Prodeso® Sound System is an uncoupling and soundproofing membrane to be applied under tile, which reduces 17 Db of the acoustic wave produced by footsteps. Thanks to its uncoupling function, it is possible to renovate houses without removing the old flooring; it is enough to glue the membrane on the old flooring and directly on it, the new one, without being obliged to respect any expansion joints. The system, designed by Progress Profiles, offers many advantages, which guarantee maximum installation flexibility and protection of the flooring over time.
