75mm Rockwool RWA45 Acoustic Sound Insulation Slab (4.32m2/Pack)

Stone wool insulation slab, measuring 75mm 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 75mm thick, the slab offers a versatile mid-range option within the RWA45 range. It is commonly specified in residential and commercial partitions where higher acoustic performance is needed than thinner slabs can deliver, but without the full depth of 100mm.
