Sound insulation material for floors - Impact noise

FONOTEC Plus is an impact subflooring obtained by bonding a viscoelastic polymer soundproofing membrane with a layer of polyester fibre with high noise absorption capacity. The exposed side is finished by a heat-reflective film made of aluminized polyethylene which not only meet the practical need of waterproofing the surface, but also facilitates the reflection by radiation of heat towards the heated environments. The use of this finishing result is greater in conjunction with the radiating panel for under floor heating. The product is manufactured in rolls and is equipped with longitudinally overlapping selvage to facilitate the laying of the flooring system. These features make it possible to lay the soundproofing flooring while limiting the risk of any acoustic bridges.
