75mm Rockwool RW5 Acoustic Sound Insulation Slab (2.16m2/Pack)

Stone wool insulation slab, 75mm thick and cut to 1200 × 600mm, developed for demanding acoustic and fire-rated constructions.With a density of 100 kg/m³, the slab offers a robust balance of rigidity and sound absorption. The added mass helps to block airborne noise transfer, while the dense fibre structure absorbs sound within the cavity, improving acoustic comfort across partitions, floors, and ceilings.This higher density also gives the slab excellent dimensional stability, supporting structural integrity and ensuring it holds its shape once installed. Its semi-rigid form allows for a friction fit that minimises air gaps and maintains consistent performance.Classified as non-combustible, the slab provides reliable fire resistance, contributing to enhanced safety within the building fabric.At 75mm thick, it delivers strong levels of airborne sound reduction and fire performance, making it suitable for a wide range of acoustic and fire-rated applications where both noise control and safety are priorities.
