How to choose your sound insulator

Acoustic insulation is essential for comfort and well-being. Dozens of models are currently available and correspond to various needs. To know which one corresponds to your expectations, choose by taking into account the following parameters

#1 - Usage

In order to choose the right insulator, you must first consider your needs. If the noises to be reduced are intense and frequent, you need an efficient and sufficient device to soundproof a recording studio. On the other hand, if you want to reduce impact noise or slightly reduce the sound environment, a standard foam insulator could be suitable. In short, it all depends on the degree of noise pollution you are exposed to.

#2 - Thickness

The thickness of a sound insulator is a parameter that determines its performance. The thicker it is, the better it will absorb impact noise and other unpleasant sounds. Generally speaking, a 3 cm thick model will provide good results. On the other hand, if you wish to have an optimal insulation, opt for a product of 5 cm thickness or more. This will guarantee perfect soundproofing.

#3 - Ease of installation

Soundproofing is a product designed to be easy to install. Generally speaking, there is no need to call in a professional to install them, except for mixed insulation. If you plan to install them yourself, choose synthetic polyurethane insulation. If you opt for natural insulation made of cork or cellulose wadding, the intervention of a professional is required.

#4 - Type of insulation

You will have the choice between two types of insulation: synthetic and natural. Users and professionals agree that synthetic insulation performs better than natural insulation. If you want to insulate finished walls or ceilings, it is wise to choose synthetic insulation. On the other hand, if the building is under construction, it's best to opt for both types of products.

#5 - Brand

There are dozens of manufacturers in the thermal insulation market today, and each has its own arguments to make. If you are hesitating between several insulators, make the choice between the most well-known brands such as Acouspanel, KeyHelm or Isover. It is always safer to choose brands that have already proven themselves.

How do you soundproof a room?

To achieve effective soundproofing, consider installing insulation at 3 key points in a room:

The walls

Insulating the walls will prevent unwanted noise from the neighborhood. To do this, you can opt for sandwich panels, masonry partition walls or the attachment of a framework between the ceiling and the floor. These techniques are very effective even when applied to a party wall.

Ceiling Insulation

If you are disturbed by the footsteps of neighbors or relatives living above you, opt for a soundproofing of the ceiling. You can opt for a glued sub-ceiling, the most commonly used technique at the moment, or suspended ceilings which create a mass-spring effect to absorb the level of footfall noise.

Floor sound insulation

If you want to insulate your floor so that you can move around freely without annoying the people living below you, opt for a thick covering to reduce impact noise. If you have the opportunity, cover the floor with a concrete slab, the best insulating device known today.

The different types of sound insulators

Currently, there are 3 main types of soundproofing: synthetic insulation and natural insulation. Zoom on the characteristics of these two types of products

Synthetic sound insulation

If we talk about soundproofing, synthetic products are the most widespread at present. Appreciated for their performance, but especially for their ease of installation which does not require the intervention of a professional, they are generally made of extruded polystyrene or polyurethane. These are recommended by acousticians and sound engineers worldwide.

Indeed, they are more adapted to ensure a uniform reflection of sound waves and correct echoes and reverberations. Thus, synthetic insulators are to be preferred if you have high requirements in terms of soundproofing. The disadvantage with this kind of product is that it is less affordable compared to natural ones.

Natural sound insulation

Natural soundproofing is also very common. However, these are usually devices designed for both thermal and sound insulation. They can also be called mixed insulation. Generally speaking, they are made of cellulose wadding, glass wool or cork board.

The installation of this type of insulation is less obvious and requires the intervention of a professional. This difficulty of installation as well as the lower soundproofing performance compared to synthetics largely explains the fact that natural insulators are less popular compared to synthetics.

Soundproofing or mixed insulation?


Soundproofing is the solution to reduce noise in a room. Made of sound-absorbing materials and designed to reflect sound more effectively, this type of product is intended solely for soundproofing and acoustic insulation. Also, it has very little effect on the thermal environment, unlike mixed insulation.

Mixed insulation

Mixed insulators are in fact thermal insulators that also bring their touch in sound insulation. Cork plates, glass wool or cellulose wadding play this double role. Thus, they are products designed to provide thermal and sound insulation at the same time. However, their performance in terms of sound insulation is largely inferior to clean soundproofing materials.


If you're looking for a way to soundproof a room, it's best to choose clean soundproofing. This is the best solution if you are building a movie theatre or a recording studio. On the other hand, if you want to kill two birds with one stone and ensure perfect thermal and sound insulation at the same time, opt for a mixed insulation. The best option is to install both types of products for optimal thermal and acoustic comfort.

Why buy soundproofing?

For acoustic comfort

Soundproofing reduces the impact of external noise on your acoustic comfort. It also reduces impact noise, in case you drop a large object. If you like good music or good sounds, you will appreciate the effects of these products thanks to a better circulation of sound waves.

To increase the value of your home

A home with soundproofing will be worth more than a standard home. Indeed, the calm and serenity induced by less exposure to outside noise is now a luxury. Therefore, by offering a well insulated home or building, you can increase the price or rent.

So that you don't hear what's going on at home

If you like to sing at the top of your lungs, play a musical instrument or talk loudly, it can annoy the neighbors. With a good soundproofing system, however, you can make sure that outsiders can't hear what's going on or even know what you're doing.

So you don't hear what's going on outside

Your neighborhood is a little too noisy for your taste when you need to concentrate on your daily activities, invest in a high-performance sound insulator. With this device, outside noise will no longer bother you when you are relaxing, working or talking on the phone with your loved ones.

To be able to make videos without background noise

If you like to make videos or if it is even your source of income, you need a soundproof environment to work in good conditions. With good quality soundproofing, you'll have a lot less work to do and you'll be able to make excellent quality videos.

The best brands of sound insulators

In our opinion, the best brands of sound insulators in 2022 are :

La maison du Liège

AP Acouspanel Building Acoustics is a company specialized in the design and marketing of accessories used in the world of sound treatment. The sound insulators of this brand are among the references in the field and are much appreciated by acoustics specialists.

KeyHelm is also among the references in the world of sound treatment and acoustic corrections. This brand is one of the world leaders in bass straps as well as other accessories including, of course, soundproofing.

Isover is part of the Saint-Gobain group, which has been marketing complete soundproofing solutions for over 75 years. This group specializes in the design of insulation made from recycled materials, notably glass wool.

Lafarge is a brand that needs no introduction. This construction giant has been around since 1848 and has made a name for itself in the marketing of ready-mix concrete. Having never stopped innovating, Lafarge now offers a wide range of products for sound insulation, including a mineral insulating foam with exceptional properties.

As its name suggests, this group markets cork-based products designed in the form of cork panels or rolls. Their products are designed for thermal and sound insulation at the same time.

What is the price for a sound insulator

The diagram below will help you to get an idea of the typical prices for each price range (entry-level, mid-range and high-end).

However, more expensive does not necessarily mean better.

We therefore advise you to always consult our ranking before deciding, rather than blindly relying on price ranges.

Have fun arranging the plates

When placing the insulation boards on the walls, you don't have to line them up. Arrange them in a diamond pattern or cut the sheets to create patterns. By doing this, you'll add a significant aesthetic touch and it will increase the absorption performance of the insulation.

Equip the doors too

If you have interior wood doors with little insulation, add a few insulation boards to strengthen their soundproofing. If you want to soundproof a recording studio and do not have the possibility of padding the doors, this technique represents a more than effective alternative.

Caulk the doors and windows

Fill the gaps at the level of the roller shutters, wooden windows or doors. By doing so, you will reinforce the soundproofing of a building. Use silicone instead, it is an affordable and easy to apply product.

Kill two birds with one stone

By opting for a mixed insulation, you will benefit, with a single product, from thermal and sound insulation. Choose this technique if you have the opportunity. As explained previously, this kind of method is less effective in terms of thermal insulation, unlike the use of a clean sound insulator.

Vary the colors

Opt for insulators of different colors to sublimate the aesthetic aspect of the room to insulate. Grey, black and garnet colored panels would lead to a more than interesting result and will stimulate your creativity.


How to define sound insulation?

Acoustic insulation means the action to reduce the flow of noise between two spaces. The goal is to ensure more privacy between rooms. Thanks, to an efficient insulation, people will have a better ability to concentrate in the reception area, which is an essential parameter to stimulate creativity and productivity.

What are the best materials to optimize the sound insulation of a building?

If you want to benefit from an optimal sound insulation, you must start from the structural works. Go for concrete and install a solid or hardscape slab to absorb sound. Then, insulate the walls with mineral insulation such as glass wool or rock wool, which are both thermal and sound insulators. Finally, opt, for a phonic insulation of good thickness to sublimate the general functioning.

What is the difference between impact noise and airborne noise?

In the framework of an impact noise, a place is in direct contact with the source of the sound. For example, the sound of footsteps above or the slamming of window sashes. Airborne noise refers to airborne sounds that reach our eardrums, such as the human voice, music or sounds from televisions. In both cases, good soundproofing can be the solution if these sounds are a problem.

Are there products that provide both thermal and sound insulation?

In fact, most thermal insulation is also soundproofing. Minerals such as rock wool and glass wool particularly fit this description. Cork insulation also performs both functions. However, it is necessary to remember that these mixed insulators are much less efficient than the clean sound insulators.
