1、 Sound insulation performance: the sound insulation performance of the window mainly lies in the sound insulation effect of the glass which accounts for about 80% of the window area. The gap sealing level of aluminum alloy doors and windows is basically the same as that of plastic steel doors and windows, and their sound insulation performance is also basically the same. Shanghai Academy of Building Sciences has carried out a series of measurement and comparative experiments on the sound insulation performance of plastic steel doors and windows and aluminum alloy doors and windows. The sound insulation loss of single glass plastic steel doors and windows with the thickness of 6 〉 5mm is about 21 ~ 24dB, and the sound insulation performance of 5 + 12a + 5 is hollow The sound insulation loss of plastic steel doors and windows with single frame and double glass is 24 ~ 29dB, and the sound insulation loss of double glass is about 5dB larger than that of single glass. Under the same glass thickness, structure and sealing condition, the weighted sound insulation loss RW value of plastic steel doors and windows and aluminum alloy doors and windows is similar

2、 Wind pressure resistance and water tightness: due to the low strength and rigidity of plastic steel doors and windows, the wind pressure resistance and water tightness of plastic steel doors and windows are about two grades lower than those of aluminum alloy doors and windows, although they are strengthened by adding lining stiffness. This is the case with the standard sample window submitted by the enterprise for inspection, and so is the sample taken from the construction site. Shanghai building curtain wall testing center adopts witness sampling method to install aluminum alloy doors and windows and plastic steel doors and windows
