Low-E coated glass is a kind of glass on which surface layers of metals(included silver layer)or metallic compounds are sputtered.It has high visble transmission and high reflectance to infraded.Therefore, low-E glass can supply very good heat insulating performance and meet the requirement of energy saving by preventing overfull solar energy coming into room during summertime and reducing indoor heat loss during wintertime, The heat insulation performance of low-E glass is not represented until it is compounded into the insulating glass.
