Doors and windows are important structures for building openings. People's demand for doors and windows from the previous only lighting and ventilation needs, to now the development of urbanization brought a series of problems on doors and windows put forward new requirements, the most instinctive is the noise of doors and windows. According to relevant statistics, 90% of external noise comes from doors and windows, because the thickness of doors and windows is smaller than the wall, the sound insulation effect is far less than the wall. The sound insulation effect of doors and windows mainly depends on aluminum profiles windows & doors, glass material structure, sealing treatment, etc.
Fan frame material structure
Aluminum profiles windows & doors structure, each cavity is closed, so that the door and window sealing effect is better. In particular, the broken bridge multi-cavity profile structure can reduce the thermal conductivity of metal, and the quality and quantity of the sound insulation bar, the higher the wall thickness of the cavity, the higher the elasticity of the sound insulation bar, the better the sound insulation effect will be.
Glass texture
Now in the market mainly hollow glass, laminated glass, vacuum glass and so on. If the floor is above 20 floors and there is no train or large trailer nearby, insulating glass or laminated glass can be considered. If the floor is low and close to the road or the viaduct and there is a low frequency noise source nearby, then vacuum glass or composite three-layer soundproof glass should be considered.
Sealing treatment
In addition to aluminum profiles windows & doors and glass with sound transmission considerations, gaps throughout the window are also one of the paths of sound transmission. The better the sealing of the doors and Windows, the more effective it will be to prevent sound from entering the room from the gap. Sealing rubber strip is an important structure connecting glass and window sash, window sash and frame body. The quality of sealing treatment can not be ignored. Bad treatment will give the noise an opportunity.
