Aluminum-plastic co-extruded profiles will become the mainstream of green energy-saving doors and Windows

From the "Twelfth Five-Year Plan" energy conservation plan that has been introduced by the state to the relevant local standards such as the K value of doors and Windows proposed by Beijing, it can be seen that the awareness of energy conservation in China is gradually improving. However, like other industries in the development of the green building industry chain, the energy-saving doors and Windows industry also needs to precipitate its own energy-saving effectiveness.

Many doors and Windows can play an energy-saving role in building, but the production of doors and Windows materials has high energy consumption, high consumption and high pollution. For example, the familiar broken bridge aluminum alloy, Low-E glass Windows, etc., are not green in the selection of profiles. Compared with aluminum-plastic co-extruded profiles with the same properties, the amount of aluminum alloy per unit window area is 2 ~ 3 times higher than that of aluminum-plastic co-extruded Windows, and the production energy per unit window area is 1.3 times higher than that of aluminum-plastic co-extruded Windows. The coating process of energy-saving glass will consume a lot of water and electricity in the production process, and will discharge industrial dust.

Green doors and Windows do not save energy The production process of green doors and Windows materials saves energy and reduces consumption, but the energy-saving effect is relatively poor. For example, single-layer glass plastic Windows do not emphasize the comprehensive performance, including green profiles, green glass, and the climate adaptability of the whole window.

Green energy-saving doors and Windows are not safe can not be denied, some enterprises due to process, cost and other factors, the production of energy-saving doors and Windows have low strength, deformation, poor durability, can not be used in high-rise buildings.
