At present, the proportion of energy-saving thermal insulation doors and windows in China only accounts for 0.5% of the total, and there is still a big gap compared with developed countries in Europe and America. Europe developed high-performance energy-saving insulation doors and windows as early as the 1980s. In 2003, the European door and window energy-saving standards stipulated that its K value is not more than 1.4, while the highest standard in China is that the K value is not more than 2.8. The key to building energy efficiency is energy saving in doors and windows. Therefore, there is still huge room for growth in building energy-saving door and window technology and promotion, and it is also an inevitable trend in market development.

At present, our energy-saving insulation doors and windows mainly use materials with good thermal insulation performance and good sealing performance. In addition to selecting the door and window materials with good insulation effect, the enterprise itself needs to strengthen the research and development of new resources as the door and window materials to satisfy the consumers. Diversified needs. Reasonable design can make energy-saving insulation doors and windows play a good energy-saving effect, guarantee high performance and high quality.

The quality of the quality not only directly affects the loss and retention of heat, but also determines the life of the doors and windows. The door and window installation technology determines whether the doors and windows can be easily used, etc. Its technical level is an important part of ensuring energy saving of buildings. It can be seen that energy-saving doors and windows are widely used in the construction industry, and energy-saving windows and doors are vigorously developed. Their economic and social benefits are extremely optimistic.
