Product Details

This product is used for improving the impact sound resistance of separating floors, specifically Type 2 separating floors in Approved Document E.

The kraft paper/polythene laminate should face uppermost when Acoustic Floor Roll forms a resilient layer below a screed.

Acoustic Floor Roll meets the specification for a resilient layer in a Type 2 floor construction as recommended in Approved Document E 2003 of the Building Regulations, for separating floors.

Used with the appropriate ceiling and floor surface treatments and a structural deck of the appropriate mass, this system has the potential to provide the impact and airbourne sound insulation requirements of Part E.

Post completion testing is still normally required to demonstrate compliance.The acoustic performance depends on the mass of the concrete, which needs to be at least 300 kg/m².
