Study on Optical and Thermal Properties of Low-E Glass

A coating methods and the structure of Low-E glass are described in this paper, and the optical and thermal properties of the samples are analyzed as well. The results show that the Low-E glass has a high transmittance in visible region and with a higher reflectance in middle-infrared band and far-infrared band. It can effectively prevent the heat through the glass. Therefore, Low-E glass can save energy by letting enough sunlight into the room and by impeding the heat through the glass effectively.
