Excellent Thermal Performance
The heat transfer loss of outside doors and windows is the main part of the buildings energy consumption, which accounts for more than 50%. Relevant research data shows that the heat transfer through glass is mostly by radiation, it occupies 58%. The radiation rate of common float glass is as high as 0.84,while it can be reduced to less than 0.15 when the glass surface is coated with a silver based low radiation film. Therefore, the building windows and doors which made of Low-E glass can greatly reduce the indoor heat transfer to the outside caused by radiation to achieve the desired energy-saving effect.
Another significant benefit of reducing indoor heat loss is environmental protection. In the cold season, the emission of harmful gases such as CO2, SO2 and so on caused by the heating of buildings is an important source of pollution. If use Low-E Glass, it can significantly reduce the fuel consumed by heating due to the reduction of heat loss, thereby reducing the emission of harmful gases.
Excellent Optical Performance
Low-E glass has a high transmittance of visible light, which is more than 80%, while the reflection keeps very low.
It be more transparent and clear when viewing from outdoor which not only ensures the good lighting of buildings, but also avoids the light pollution caused by large area glass curtain wall and hollow glass door and window.Creating a more soft and comfortable light environment.
