Specialist Acoustic Mineral Wool for Part E Building Regulations Compliance
Knauf Acoustic Mineral Wool (RS60) (60kg per m3) is high-density acoustic mineral wool that is used to treat the ‘open spaces’, or cavities, between flooring joists, stud-frame walls and battened ceilings. As an open-fibrous material, it helps to reduce sound energy by turning it into heat, helping to reduce cavity resonance. As a standalone product, it is only effective against very light background noise issues. We recommend Knauf Acoustic Mineral Wool to be used as part of a system when a cavity is created or existing.
Acoustic Mineral Wool will also help to prevent Flanking Transmission adjacent open cavities. Any acoustic system fitted without this material will not achieve its full acoustic performance and may fall short of expectations or essential acoustic regulations.
Acoustic Mineral Wool has a greater density than thermal wool, and this is evident in their slab appearance. The reduction as an acoustic insulation material comes as an absorptive rating NRC (Noise Reduction Coefficient) which differs for each thickness. This means that it is an absorptive material as opposed to a dense soundproofing product. You will find all acoustic systems that Acoustic Mineral Wool is featured in by selecting the ‘Systems’ tab above. Here you will see how vital it is!

FAQs
Installation Guide
Acoustic Mineral Wool is not listed as a toxic or hazardous material, but when installing it does release small dust particles, so we recommend the use of gloves, eye protection and protective mask.
Measure the depth of the cavity first, or if you know the stud depth you are using, make sure that you choose a depth of Acoustic Mineral Wool that allows for a 10mm air gap on either side.
The reason you leave this air gap is to avoid compressing the fibrous properties between the two partitions you are soundproofing, for example, do not use a 100mm depth in a 50mm gap.
Acoustic Mineral Wool is easy to cut with large scissors, or we found a bread knife to be a great tool here.
Cut the slab a little larger than the stud or joist gap to friction hold, or use a form of wiring to hold it in place.
