Acoustic Double Glazing for Soundproof Windows Doors

Acoustic double glazing

Sound insulation glass is a kind of glass product that has a certain shielding effect on sound, usually a laminated glass with a double-layer or multi-layer composite structure.

The sound insulation damping glue (film) in the middle of the laminated glass plays a key role in the weakening and attenuation of sound transmission. The glass products with sound insulation function include laminated glass.

Ordinary glass is a single-layer structure, which is a layer of glass from the inside to the outside.

The difference between the isolation glass wall and the ordinary glass wall on the market lies in the panel of the glass, and the sealing material and method between the aluminum profile and the glass.

According to the difference in the middle part of the soundproof glass wall, it can be divided into four categories, namely: insulating glass, vacuum glass, laminated glass and double-layer structural glass.

The difference between soundproof glass and ordinary glass

In the noisy community, many places and owners’ homes will install soundproof glass, which can reduce noise interference to a certain extent.

So, what is the difference between soundproof glass and ordinary glass?

Is soundproof glass useful?

The soundproof glass is composed of double or triple layers of glass with different thicknesses, which effectively control the “matching effect” and form sound insulation valleys.

In addition, the sound-absorbing material is filled in the window frame, which effectively absorbs the sound waves of the transparent glass, so that the noise of each frequency band is effectively isolated.

The sound insulation glass uses a specially processed sound insulation layer. The sound insulation layer is made of PVB film which is firmly bonded by high temperature and high pressure.

Depending on indoor and outdoor noise conditions, 80 decibels of traffic noise can be reduced to extremely quiet levels below 45 decibels. When the sound passes through the soundproof window,

After eight layers of medium reflection and reduction, the sound insulation effect is good, and the sound insulation effect is reduced by more than 10 decibels on the basis of ordinary sound insulation windows, generally reaching 40 decibels.

For soundproof glass with qualified installation process, its sound insulation effect is still very obvious, so soundproof glass is useful.

Principle of soundproof glass

(1) All kinds of outdoor sounds are generated by vibration, noise is transmitted through the air medium, and doors and windows also transmit sound into the room through vibration,

Therefore, as long as the vibration of doors and windows can be controlled and adjusted as needed, the effect of sound insulation can be achieved.

This vibration produces sound, and vibration is a physical phenomenon that stimulates hearing.

Hearing occurs when vibrations with a frequency of 15-20,000 Hz reach the inner ear.

(2) When the noise is transmitted to the soundproof glass doors and windows, and then attenuated by the soundproof glass, especially when the noise passes through the soundproof damping glue,

The medium frequency noise and high frequency noise are absorbed, twisted, damped and attenuated by the sound insulation damping glue, which can effectively filter out the medium and high frequency noise.

After entering the room, the noise is only about 5%.
