Glass Wool To Improve Sound Insulation

Several materials can improve the sound insulation of your home.  Why choose glass wool? Read this article to learn more about this material.

What Is Acoustic Glass Wool?

Glass wool is an insulation material used to improve the thermal and acoustic insulation of a home. Made from glass melted at 1,450°C, this material has a strength approaching that of angel hair.

What Are the Different Sizes of Glass Wool?

Glass wool comes in three different formats, namely:

-The glass wool in flakes: it is used for the insulation of lost attics. The technique used is blowing or projection.

-The glass wool in panels: generally speaking, this glass wool is presented in the form of a rectangular plate. It is available in different sizes, but we advise you to choose a 130 x 60 cm sheet.

Indeed, this size is not only a basic reference but also a standard size. The glass wool in panels is generally used to ensure the acoustic insulation of the ceiling or the partitions.

-Glass wool in rolls: in general, this glass wool has a width of 1 m and a length of 2 to 4 m. It is used to insulate the cladding and roof of a house acoustically.

What Are the Advantages of Glass Wool?

There are many advantages to choosing glass wool as a soundproofing material for your home. Here are some of them:

Incomparable Acoustic Performance:

Because of its very high acoustic performance, glass wool is considered the best insulator. It can easily absorb noise, thanks to the porosity of its structure and its elastic texture.

Applied on the facades and walls, this material allows attenuating the noises coming from the outside. Used on the ceiling or on the partitions, this insulation helps you soundproof the different rooms of your house.

The level of performance of glass wool depends significantly on the quality and thickness of the insulation chosen.

An Affordable Price:

Compared to other insulators, the price of glass wool is very affordable. However, this price can vary from one vendor to another and according to the size and thickness desired. On average, the cost of a 100 mm thick glass wool varies between 3 and 8 euros.

A Non-Combustible Product:

The glass wool is an incombustible insulator, and it is therefore not vulnerable to fire. This is why this material is more and more popular in France.

A Rot-Proof Product:

By opting for glass wool, you will save a lot of money because this material is rot-proof by nature. You won’t have to make repairs for decades.

No Health Risks:

This is one of the main advantages of glass wool. Indeed, it is made from environmentally friendly products. In case of fire, it does not give off toxic fumes, and therefore, it does not present any health risk.

What Noises Can Glass Wool Reduce?

Different types of noise can quickly be reduced by sound insulation. They are generally :

Impact noise: moving furniture, falling objects, clicking heels, etc.

Airborne noise from outside: rail traffic, road traffic, air traffic, etc.

Airborne noise from inside: television, radio, music, etc.

Equipment noise: ventilation, elevator, taps, heating, etc.
