PRODESO® SOUND STICK is an uncoupling and soundproofing membrane, with a thickness of 2.5 mm, composed of a high density polyethylene sheet to which two polypropylene nonwoven fabrics are heat-sealed. Due to its uncoupling properties, it is not necessary to respect any joint in the screed before the laying of tiles and natural stones. PRODESO SOUND STICK guarantees an acoustic wave reduction from foot traffic up to 17dB.
