Low-e Glass is short for LOW Emissivity Glass. It is produced by hollow glass equipment or insulating glass production line. Greatly reduce glass heat radiation by coating in the glass surface to achieve the goal of energy saving. Now a lot of high-rise residential buildings, office buildings, etc use this kind of glass. Today we talk about what benefit will low-e energy saving glass bring to People's Daily life. First we need to know these glass. Due to differences in technology, different low-e glass http://www.constructionGlassbiz.com/product/low-emissivity-glass-e-low-Manufacturers-Suppliers.html have different energy saving effects. As the domestic market share more than 90% of low-e, it has gone through a journey of three generations. Single silver low-e is the first generation of energy-saving glass, glass surface emissivity value E = 0.1 ~ 0.15, the heat transfer temperature difference between the K value is about 1.8 ~ 2.0 W/M2. However, as the increase of the glass transmittance, glass heat insulation ability also increased a lot. A leading domestic energy-saving glass through technology , solved this problem in 2005, make a progress in technology, and gradually develop second generation energy saving -- - double silver low-e glass and the third generation of energy saving - three silver low-e glass. Double silver low-e emissivity can be reduced to 0.05 or so, three silver low-e arrived at the limit point of 0.02. The difference in temperature heat transferrence is better than single silver which has fallen by 12% to 15%. Three silver and double silver low-e belong to high efficiency and energy saving glass, and three silver low-e products energy-saving glass is the best in the world. The reason why three silver and double silver low-e glass save energy is that through nano coating deposition techniques, using multiple reflection interference principle of heat energy, put in the 380 ~ 760 nm wavelength of visible light, and will carry heat up to 760 ~ 2500 nm infrared light reflected out. Thus the maximum thermal light filtering into cold light source. Ordinary white insulating glass, infrared heat is 530 watts. High single silver low-e insulating glass, infrared heat is about 220 watts. South bo efficient double silver low-e insulating glass, infrared heat is 50 watts. South bo efficient three silver low-e insulating glass, infrared heat gain is about 40 watts. From a single silver low-e to three silver low-e makes us feel hot infrared thermal radiation heat from 2 bath bully lamp heat down to a 40-watt incandescent lamp. Similarly, in effective low-e energy saving glass room, due to the greatly reduced unit heat , people in the room feel more comfortable . High efficiency and energy saving of three silver and double silver low-e glass create a warm and harmonious living environment for you. what's mare, because of the double silver low-e and three silver low-e are more excellent than single silver low-e in energy saving performance. The west has been use of them in large area, and three silver low-e even walk into the ordinary homes in the United States.
