Impact noise reduction material
Impactafoam is designed to form a resilient layer, reducing impact noise transmission in concrete and timber floors. Impactafoam is an inert, cross-linked, closed-cell polyethylene foam, therefore providing a vapour barrier with good compression strength.
- Reduces impact noise
- Only 5mm thick
- Offers high compression strength
- Easy to lay and cut
- Good vapour barrier
- Good chemical resistance
- Does not deteriorate or mildew
In a concrete construction, Impactafoam is laid as a embrane between a structural concrete floor of mass 300Kg/m² and the finishing screed. For a raft floor construction, Impactafoam batten strips are applied to the underside of the timber battens. In conventional timber construction, self-adhesive batten strips are easily applied to the top of the floor joists. This forms a resilient layer between the joists and the boarding, reducing impact noise.
