4. What are the advantages of plastic steel window?
1. Energy saving, plastic doors and windows are more energy-saving than other doors and windows, which can effectively improve the indoor temperature environment. According to the test, the heat transfer coefficient of single-layer FRP aluminum window is about 64, that of single-layer FRP steel window is about 47, that of common double-layer FRP aluminum window is about 7 and that of double-layer FRP steel window is about 5. It can be seen that plastic steel doors and windows have a good energy-saving function.
2. The sound insulation effect is good. The sound insulation performance of plastic steel doors and windows is about 19 decibels, and the sound insulation performance of plastic steel doors and windows can reach more than 30 decibels. Living in an increasingly noisy urban environment, it is very appropriate to choose to use plastic steel doors and windows. More importantly, plastic steel doors and windows can improve the quality of people's living environment.
