People nowadays prefer large-size window for sightseeing or for enjoying sunshine to relax. However, the heat runs off through the window at the same time. í¦It is not easy to make the best of both worldsí¦!í¡í¡Now ,the low-E glass appears to settle this problem. It has a high transmission of visible light and can reflect infrared heat at the same time, which can satisfy most people and architectures. The Low-E glass has the same coating principle as solar-control glass, but differs from them in material , the structure layer is also more complex ,demanding for equipment with super throughput and excellent accuracy in process control. The characteristic of Low-E glass is achieved by the silver layer. The oxidation of silver can result in the disappearance of low-E performance ; therefore ,low-E glass cannot be single used in the air ,which means it can only be made into combined glass. Color: Varying tones such as transparent, shallow gray, silver gray, green blue etc. Specification: Max size: 2540mmí-3760mm Mini size: 300mmí-800 mm Thickness: 5mm~19mm Feature: With high transmission of visible light, low reflectivity and low emissivity (e
