Low emissivity coated glass (also known as Low-E glass) is a layer of metal or metal oxide film deposited on the float glass, one or two layers of Ag - based special coating. Low emissivity glass Low-E glass, a coated glass with high reflection ratio to the far infrared wavelength of 4.5um-25um, can effectively reduce the absorption of solar energy or control the loss of energy and reduce the heat transfer coefficient of glass.
