1, Excellent thermal properties:
The heat loss of exterior door and window glass is the main part of building energy consumption, accounting for more than 50% of building energy consumption. Relevant research data shows that the heat transfer on the inner surface of the glass is mainly radiation, accounting for 58%, which means that the most effective way to reduce the loss of heat energy is to change the performance of the glass. The emissivity of ordinary float glass is as high as 0.84. When a layer of silver-based low-emissivity film is coated, the emissivity can be reduced to below 0.15. Therefore, the use of Low-E glass to manufacture building doors and windows can greatly reduce the transfer of indoor heat energy caused by radiation to the outdoors, and achieve ideal energy-saving effects.
Another significant benefit of reduced indoor heat loss is environmental protection. In the cold season, the emission of harmful gases such as CO2 and SO2 caused by building heating is an important source of pollution. If Low-E glass is used, the fuel consumption for heating can be greatly reduced due to the reduction of heat loss, thereby reducing the emission of harmful gases. The heat passing through the glass is bidirectional. Low-E glass can meet the needs of winter and summer. It can not only keep warm but also insulate, and has the effect of environmental protection and low carbon.
2. Good optical performance:
Low-E glass has a high transmittance to visible light in sunlight, up to more than 80%, while the reflectance is very low, which makes its optical performance greatly improved compared with coated glass. From the outside, the appearance is more transparent and clear, which not only ensures the good lighting of the building, but also avoids the light pollution caused by the light reflection of the large-area glass curtain wall and insulating glass doors and windows in the past.
