LOW-E glass is a kind of processed glass products coated with a spectrally functional film made by sputtering to achieve transparent light-transmissive. These films are selective with high reflection to infrared light and no reflection on visible light. Low-E films are made by physical vapor deposition, and the sputtering target is the source material. Under normal circumstances, the energy-saving performance of the ordinary uncoated three-glass two-chamber insulating glass is not as good as that of the single-chamber insulating glass using Low-E coated glass. LOW-E glass can be divided into online and offline Low-E coated glass according to the processing method. Therefore, Low-E coated glass plays a vital role in residential glass door and window applications. 1. What is Low-E glass?
