MSL SonoPro

SONOpro is a high performance underlay membrane specifically designed to absorb impact noise under concrete screed and self-levelling floor systems (e.g. 1.5″ screed in wooden frame constructions). Composed of an impact noise absorbing acoustic felt combined with a high-grade polyethylene film, SONOpro prevents rapid water evaporation and allows optimum curing time for concrete. SONOpro permits decoupling of the floor from the structure to create a continuous seal.
