lt is one of coated glass that has higher reflection to the sunlight. wavelength from 2.5um to 25um and is also called Low-E coated glass. And it is divided into two series of colorless transparence and colored Low-E coated glass. Used in middle and high latitudes, colorless transparence glass' transmittance is higher than 70%. It can stop heat energy indoor from scattering to raise temperature indoors. Used in ow latitudes, colored glass also called Sun-E glass, can sunshade to a certain degree at the time of preventing energy from out.
"Low-E Glass"refers to a series of high-performance, low-emissivity products manufactured by Rider Glass introducing state-of-the-art vacuum sputtering coating equipment.
The vacuum sputtering process coats glass surfaces with several layers of different materials. Among these, a silver layers effectively reflects infrared rays while maintaining excellent thermal performance. Beneath the silver layer is an anti-reflective tin oxide (Sn02) base layer that increases the transparency of the glass. Above 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-saving properties required of modern architectural glass and green building design.
It has good spectrum selectivity. could take over the near infrared ray and visible light from sun. could block off quite a few infrared ray going indoors. It not only keeps the light brightness indoors, and also decreases the heat load indoors. It has the advantages of saving energy, environment protection comfortable living and blocking the UV radiation etc.
