Noise pollution is getting worse these days, not only affecting mood and hearing, but also causing high blood pressure, heart disease, memory loss, difficulty concentrating and other psychiatric symptoms.

Studies have shown that human hearing can accept a volume of up to 30 decibels. When the continuous noise pollution in the room exceeds 30 decibels, normal sleep will be disturbed, while living in a noise environment of more than 70 decibels continuously, human hearing and body. Health will be affected.

In order to improve the noise problem, many people install soundproof glass. Today, we will explain in detail the 5 issues that everyone is most concerned about about soundproof glass.

What is soundproof glass?

Sound insulation glass is a kind of glass product that plays a certain role in shielding sound. It is usually a laminated glass with a double or multi-layer composite structure. The sound insulation damping glue (film) in the middle plays a key role in the weakening and attenuation of sound transmission.

What is the function and classification of soundproof glass?

At present, the more common ones on the market are insulating glass, vacuum glass, laminated glass, etc.

insulating glass

Insulating glass is composed of two layers of glass, which uses air to partially absorb the energy of medium and high frequency sound vibration, thereby reducing the sound level of sound waves. The sound insulation effect is relatively weak, with a maximum of only ten decibels.

vacuum glass

Vacuum glass is to seal the two pieces of flat glass around, vacuumize the gap and seal the exhaust hole. The gap between the two pieces of glass is 01-02mm. Generally, at least one of the two pieces of vacuum glass is low-emissivity glass. This minimizes heat loss through conduction, convection and radiation through the vacuum glass.

Laminated glass

This kind of glass is a relatively popular and professional soundproof glass in the current soundproof window market. Laminated glass is generally composed of two layers of glass and film, and the two layers of glass are made of different materials, which can block sound waves of different wavelengths.

The film in the middle of the laminated glass is equivalent to a damping layer, which can effectively suppress the vibration of the glass, thereby improving the sound insulation performance of the glass. And the glass thickness is not large, the density is high, the higher the density of the laminated glass, the better the sound insulation effect.

What is the price of soundproof glass?

This is the market reference price in December 2019, and the actual purchase may fluctuate due to various factors.

Precautions for installing soundproof glass?

Generally speaking, soundproof glass is half heavier than ordinary insulating glass. If the width of the window is too large, it is easy to deform the hanging angle and cause the seal to fail. Therefore, the best window width of the soundproof window is 35-65 cm. The width is about 50, 55, 60 cm, which is determined according to the specific conditions of the site.

If there is no original window during installation, it is necessary to consider that the color of the profile and the structural style of the soundproof window should be consistent with the entire building, otherwise it will affect the appearance of the entire building and will be interviewed by the property management company.

The original window can be dismantled or not, but it has better sound insulation effect if the original window is not removed. If the original window is not removed, it will be quieter by about 2 decibels. Therefore, it is generally not recommended to remove the original window.

What are the precautions for using soundproof glass?

①After installing the soundproof glass, tear off the protective film on the surface of the profile in time and scrub it clean, otherwise a large amount of the protective film adhesive will remain on the profile, which is difficult to clean.

②When the casement top-hung window is in use, different openings are achieved by changing the direction of the switch handle. It is necessary to understand how to operate it to avoid damage.

③ When the sliding soundproof window is in use, the sliding track should be cleaned frequently to keep it clean to ensure that there is no dust accumulation on the surface of the track and in the groove.
