Acoustic insulation product comprising a backing layer
The invention relates to an acoustic insulation product (5) comprising a panel (1) made of porous material, based on foam or fibres, comprising a first face, referred to as back face (20), intended to face towards a wall, and a second face, referred to as front face (30), situated on the opposite side to the back face (20), and a layer, referred to as backing layer (2), which adheres to or is linked or coupled at least in part to the back face (20) of the panel (1) made of porous material, the backing layer (2) having an airflow resistance of between 5 kPa.s/m and 20 kPa.s/m, preferably between 7 kPa.s/m and 15 kPa.s/m. The acoustic insulation product according to the invention is able to improve both acoustic insulation and noise absorption.
