How Thick Is Soundproof Glass (Know All The Types)

Among all the soundproofing materials, soundproof glasses are the most effective ones. Soundproof glazing can reduce noise up to 36db. However, the effectiveness of these glasses might make you think, how thick is soundproof glass?

Soundproof glass is available in various thicknesses, from 6.4-12.8mm thick. In addition, thicker acoustic glass is available (up to 20.8mm). The thickness of the glass affects its ability to block sound, and the type of acoustic glass will also affect its cost. Acoustic glass is available in a variety of colors and customizable sizes.

However, the thickness of the glass also varies depending on its type and several other factors. In this article, we will discuss all those factors related to the thickness of soundproof glazing, mentioning different types and working processes of acoustic glasses.

What Is Soundproof Glass?

Soundproof glass is a type of window film designed to reduce the noise and sound coming through it. Soundproofing is essential in any home or office that wants to keep its occupants safe and sound and soundproof glass efficiently blocks the sound from entering. 

Soundproof or acoustic glass is made from glass that has been laminated with hinged glass referred to as “pie glass.” The PVB or polyvinyl butyral interlayer intertwines with the glass sheets, making the glass shatterproof.

These glasses absorb sound waves so people cannot hear them within the room. While most soundproof glass ranges from about .03 inches to .06 inches thick, there are also specialized types made for metal studs and double-pane windows that range from about .025 inches to .045 inches in thickness. The thicker acoustic glass is more soundproof than windows with thinner acoustic glass. However, thicker acoustic glass also costs more.

Soundproof glasses are made of many materials, but tempered glass is the most common. Tempered Glass comprises several layers of glass that have been treated with heat and pressure to make them stronger.  

The thickness of soundproof glass varies depending on the material it is made from, and the frequency of the sound is reduced. Generally speaking, thicker soundproof glass will reduce high-frequency sounds more than lower-frequency sounds.

How Does Soundproof Glass Work

Soundproof glass erects a barrier of sound between the source and your ears. It filters out the acoustic vibrations recognized and swallowed by the glass and traps them. This system can detain up to 90 to 95 sound vibrations insisting that you preserve an awareness of very few noise frequencies.

The sonic energy created by outside noises travels through the air and hits the surface of acoustic glazing. The pressure waves cause the acoustic glazing to vibrate, producing sound deadening. In most cases, acoustic glazing can reduce exterior noise by up to 50%. 

The main difference between acoustic glazing and other types of soundproofing is that acoustic glazing uses sound waves to block noise rather than silence it. This means acoustic glazing can be more effective at reducing noise levels than other soundproofing types, such as foam or fabric-covered walls. 

One downside of acoustic glazing is that it cannot eliminate all sounds from entering the building. In addition, acoustic glazing can be expensive and may not be suitable for all types of buildings.

How Thick Is Soundproof Glass

Soundproofing your windows is essential to maintaining a healthy environment for you and your family. There are mainly two different types of soundproof glass, each with its benefits. Here is a brief overview of the different types of soundproof glass and their benefits:

Double Glazing (Pairlex Soness Neo)

The Double Glazed Glass (Pairlex Soness Neo) is heat insulating and has a thickness of 20mm to 24mm. It is best for industrial use as it has excellent insulation properties. It is widely used in industry, commercial and domestic applications. 

Also, It is perfect for use in the home or office. The efficiency of Double Glazed windows is excellent as there is an air gap between the glass and the frame to provide insulation. Double-glazed windows are very efficient in keeping the heat in and the cold out. This is because the air passing through the window is forced to pass through a layer of cold air before entering the room. It dramatically reduces the amount of heat loss in winter and therefore increases heating costs. 

Laminated Glass (Lamilex Soness)

Laminated glass is a type of window made up of two 1.8 mm thick sheets of glass. The thin layer (typically 0.76 mm thick) of polyvinyl butyrate makes it a good choice for home use, as it resists scratches and breaks. 

This type of window is also resistant to cracking and breaking. A laminated glass window is a good option for people who live in temperate areas. It is also a good choice for people who do not want to spend much time cleaning the window. Laminated glass is a type of window made up of two 1.8 mm thick sheets of glass. The thin layer (typically 0.76 mm thick) of polyvinyl butyrate makes it a good choice for home use, as it resists scratches and breaks. 


soundproof glass is effective at reducing the noise levels coming from outside sources, but it is not as thick as other types of glass, so it does not entirely block the sound waves you can use soundproof curtains beside the acoustic glazing. All in all, merchants and homeowners should consider their needs before making a purchase, and those with noise-sensitive jobs should consult with an acoustic engineer to see if soundproofing is the right solution for them.
