Product Description Rockwool Sound Insulation Slab is made from stone wool. The non-directional fibre orientation and density means that sound waves are trapped, and vibrations dampened. The acoustic slab also repels water and is vapour permeable, resisting rot and mould. In addition to its acoustic insulation properties, Rockwool Sound Insulation Slab has achieved a Euroclass A1 fire rating and is capable of withstanding temperatures in excess of 1000°C. The insulation slabs are easy to cut and fit around cables, pipes, sockets and services. The patented ‘FLEXI’ edge supports friction fitting without leaving gaps or cracks which could significantly reduce performance.
