Impactafoam is designed to form a resilient layer reducing impact noise transmission in concrete and timber floors. It is an inert crosslinked closed-cell polyethylene foam, therefore providing a vapour barrier with good compression strength. In concrete construction, it is laid as a membrane between a structural concrete floor of mass 300Kg/m2 and the finishing screed. For raft floor construction 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.
