What are the characteristics of plastic steel windows?

1. The plastic steel window has good air tightness. Plastic steel doors and windows are equipped with rubber and plastic sealing strips and wool strips at all gaps during installation.
Therefore, its air tightness is much higher than that of aluminum alloy doors and windows. The air tightness of plastic steel casement windows is higher than that of sliding windows.
Generally speaking, the air tightness of casement windows can reach four levels, and the sliding windows can reach three levels.
​​
2. Plastic steel windows have good weather resistance. The plastic-steel profile adopts a unique formula to improve its cold resistance. Steel doors and windows
It can be used in environments with large temperature difference (-50℃~70℃) for a long time, and it will not change due to sun exposure and humidity.
quality, aging, embrittlement and other phenomena, the earliest plastic steel doors and windows have been used for 30 years, and their materials are as good as before.
Calculated, under normal conditions, the service life of plastic steel doors and windows can reach more than 50 years.
​​
3. The water tightness of the plastic steel window is good. Due to the unique multi-cavity structure of the plastic-steel profiles, all have independent drainage
The cavity, whether it is the frame or the fan, the water can be effectively discharged. The water tightness of plastic steel casement windows is much higher than that of sliding windows.
Under normal circumstances, the water tightness of casement windows can reach five levels, and the sliding windows can reach three to four levels.
