Energy saving: Plastic steel doors and windows have a low heat transfer coefficient and good thermal insulation performance. For example, the heat transfer coefficient of a single glass plastic steel window is approximately 47W/M2K, while the heat transfer coefficient of a double glass plastic steel window is approximately 2.5W/(m2 · K) 3.
Sound insulation: Plastic steel doors and windows have better sound insulation performance than doors and windows made of other materials. The experimental results show that the sound insulation effect of plastic steel doors and windows can reach over 30 decibels.
Impact resistance: Due to the aluminum alloy outer surface of the aluminum-plastic composite profile of plastic steel doors and windows, its impact resistance is stronger than that of pure plastic steel window profiles.
Air tightness and water tightness: Plastic steel doors and windows have good air tightness and water tightness, which can effectively prevent the penetration of air and moisture. For example, aluminum-plastic composite windows are equipped with multiple sealing strips or rubber strips at each gap, with a first level air tightness, which can fully utilize the air conditioning effect and save 50% of energy.
Fire resistance: Plastic steel doors and windows are usually made of non self igniting and non combustible UPVC materials, which have good fire resistance
