Low –E Glass
Low-E glass is a kind of high performance, low-emissivity products. The vacuum sputtering process coats glass surfaces with several layers of different materials. Among these, a silver layer effectively reflects infrared rays while maintaining excellent thermal performance. Beneath the silver layer is an anti-reflective tin oxide(SnO2)base layer that increases the transparency of the glass, the silver layer is an isolating nickel-chromium(NiCr)alloy coating. The main function of the top anti-reflective tin oxide(SnO2)layer is to protect the other coating layers. This product offers the high transparency, low reflectivity, and good thermal insulating and energy-savings properties required of modern architectural glass and green building design.
