Product Details

Acoustic Floor Roll is a resilient glass mineral wool roll faced on one side with a kraft paper/polythene laminate. Its facing has a 75mm overlap along one edge to lap the edge of the adjoining roll.

Acoustic Floor Roll 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.

The mineral wool of Acoustic Floor Roll is a non-combustible, inorganic glass wool, defined as mineral wool in BS 3533: 1981 and is manufactured in accordance with BSI Quality Assurance Standard BS EN ISO 9001: 2000.

The mineral wool of Acoustic Floor Roll is odourless, rot proof, nonhygroscopic, does not sustain vermin and will not encourage the growth of fungi, mould or bacteria.

The base glass mineral wool of Acoustic Floor Roll is classified as non-combustible to BS 476: Part 4: 1970 (1984).

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.

***Handling and Storage*

Acoustic Floor Roll is easy to handle and install, being lightweight and easily cut to size.

It is supplied enclosed in polythene which is designed for short term protection only. For longer term protection on site, the product should either be stored indoors, or under cover and off the ground.

Installation instructions are on every pack. Acoustic Floor Roll should not be left permanently exposed to the elements.
