Soundproofing carpet for acoustic insulation against trampling noise.
Drying not needed.
1,20 x 60 m roll
Soundproof polyester nonwoven coated with a synthetic film for reducing footstep noise (expecially floating floorings). Placing between the finishing layer of the systems and the oversite concrete on which the flooring is laid creates a “mass-spring-mass” structure that blocks vibrations by making the floor less rigid.
