Acoustic membrane for concrete slab floor systems

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.

• Typical application
• Usage Examples

• Concrete slabs
• Auto leveling
• Heated floors
• Floating floors

Heated concrete slab on SONOpro membrane for a better sound insulation against impact noise.
