Coated glass (heat reflective glass) is coated by horizontal magnetically controlled high rate sputtering. It can effectively control the transmission of visible light and low infrared. Coated glass has the higher reflecting power against the sunlight with the reflection ratio up to 20%~40%, so it can save the energy consumption of the indoor air-conditioners and at the same time it has good shading property, so it makes the indoor light a little softer and more pleasant. Low-E glass is also called the Low-emittance (Low-E) coated glass and is made by the method of vacuum magnetron sputtering by evenly plating the glass surface with metal or metallic oxide layers, thus forming the low-emittance coating and producing the coated glass.
