70mm Rockwool Flexi Acoustic Sound Insulation Slab (5.76m2/Pack)

Stone wool insulation slab, measuring 70mm in thickness and cut to 1200 × 600mm, for use in partitions and floors.With a patented flexible edge, it securely friction fits within framed constructions, reducing the need for excessive cutting and limiting waste on site.In a single solution, it provides reliable acoustic absorption, effective thermal insulation with a conductivity of 0.038 W/mK, and the highest level of fire safety (A1 non-combustible).Its semi-rigid form allows straightforward handling and installation, while maintaining a close fit to minimise gaps that could compromise performance.At 70mm thick, the slab provides a balanced profile that enhances both acoustic and thermal performance while keeping overall build-up relatively slim.This intermediate depth makes it a versatile option for partitions and floors where improved comfort, energy efficiency, and fire protection are needed without significantly increasing wall or floor thickness.
