What is energy-saving glass? Energy-saving glass to have two energy-saving features - insulation and heat insulation. Glass insulation (K value) to achieve the level of matching with the local wall. For most of our country, according to the existing regulations, the building wall K value should be less than 1, therefore, the glass window K value should be less than 1 to "block" building "opening" energy loopholes. In the energy-saving windows, the glass of the K value plays a major role. The glass for the insulation (shading coefficient S) and the location of the building to adapt to the characteristics of solar radiation. Different requirements of the building on the glass insulation is different. For people living and working in residential and public buildings, the ideal of the glass should make most of the visible light through, such as in Beijing, the best infiltration of indoor infrared in winter, while the summer is less penetration into the room, so you can achieve energy saving purpose.
What glass can be called the ideal "energy-saving glass"? At the same time to achieve the above "insulation" and "insulation" requirements are Low-E insulating glass and multi-insulating glass and are emerging Low-E vacuum glass and vacuum glass combination. Low-E glass (low-E glass) has been developed and popularized for several decades, including glass, heat-absorbing glass, heat-reflective glass, and Low-E glass. ) Of the sun's best, it prevents the infrared light into the room, but also maintain a certain visible light transmittance, with a reasonable spectral transmission performance. At present, the world's low-E coated glass consumption has more than 150 million square meters, in recent years, the use of domestic construction has also shown a rapid increase in the trend.
