According to the construction of energy-efficient housing design expert reports, on a window, the house heat loss through the window frame is mainly conduction, radiation glass, window and door frames pages gap convection way of insulating glass roof, which will have a "hollow glass "emerged. In fact, "insulating glass" is not "empty" hollow glass, hollow glass according to the technical requirements of the two spacing is generally 8mm, the test proved that if the spacing of 8mm full vacuum, atmospheric pressure, the glass will be crushed. Therefore qualified hollow glass. Its mezzanine space that is 8mm thick spacing must be filled with an inert gas of argon and krypton. After filling the hollow glass curtain, tests showed their K values ??(thermal limit) at year-vacuum state, also down 5% hollow glass strip, which means better insulation properties. Further, as an alternative member of the air from heavy gas then its insulating value is 1.4W / (m2.K). Thinning the thickness of the metal layer, the light transmittance can be increased to about 60% -60%. Infrared reflectivity of such an extremely thin coating has a very good protection too can the role, but also still very high value, 85% or 75% range. An intermediate layer of 12mm air filled with heavy gas, with a coating insulation values ??of up to 1.6-1.9W / (m2.K). Rizhao hollow glass, glass Yaohui preferred, hollow glass roof provided by Jinan Glass Co., Ltd. Yaohui. Rizhao hollow glass, glass Yaohui preferred, Yaohui hollow glass roof Jinan Glass Co., Ltd.
