[China Aluminum Network] China's building energy-saving and green building development, has gone through many years, many advanced energy-saving products and energy-saving processes are gradually used in China's construction industry, energy-saving insulation problems are particularly prominent in the building It is related to sustainable development issues such as resources, low carbon, and environmental protection. Doors and windows occupy an important position in the residential energy-saving system. At present, China’s building energy consumption accounts for over 27% of the total energy consumption of the entire society, of which the energy consumption of glass doors and windows accounts for about 40% of the building energy consumption. Therefore, it is imperative to choose energy-saving doors and windows for thermal insulation.
At present, there are three types of energy-saving doors and windows that are mainly used in the market. They are: plastic doors and windows, wear-bar insulated aluminum alloy doors and windows, and plastic-insulated aluminum alloy doors and windows. Judging from the current application situation, plastic doors and windows are mainly used in rural markets, some low-grade residential quarters and some buildings with low floors. The wearing of heat-insulating aluminum alloy doors and windows and plastic injection-insulating aluminum alloy doors and windows are the preferred choice for urban residences, business apartment buildings, and landmark buildings. Even some counties and villages and towns have gradually recognized such doors and windows.
