Understanding Soundproof Glass: Manufacturing Properties and Applications

There are various types of glass used for windows in residential as well as commercial areas. These glasses have different properties and are installed for different purposes. Among them is soundproof glass which has become highly popular in both homes and offices as it helps to reduce the surrounding noise and gives you complete peace and privacy. There are a lot of people who opt for soundproof glass in their homes or offices, however, there are still a considerable number of people who have doubts regarding the usefulness and importance of soundproof glass. In this article, we will discuss at length soundproof glass and understand how it works. We will also discuss the manufacturing properties and applications of soundproof glass.

What is Soundproof glass?

As the name suggests, soundproof glass is basically glass that won’t allow surround sound to pass through it, thus eliminating all the disturbing sound from outside and allowing complete peace. In more technical terms, soundproof glass is any glass that is manufactured by joining two layers of glass with an interlayer of polyvinyl Butyral or PVB in between them.

The interlayer of PVB is quite significant in the manufacture of soundproof glass as it is what bonds the glass sheets together and gives them a single-paned appearance. The most common type of glass that is used for soundproofing is laminated glass.

When soundproofing glass, it is first tempered and toughened to make it stronger and harder. This ensures that the glass doesn’t break easily. The standard thickness of a single unit of soundproof glass needs to be 12 mm. This 12 mm thickness will provide you with 20 dB of noise cancellation, thus making the glass a good quality soundproof glass.

There are usually two types of soundproof glass-

  1. Double-glazing soundproof glass: It has both soundproofing and insulating qualities.
  2. Laminated glass: It has both soundproofing and security properties.

What is the need for soundproof glass?

The continuous honking and traffic sound while you are studying or working, or the sound of loud annoying music while you are sleeping can really get on your nerves. But what if you can prevent this from happening by reducing these annoying sounds so that you can focus on your work or enjoy a nice afternoon nap? Now that would be like a dream come true, won’t it? Well, you don’t have to just dream about it if you have soundproof glass installed in your home or office windows.

With its soundproofing qualities, the glass dampens the soundwaves that fall on it and reflects them back to their original source. This means that the sound can’t pass through the glass, thus keeping you safe from the loud noise and sound vibrations that have more negative effects on your health than you can think of.

As far as the need for soundproof glass goes, it is important that you know that loud noise does much more harm than just disturbing you. Research has shown that noise pollution is one of the main causes of stress, fluctuating blood pressure, irritability, loss of memory, and many other psychological and physical problems. This is why soundproofing your windows has become kind of necessary in this day and age.

Manufacturing Process of Soundproof glass

As we discussed above, there is a certain way in which soundproof glass is manufactured to make sure that it has all the soundproofing qualities to cancel the outside noise. Some of the manufacturing properties of the soundproof glass are as follows:

  • Soundproof glass is made with two layers of glass that are bonded together with an interlayer of Polyvinyl Butyral or PVB.
  • The PVB interlayer helps to keep the two layers of glass together and gives it a single-paned appearance.
  • The PVB interlayers also help to dampen the noise and weaken the energy of the sound waves when they travel through the glass.
  • The soundproof glass provides insulation to the window frame and prevents any noise from passing through.
  • Two types of soundproof glasses are manufactured— double glazing soundproof glass and laminated soundproof glass. The double-glazing soundproof glass has soundproofing and insulating properties, while the laminated soundproof glass has soundproofing and security properties.
