50mm Rockwool RWA45 Acoustic Sound Insulation Slab (6.48m2/Pack)

Stone wool insulation slab, measuring 50mm in thickness, designed for use in internal partitions, floors, and roof applications.Manufactured from high-density stone wool, the slab combines excellent acoustic absorption with reliable thermal insulation and inherent fire resistance. Its rigid composition allows a close friction fit between studs or joists, preventing gaps that could compromise performance.Non-combustible and classified as Euroclass A1, the slab contributes to improved fire safety within the building fabric. Its fibre structure also provides effective sound reduction, limiting noise transfer between rooms and floors.At 50mm thick, this slab is suited to lightweight partitions and areas where space is limited but effective sound control and fire resistance are still required. It is often used in domestic walls, ceilings, and floors where moderate acoustic performance is sufficient without increasing wall or floor build-up depth.
