In modern architecture, the sound insulation of windows is very important. It not only ensures quiet indoors, but also effectively blocks out outside noise. At present, there are two common soundproof glasses on the market: laminated glass and insulating glass. So, which is better sound insulation, laminated glass or insulating glass? This article will make a detailed comparison of the structure, principle and practical application of the two.
First, let's take a look at laminated glass. Laminated glass is made of one or more layers of PVB (polyvinyl alcohol) film sandwiched between two or more pieces of glass, which are treated with high temperature and high pressure. PVB film has a good sound insulation effect and can effectively prevent the propagation of sound. In addition, laminated glass also has good explosion-proof properties, even if the glass is broken, it can maintain its integrity and will not cause harm to people.
Then, let's take a look at insulating glass. Insulating glass is a closed air layer formed between two or more pieces of glass, and the air layer can effectively absorb sound, so as to achieve the effect of sound insulation. The sound insulation effect of insulating glass depends mainly on the thickness and tightness of the air layer. The thicker the air layer, the better the sound insulation; The better the sealing, the better the sound insulation.
From the perspective of sound insulation, laminated glass and insulating glass have their own advantages. The sound insulation effect of laminated glass mainly depends on the thickness of the PVB film, the thicker the PVB film, the better the sound insulation effect. The sound insulation effect of insulating glass mainly depends on the thickness and tightness of the air layer, the thicker the air layer, the better the sealing, and the better the sound insulation effect. Therefore, if you only look at the sound insulation effect, the sound insulation effect of laminated glass and insulating glass is comparable.
However, from the practical point of view, there are other factors that need to be taken into account in the selection of laminated glass and insulating glass. For example, laminated glass, although it has a good sound insulation effect, is relatively high, and the installation process is more complicated. The ** of insulating glass is relatively low, and the installation process is relatively simple. In addition, laminated glass also has good explosion-proof properties, while insulating glass does not.
In general, laminated glass and insulating glass have good sound insulation, but when choosing, it also needs to be considered according to actual needs and budget. If you have a sufficient budget and high safety requirements, you can choose laminated glass; If you have a limited budget or don't have high safety requirements, you can opt for insulating glass.
