Download Specification

ROCKWOOL Acoustic Membrane is a flexible, high-density polymer mass layer. The product, when combined with ROCKWOOL insulation products, offers both high performing and economic acoustic solutions for flat roofing and built-up metal roofing systems. An ideal acoustic solution for buildings requiring high levels of acoustic performance.

Applications

ROCKWOOL Acoustic Membrane is designed to enhance the acoustic performance of flat roof constructions in conjunction with Hardrock Multi-Fix insulation.

Performance

Several airborne and rain noise acoustic tests have been carried out on various roof constructions incorporating ROCKWOOL Acoustic Membrane and Hardrock MultiFix. The results from these test programmes have allowed for accurate assessment of intermediate performances. For more information please contact Technical Solutions on 01656 868 490.

Weather protection

All products are wrapped in polythene for short-term protection, if stored outside. For longer-term protection, the product should be stored in dry premises, protected against weathering, and must not be exposed to temperatures exceeding 35°C.

Installation

ROCKWOOL Acoustic Membrane should be laid directly onto the metal decking, across the line of the profiles. The metal decking must be clean and dry. Align the membrane and extend the roll over the metal decking progressively. Please note that it is not necessary to remove the protective plastic film.

All membrane joints should be overlapped by a minimum of 50mm as small openings can reduce the level of acoustic insulation achieved. Where required, ROCKWOOL Acoustic Membrane is easily cut or shaped with a sharp knife.

Health & Safety

The safety of ROCKWOOL stone wool is confirmed by current UK and Republic of Ireland health & safety regulations and EU directive 97/69/EC:ROCKWOOL fibres are not classified as a possible human carcinogen.

A Material Safety Data Sheet is available and can be downloaded from www.rockwool.co.uk to assist in the preparation of risk assessments, as required by the Control of Substances Hazardous to Health Regulations (COSHH).
