Abstract
An acoustic insulation product includes a panel made of porous material, based on foam or fibres, including a first face, referred to as back face, intended to face towards a wall, and a second face, referred to as front face, situated on the opposite side to the back face, and a layer, referred to as backing layer, which adheres to or is linked or coupled at least in part to the back face of the panel made of porous material, the backing layer having an airflow resistance of between 5 kPa·s/m and 20 kPa·s/m.
Claims20
An acoustic insulation product, comprising:
- a panel made of porous material comprising a first face forming a back face, intended to face towards a wall surface and a second face forming a front face, situated opposite to the back face,
- a layer forming a backing layer, which adheres to or is linked or coupled at least in part to the back face of the panel made of porous material, the backing layer having an airflow resistance of between 5 kPa·s/m and 20 kPa·s/m,
- wherein the panel made of porous material has an airflow resistivity of between 30 kPa·s/m2 and 120 kPa·s/m2.
A method comprising:
- forming an acoustic ceiling tile with an acoustic insulation product on a frame suspended from a ceiling with a plenum between the acoustic insulation product and the ceiling,
- wherein the acoustic insulation product includes a panel made of porous material comprising a first face forming a back face, intended to face towards a wall surface and a second face forming a front face, situated opposite to the back face, and a layer forming a backing layer, which adheres to or is linked or coupled at least in part to the back face of the panel made of porous material, the backing layer having an airflow resistance of between 5 kPa·s/m and 20 kPa·s/m, and wherein the backing layer is oriented toward the ceiling, and
- wherein the panel made of porous material has an airflow resistivity of between 30 kPa·s/m2 and 120 kPa·s/m2.
