Whether it is to isolate impact noises or airborne noise (discussions, etc.), there are several solutions to isolate your floor acoustically.
The importance of good sound insulation
Footsteps, furniture or impacts (objects falling on the ground) can be transmitted to the lower floor through the ceiling or the vertical walls (walls). Airborne sounds, ie voices, music or television can also be heard in other rooms of the building, especially the rooms on the lower floor. It is therefore important for everyone's comfort to insulate the floor.
Sound insulation thanks to the floor covering
A soft coating such as carpet absorbs impacts and reduces noise. Natural fiber or PVC flooring also helps reduce noise. However, the flooring is not always enough to provide good insulation.

How to isolate your soil?
There are two solutions to isolate a soil:
- Insulate the soil from above: it is a question of putting an insulating sub-layer before the installation of the floor covering. You can find insulation in the form of panels or rolls, and in different materials. Insulating from above is easy enough.
- Insulate the soil from below: it is to isolate the ceiling of the lower floor, by fixing insulating panels, for example. This method of insulation is preferred for the ground of your ground floor, if you have a crawl space or a cellar.
Which sound isolator to choose?
The mineral wool (rock, glass) or Natural (wood, hemp, cellulose, cork) are suitable for sound insulation of a floor. These materials are also suitable for thermal insulation, except cork.
On the other hand, do not choose polystyrene for your sound insulation. It performs well for the thermal insulation of a floor, but does not offer good performance for sound insulation.
A good thermal insulation is not necessarily a good sound insulation. Ask a professional to accompany you.
