What kind of glass has better soundproof effect? Insulated glass or laminated glass? Below, we will conduct a detailed analysis from the characteristics, soundproof principles, application scenarios, etc. of insulated glass and laminated glass.
Insulated glass is separated by a sealant strip or sealant frame between two or more pieces of glass, forming an air layer in the middle. The design of this structure causes the sound to be hindered by the air layer during the propagation process, thereby reducing the transmission of sound. The soundproof effect of insulating glass mainly depends on the thickness of the air layer, the thickness of the glass and the sealing performance. Generally speaking, the thicker the air layer, the better the soundproof effect. However, it should be noted that the soundproof effect of insulating glass on high-frequency sounds is relatively good, while the soundproof effect on low-frequency sounds is relatively weak.
Therefore, insulated glass is more suitable for noisy environments because it has a better soundproof effect on high-frequency sounds and can effectively isolate the sounds of traffic and people on the street.
Laminated glass is made by sandwiching one or more layers of organic polymer interlayer films between two or more pieces of glass, and is processed by high temperature and high pressure. The design of this structure causes the sound to be hindered by the intermediate film during the propagation process, thereby reducing the transmission of sound. The soundproof effect of laminated glass mainly depends on the material and thickness of the interlayer film and the thickness of the glass. Laminated glass has a relatively good sound insulation effect on low-frequency sounds, because low-frequency sounds have longer wavelengths and are more easily hindered by the interlayer film.
Therefore, laminated glass is more suitable in environments with a lot of low-frequency noise, such as factories and workshops. Because it has better soundproof effect on low-frequency sounds, it can better isolate the sound of machine operation, equipment vibration, etc.
In addition, when choosing insulating glass or laminated glass, other factors need to be considered, such as thermal insulation performance, wind pressure resistance, safety, etc. For example, insulated glass has good thermal insulation performance and is suitable for colder areas in winter; while laminated glass has high wind pressure resistance and safety performance, and is suitable for high-rise buildings or places that require explosion protection.
In summary, insulated glass and laminated glass each have their own advantages in soundproof, and which one to choose depends on the specific use environment and needs. When choosing, in addition to considering the soundproof effect, you also need to consider other factors in order to choose the type of glass that best suits you.
