Rockwool RWA45 Slab 100mm (2.88m2)
Rockwool RWA45 is a high-performance stone wool insulation slab designed to provide excellent acoustic, thermal and fire performance within a wide range of construction applications. Manufactured from non-combustible stone wool, RWA45 is widely used within drylining partitions, Steel Framing Systems (SFS), MF ceiling systems, floor constructions and internal wall applications where sound reduction and fire resistance are important requirements.
The rigid yet flexible slabs are easy to install between metal studs, timber studs and framing systems, helping to reduce airborne sound transmission while also improving thermal efficiency.
