Type of LOW-E Glass
1 Online LOW-E glass(hard coated LOW-E Glass), is manufactured during production with a thin metallic oxide layer, effectively welding it to the hot glass surface. This process bring a extremely durable hard coat.
2 Offline LOW-E glass(soft coated LOW-E Glass). The coating is applied to the glass which have been formed. The quality glass enters a vacuum chamber which is full of inert gas. In the vacuum chamber, the metal molecules sputter on the glass surface, formed soft-coat.
There are single silver LOW-E glass, double silver LOW-E glass and triple silver LOW-E glass. All have many layers on the glass surface, inside the silver layer plays an important role on the performance.
1 Superior efficiency in energy saving. LOW-E Glass helps to reduce heat gain or loss, have an excellent energy-saving performance.
2 Excellent thermal performance. Compared to normal glass, LOW-E glass could reduce the heat around 30% which is conducted through glass. For double glazed windows, with LOW--E coating and proper frame, compared to 3mm standard glass, it can stop up to 70% heat loss and 77% of heat gain.
3 Good optical performance.LOW-E glass have high transparent to visible light, could avoid the glare problems and light pollution, which caused by the reflection.
4 Achieve a desired comfortable house. LOW-E glass can reach the required technique parameters, such as required SHGC(solar heat gain coefficient),U-Value, and visible light transmittance, bring a comfortable room.
