Low-E glass, also known as low-e glass, is a film product composed of multiple layers of metal or other compounds coated on the surface of the glass. The coating layer has the characteristics of high transmission of visible light and high reflection of mid- and far-infrared rays, which makes it have excellent heat insulation effect and good light transmittance compared with ordinary glass and traditional architectural coated glass. Low-e insulating glass is a new type of building material that has good heat insulation, sound insulation, beauty and application, and can reduce the weight of the building. It is made of two (or three) glass, using a high-strength and high-air-tight composite adhesive to bond the glass sheet to an aluminum alloy frame containing a desiccant to make high-efficiency sound-insulating and heat-insulating glass.
