Nowadays, the noise of urban life is everywhere, especially in the community near the road, train and airport. Consumers generally change their windows and choose broken bridge aluminum doors and windows. Many consumers even require to make three-layer glass of broken bridge aluminum. Is this kind of glass used for sound insulation?
After testing, in fact, the sound insulation effect of three-layer glass is not as good as that of double-layer glass, and the difference between the two is not very big. Many consumers have gone into a misunderstanding that if you want to sound insulation well, you should add one more layer of glass. In fact, if you add a layer of glass, you can't choose three-layer insulating glass, but you should choose the combination of laminated glass and insulating glass This can effectively isolate low, medium and high frequency noise.
Automobile, train, airport noise are low-frequency noise, three-layer insulating glass is not the most ideal choice of sound insulation glass, but should choose the combination of laminated glass and insulating glass, which is the most ideal sound insulation glass. Whether it is low-frequency noise or medium and high-frequency noise, this combination of glue and hollow is the most perfect. Our aluminum alloy door and window manufacturers call this kind of glass It is laminated insulating glass.
Compared with the insulating glass window, the laminated insulating glass window can control the low-frequency noise more obviously, and can prevent the noise pollution caused by the resonance of the window caused by low-frequency noise. Laminated insulating glass window is a kind of sound insulation window with good sound insulation effect and mature production technology in the market. Compared with other glass, laminated glass has the performance of shock resistance, anti-theft, bullet proof and explosion-proof. The glass of bank window is the laminated glass.
Many door and window manufacturers boast that the three-layer insulating glass is better than the double-layer glass in sound insulation, which is not absolute. Some consumers still can not achieve the sound insulation effect they want after spending a high price. The sound insulation of three-layer insulating glass and double-layer insulating glass is similar.
