Rockwool Sound Isolation insulation RWA45 100mm 45kg/m³ – 12 Bales
Rockwool sound isolation insulation (RWA45) (45kg per m3) is high-density acoustic mineral wool that is used to treat cavities, between flooring joists, stud-frame walls and battened ceilings.
sound isolation insulation 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 RW3 as part of a system or to reduce Flanking transmission.

Bass frequency absorption
Bass frequencies are difficult to treat with soundproofing. Rockwool RWA45 has a good absorption coefficient at bass frequencies, making it an essential upgrade to most soundproofing systems.
Multi-use application
Whether you are treating your wall, floor or ceiling Rockwool RWA45 is ideal to fill joists, stud frames, battens and acoustic cradles.
Easy to install
Cut your slabs slightly larger than the application area and simply pressure fit them to hold them in place.
A1 fire rated
Rockwool RWA45 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
Alongside its enhanced acoustic capability acoustic mineral wool carries the same thermal insulation properties as its standard counterpart. Rockwool RWA45 has a thermal conductivity of 0.035 W/mK
