Impactabloc ™ vibration damping underlay Impactabloc ™ vibration damping underlay mat Impactabloc ™ vibration damping underlay mat


Impactabloc ™ is a superb acoustic floor system designed to improve both the impact and airborne noise transfer through floors. The laminated composition provides maximum performance for minimum thickness and combines excellent sound insulation with all the qualities of a good carpet underlay. It is quick and easy to install and is easily cut and shaped. Overall thickness is just 12mm so it minimises the increase in floor level.

Acoustic performance

This product comprises an 8mm layer of Impactabloc ™ chipfoam bonded to a top layer of 5kg mineral loaded barrier mat and a base layer of 3Kg mineral loaded barrier mat. The base layer of barrier mat seals and damps the sound coming through the floor, the isolated top layer of barrier mat blocks the sound both ways and the chipfoam core dramatically reduces impact noise transfer.
