used. The range of visible light transmittance is 10% 80%. Light reflectivity is 25% 80%. The total transmission is 25% 50%.. Heat-insulating property: insulating glass has perfect heat-insulating property. Under some conditions, its heat-insulating property can be better than concrete wall. According to statistics, in some European countries, using insulating glass can save 40 50 L fuel oil per per year than ordinary single glass.. Sound-insulating performance: insulating glass has perfect sound-insulating performance too. Its sound- insulating effects are different according to the kind and strength of the noise. Generally, noise can be reduced 30 44 dB, traffic noise can be reduced 3l 38 dB, that means the noise of streets and cars can be reduced to the quiet level required by school rooms.. Under some relative temperature, it will dewing when the surface temperature of glass under 5, thenfrost (under 0). That will severely influence the perspective and lighting of glass and cause some other bad effects. But the status can be better if insulating glass is used..
