The roar of engines and the incessant horns, the endless evenings of the student roommate in the apartment next door and the morning gymnastics sessions of the sportsman above… You love your cozy little nest, but can't stand it anymore. hear noises coming from the street or from your next door neighbors.
Like nearly 40% of French people, you consider these nuisances to be a stressor and want to protect yourself from them.
The only solutions to remedy your problem: move to the depths of the countryside or carry out sound insulation work in order to bring calm and serenity to your home.
Here are different techniques
High-performance insulating materials
In order to create a protective layer that can dampen sounds and block their propagation, you have a choice of various materials.
Made from a natural material resulting from volcanic activity, rock wool is an effective mineral insulator to reduce impact noise and can also act as thermal insulation.
Glass wool is more suitable for acoustic correction, in order to absorb sounds in low thicknesses.
You can therefore use it to double a floating slab on the ground but also, why not, some custom furniture.
Lighter, polyurethane composite foam is a little less sound-insulating than mineral wool, but it can be more easily used in certain delicate spaces.
Likewise, blown cellulose fiber granules are popular for their ease of installation.
Finally, to insulate your floors, you can opt for cork, not to mention coverings that muffle sounds such as thick carpet or linoleum.
Do not hesitate to mix several materials, the density variations being recommended to absorb the various sound frequencies.
Each element has its own insulation technique
Depending on the wall you want to insulate and the noise involved, you can opt for various insulation techniques.
For your walls and partitions, the two main solutions are ready-to-use sandwich panels and insulation on metal frames and plasterboards.
In order to increase the sound insulation of your floors, the installation of a floating slab separated from the walls or of a sound-absorbing coating (carpet, floating parquet) is also beneficial.
However, it requires sufficient ceiling height and it will be almost inevitable to plan your doors.
Finally, to mitigate the nuisance from the floor above, a false ceiling on a frame with the incorporation of an insulation - for example the installation of a layer of mineral wool between the slab and the Placo® plates - can change you life.
Windows, a point not to be overlooked
If they are often the first responsible for heat loss in collective dwellings, windows can also be a source of acoustic discomfort.
It is therefore imperative to have double or even triple glazing installed in order to benefit from maximum tranquility, especially in an urban environment.
Note that there are also laminated glasses on the market with a special transparent film silencing maximum sound reduction that helps reduce two to four times the volume of noise pollution.
Shutters, the secret asset
Indispensable for obscuring light and securing our homes, shutters increase thermal and sound comfort.
Indeed, the air chamber located between the window and the shutter insulates you from outside temperatures, but it also dampens sounds, which will therefore be less perceptible in one direction or the other.
Roller shutters are often the most effective for gaining acoustic privacy.
