Low-E glass (Low Emissivity glass) is on the surface of glass plated with multi-layer metal or other compounds composed of film products. The coating layer has the advantages of high visible light transmittance and high reflection to the medium and far infrared rays, and has excellent thermal insulation effect and good light transmittance compared with the common glass and the traditional architectural coating glass.
