Rockwool Acoustic Mineral Wool RW5 50mm 100kg/m³

Rockwool Acoustic Mineral Wool (RW5) (100kg per m3) is our highest density acoustic mineral wool that is used to treat cavities, between flooring joists, stud-frame walls and battened ceilings.

Acoustic Mineral Wool works by lessening sound energy helping to decrease the remaining noise ‘bouncing’ around inside the cavity and amplifying (like a drum). We recommend using Rockwool RW5 as part of a system or to reduce Flanking transmission.

Bass Frequency

Bass frequency absorption

Bass frequencies are difficult to treat with soundproofing. Rockwool RW5 has a good absorption coefficient at bass frequencies, making it an essential upgrade to most soundproofing systems.

Mineral wool RW5 studio soundproofing

Studio Soundproofing

As a denser product Rockwool RW5 lends itself to higher-end acoustic systems like soundproofing a studio or soundproofing a cinema. It can also be used to increase the performance of everyday soundproofing systems.

How to cut mineral wool

Easy to cut

For clean cuts, keep your mineral wool in its wrapping and make two even cuts with a serrated knife or saw. this will leave you with three sets of 400mm slabs. Don’t forget to wear PPE!

Installing Acoustic Mineral Wool

Easy to install

Cut your slabs slightly larger than the application area and simply pressure fit them to hold them in place.

Fire rated 01

A1 fire rated

Rockwool RW5 has a Euroclass A1 fire rating, meaning it is completely non-combustible. This is an excellent safety feature and is often required for building regulations.

Thermal insulation

Thermal insulation

Alongside its enhanced acoustic capability acoustic mineral wool carries the same thermal insulation properties as its standard counterpart. Rockwool RW5 has a thermal conductivity of 34 W/mK.

  1. Although acoustic insulation used here is not toxic or hazardous, when installing mineral wool does release small dust particles, so do use gloves, goggles and a face mask.
  2. 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.
  3. 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.
  4. Acoustic Mineral Wool is easy to cut with large scissors, or we found a bread knife to be a great tool here.
  5. 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.

Soundproof plasterboard works best as part of a system like our MuteClip systems, or when combined with other materials.

60kg is the density of the product when measured in cubic meters and not the weight of a single slab or bale of acoustic mineral wool – it is a reasonably lightweight sound insulation product that is easy to cut and easy to lay, use gloves and eye protection and keep the area ventilated during and after installation.
