Note: hollow intermediate glass enclosed dry air, Heze insulating glass, therefore, according to changes in temperature, barometric pressure, the internal air pressure also changes, but produces only a small glass surface deformation. In addition, could generate a tiny warping manufacturing, 5mm hollow glass, construction process may also form distortion. It includes such factors into account, sometimes reflecting some changes accordingly, should be paid. The different selection of colors, reflecting not the same. ? Empty glass is sealed, the hollow glass in the best insulation. Gold, copper and silver metal coating far infrared region, the wavelength range is greater than 4μm, the high reflectivity. The metal coating is a typical thickness of all the reflectance of 90% -95%, the equivalent of high infrared reflectivity low emissivity (Low-e), which will reduce the insulating glass units inside and outside the glass radiation conversion, and this Correspondingly, compared with a standard 12mm air layer hollow glass member from its insulation value can 0.3W / (m2.K). 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, hollow glass, 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). Substrate insulating glass is generally divided into colorless float glass, coating or LOWE coated glass, tempered glass, laminated glass, glazed glass. Thickness of 3-12mm. The topsheet should always pay attention to the surface quality of the glass, without scratches, abrasions, chipping, bubbles obvious defects, such as slag, but also pay attention to whether there is a glass coating and LOWE oxidation. To bring gloves masks and other protective equipment when working LOWE insulating glass, are not allowed to touch the membrane surface. _ Yaohui hollow glass roof quality assurance (certification) _ Heze hollow glass provided by Jinan Glass Co., Ltd. Yaohui. Jinan Yaohui Glass Co., Ltd. (www.jyhhc.com/) is a professional, "insulating glass, tempered glass, laminated glass, LOW-E glass" of the company.
