Editor: liefan 10:00:01, November 11, 2019

With the introduction of the quality standard of building energy-saving broken bridge aluminum doors and windows, the new energy-saving standard products of bridge broken aluminum doors and windows are favored by the market. At present, Guangdong Province, Shanghai and other places have also issued local building energy-saving door and window standards, actively accelerating the pace of building energy conservation.

  

Although at present, China is in the peak period of building the standards of aluminum doors and windows with broken bridges. The annual building area is about 2 billion square meters, but more than 97% of them are high energy consuming buildings. It is estimated that by 2020, China's high energy consumption building area will reach 70 billion square meters.

Due to the implementation of the national industrial policy on the development of chemical building materials and the technical policy of building energy conservation, we should implement the principle of giving priority to the application of energy-saving plastic doors and windows in energy-saving doors and windows. However, not all plastic doors and windows in any area are energy-saving doors and windows. For example, the heat transfer coefficient of single glass plastic sliding window is 4.6w/m2 · K ~ 4.68w/m2.k. Can not meet the design standards of energy-saving buildings in Beijing area, in such areas can not be called energy-saving doors and windows.

  

At present, more than 90% of the existing buildings of more than 40 billion square meters in China belong to high energy consumption buildings. In high energy consumption buildings, the energy consumption of doors and windows accounts for nearly half. Industry insiders said that the key to building energy efficiency is the improvement of energy-saving technology for doors and windows. Therefore, new energy-saving doors and windows is the inevitable trend of market development in the future.

  

Under the promotion of building energy-saving policy, a large number of new environmental protection doors and windows energy-saving products such as aluminum alloy energy-saving doors and windows, glass fiber reinforced plastic doors and windows, aluminum plastic composite doors and windows are constantly emerging and new products emerge one after another. According to incomplete statistics, the market share of building energy-saving doors and windows has increased rapidly, accounting for 50% of the whole door and window market. Therefore, vigorously develop new energy-saving products of doors and windows, whether economic benefits or social benefits, are very huge.

1. New energy-saving standards for aluminum doors and windows with broken bridge and high-performance sealing technology around the curtain wall. Reduce the heat loss of air infiltration and improve the main physical properties of air tightness, water tightness, sound insulation, heat preservation and heat insulation. It has a great breakthrough in sealing material, sealing structure and indoor ventilation structure.   

New energy-saving glass and glass bridge products should have high performance. Focus on solving the structure temperature and impact resistance performance and installation technology of heat reflection and low radiation insulating glass, high performance safety insulating glass and economic double glass, so as to realize the scientific combination of heat insulation and effective utilization of solar energy.

3. Thermal insulation technology of special profile for bridge breaking aluminum alloy and special profile for galvanized color plate. Focus on solving the problems of localization of heat insulation materials and the safety of fire-resistant and harmful suffocating gas, reduce the cost of materials and expand the scope of popularization.
