It is understood that compared with developed countries, China's energy-saving doors and windows industry is still in its infancy. At present, in developed countries, the proportion of high-performance energy-efficient doors and windows has reached 70% of total. While in China, the high-performance system windows and doors only reached 0.5% of the total.
China Construction Metal Structure Association energy-saving doors and windows Commission data shows that the current domestic manufacturers of doors and windows have more than 10,000. Insiders said that Beijing took the lead in the country to take 75% of building energy-saving measures, which has a very positive impetus of the development of the energy-saving doors and windows.
Development bottleneck - a breakthrough of technology innovation
Energy-saving doors and windows are not green
We need to understand the current problems of windows and doors industry. It is essential for the future development of the industry. Energy-saving doors and windows are not green. A lot of doors and windows in the building can play a role in energy conservation, but the door and window materials can produce high energy consumption. High consumption has high pollution.
Green windows and doors are not energy-saving
However, green windows and doors are not energy-saving. In the green energy saving doors and windows material production process, the energy savings are relatively poor. Such as single-glazed plastic windows, there is no emphasis on overall performance, including green profiles, green glass, and the whole window climatic adaptability.
Green energy-saving doors and windows are not safe
We cannot deny that due to process, cost and other factors, the production of energy-saving doors and windows have low intensity, deformation, poor durability problems. They cannot be used in high-rise buildings. So we need to set a good standard, which can lead to increased levels of the entire market.
