How many kinds of soundproof glass?


In fact, all soundproof glass can not remove noise by 100%. Generally, soundproof glass is divided into four types: insulating glass, insulating glass, vacuum glass, three-layer composite sound-insulating glass, and laminated glass sound-insulating glass. These four have their own characteristics in terms of sound insulation.


The insulating glass is filled with a desiccant in the middle to ensure the drying of the air. It has good insulation and heat insulation. It is widely used in architectural glass. However, insulating glass is not ideal for sound insulation with low frequency noise. Because the insulating glass will resonate with low frequency noise in the low frequency region. For high-frequency noise, the sound insulation effect is really good (such as vocals, tweeters, etc.).

The laminated glass is a safety glass. Laminated glass has good sound insulation, but it is also flawed. However, laminated acoustic glass will have different effects due to the different technical content of the manufacturer. If the professional soundproof glass is in the middle with a soundproof damping rubber. It plays a key role in the filtering of sound and the weakening of propagation. Professional soundproof glass can achieve a sound insulation of 30-40 decibels.


Vacuum glass is generally composed of two or three layers of flat glass. Generally, a gap of 1.5 mm is left in the middle to evacuate. At the beginning, vacuum glass was originally designed for thermal insulation. However, it should be noted that the insulating glass is not necessarily a vacuum sound-insulating glass, and the vacuum sound-insulating glass can achieve the effect that other sound-proof glass cannot achieve.


Three-layer composite acoustical glass is generally made up of a combination of insulating glass and laminated glass or vacuum glass. Because of this, the advantages of the three-layer composite sound-insulating glass make it a new type of sound-insulating glass. The first layer is windproof, the second layer is energy efficient, and the third layer is soundproof and energy efficient. In the face of low-frequency sound insulation performance is very good.
