[China Glass Net] The energy consumption of building doors and windows is similarly compared to the fact that the energy consumption of each non-energy-saving window is equivalent to the energy consumption of a dozen watts of long-light lamps over the years. In this era of increasing energy conservation and consumption reduction, since the heat loss of the exterior door and window glass is the main part of the building energy consumption, the use of new glass that can effectively save energy and reduce consumption can greatly reduce the consumption of heating and cooling. Fuel, thereby reducing carbon emissions. Coated Glass Low-E glass, also known as low-emission coated glass, is a series of films made of multiple layers of metal or other compounds coated on the surface of the glass. The coating layer has high transmission of visible light and high reflection of mid-range infrared rays, and has excellent heat insulation effect and good light transmittance compared with ordinary glass and conventional architectural coated glass. Ordinary float glass has an emissivity of up to 0.84. When a low-emissivity film based on silver is applied, the emissivity can be reduced to less than 0.15. The use of Low-E glass to fabricate doors and windows of buildings can greatly reduce the transfer of indoor thermal energy to the outside, achieving an ideal energy saving effect. Low-E glass has a high transmittance to visible light in sunlight, up to 80%, and the reflectance is very low, which makes the optical performance greatly improved compared with the traditional coated glass. A softer, more comfortable light environment. Vacuum glass Vacuum glass is a new type of product. It is separated by appropriately distributed micro-pillars. The gap layer is only 0.1~0.2 mm. The cavity is vacuum-free and has a vacuum of more than 0.1 Pa. As a new generation of energy-saving glass, it has better heat insulation and heat preservation performance, and its thermal insulation performance is about 4 times that of a single piece of ordinary glass. Because of the high thermal resistance of vacuum glass, it has better anti-condensation and frosting properties. It is extremely beneficial to winter lighting in severe cold areas. Smart glass In order to solve the different requirements of glass insulation performance in different climate regions and different seasons, the United States began to study smart glass. This kind of intelligent glass working with electrochromic principle has been officially put into production after long-term experimental research, which makes glass enter. The era of intelligence.
