What are the five characteristics of plastic steel windows?

1. Plastic steel window has strong machinability. In the molten state, plastic has high fluidity, so it can form an accurate cross-sectional structure through the mold, thus realizing the functional requirements of the window. But also a compartment can be formed, so that the functions of heat preservation, sound insulation and drainage of the window are improved, and the corrosion of steel bars is avoided.

2. Energy-saving plastic steel window Plastic steel window has better technical characteristics than other windows in saving energy and improving indoor thermal environment. According to the test by the Institute of Physics, the heat transfer coefficient of a single FRP aluminum window is 64 W/m2k; The heat transfer coefficient of single-layer glass-plastic steel window is about 47W/M2K；; The heat transfer coefficient of steel-aluminum window with common double-glazing is about 3.7W/(m2 k). The heat transfer coefficient of double-layer glass-plastic steel window is about 2.5 W/(m2 k). Windows account for 30% of the building envelope area, and its heat dissipation accounts for 49%. Therefore, plastic steel windows have good energy-saving benefits.

3. Sound insulation performance of plastic-steel windows The sound insulation performance of steel-aluminum windows is about 19 dB, and the sound insulation performance of plastic-steel windows can reach more than 30 dB. In the increasingly noisy urban environment, the use of plastic steel windows can make the indoor environment more comfortable. According to the data provided by Japan, to achieve the same noise reduction requirements, the distance between the aluminum window building and the main traffic road must reach 50 meters, while the plastic steel window should reach 18 meters. According to the detection of Beijing Institute of Labor Protection, the indoor noise of plastic steel window is reduced to 32DB(A), and the effect is very good. Due to the development of economy, the problem of urban noise is becoming more and more serious. Plastic steel windows will make great contributions to improving the acoustic environment quality of people's lives and work. In addition, the plastic steel window is corrosion-resistant and can be used in corrosive environments such as coastal areas and chemical plants, and ordinary users can also reduce the labor and cost of maintaining paint.

4. The appearance of plastic steel window can meet the requirements of home decoration effect, and the human body feels more comfortable than metal. Due to the above outstanding advantages, plastic steel windows have been widely used in China and become a new trend in the field of architecture.

5. The cost of plastic steel window is low. The cost of plastic steel windows with the same use efficiency is 30%-60% lower than that of aluminum alloy windows, which is the main reason for the popularization of plastic steel windows.
