Impactafoam - sound insulation

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. In a concrete construction, Impactafoam is laid as a membrane 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 a 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.

The Benefits

• Impactafoam Reduces impact noise
• Impactafoam is only 5mm thick
• Impactafoam offers high compression strength
• Impactafoam is easy to lay and cut
• Good vapour barrier
• Good chemical resistance
• Impactafoam does not deteriorate or mildew

Impactafoam is made up of thousands of tiny cross-linked cells. Therefore even if some cells become punctured Impactafoam continues to perform, with good compression strength and low thickness loss.
