Acoustic insulation
The type of acoustic insulation should be chosen carefully. Indeed, your neighbor below, if you do not have enough isolation, could be bothered by noise impacts on the floor.
The performance of insulation and the layer isloante (DLw) are expressed in dB, the thickness of the wooden floor played a leading role in the soundproofing, if the wooden floor is thin better will be the results.
It is important to note that the quality of the building, the thickness of the slab have a significant impact on the quality of insulation, ideally should be a measure in situ in order to know the L'nT, wla NRA (New Rules acoustic) imposes 58dB5 (A) in the local reception, plus The nT, w is little better performance.
To avoid bridges phonic the baseboard must be désolidarisée from the floor.
It is noteworthy that the acoustic insulation compressibles see their performance decrease when the floor is appointed by heavy furniture, it can result in unsightly deformity. Floor on lambourdes floating obtain excellent results.
If the building where you plan to install a wooden floor is deemed sound we ask you to report at the request. Before placing an order, we recommend that you check with your architect, where applicable, a control office, that the technology that we provide will give you sufficient reduction noise .

The view point of Emois et Bois
The experience has led us to conclude that wooden floor glued on a insulating layer gives you in most cases a satisfactory soundproofing without causing a noise not uncomfortable at home, choosing a thin parquet get better soundproofing.
These values can vary depending on the thickness and the type of wood.
