Impact sound insulation



Vibration damping


Impact noise is a type of structure-borne noise that may be caused, for example, by a person walking across a floor or down a stairs.

If high-quality impact sound insulation such as VIBRAX-FOAM is not provided, the resulting vibrations can cause disturbances in neighbouring or connecting areas.

Impact sound insulation and impact noise reduction are thus an important part of the construction industry.

Effective impact sound insulation can be achieved by the use of high-quality impact noise insulation products from the VIBRAX range, such as VIBRAX-FOAM.

VIBRAX-FOAM is a profiled mat product that is manufactured from granulated PU foam material, for impact noise insulation and structure-borne noise isolation under floating sub-floors or load-distributing slabs.

In contrast to impact noise insulation directly beneath the floor surfacing, this enables disturbing impact noise to be already combatted between structural slab and sub-floor.
VIBRAX-FOAM is building authority-approved in Switzerland, Germany and other countries, and offers very high compression strength and excellent noise protection, even at low thicknesses.

It has particularly proven its worth in the construction of mixed-purpose buildings and hotels, as structure-borne noise isolation bearings for machinery, as bearing supports for load distributing slabs and sub-floors, and on timber structures.


VIBRAX-FOAM – Impact/footfall noise reduction beneath floating subfloors: up to 35 dB
