Low-emissivity coated glass ("Low-E" glass) is a film made of metal or metal compound coated with a low-emissivity function on the surface of the glass, so that the glass surface has a higher reflectance of infrared light with a wavelength of 4.5~25um. Glass, low-emissivity coated glass can also be combined with solar control functions to become solar control low-emissivity glass. The products are rich in color and have good visible light transmission effects and superior heat insulation performance. Low-E glass has the characteristics of low heat transfer coefficient and infrared reflection. Its main function is to reduce the radiation energy transfer of indoor and outdoor far infrared rays, and allow solar radiation to enter the room as much as possible, thereby maintaining the indoor temperature, saving heating, The cost of air-conditioning costs, visible light transmission is higher, the color of its reflected light is lighter, and it is mostly used in cold regions of middle and high latitudes. Properly control the transmission of Low-E glass, so that it can not only reflect part of the solar radiation, but also reduce the transmission of indoor and outdoor thermal radiation energy. This Low-E glass product has moderate visible light transmission, and the color of the reflected light is mostly The light blue color has a certain decorative effect. Therefore, this product has a stronger applicability and a wider range of options. It can be widely used in high, medium and low latitude areas, and it also prevents external heat from entering the room in summer. Function, suitable for hot areas in the south.
