ROCKWOOL Flexi Slab Acoustic Insulation 1200mm X 400mm X 140mm- 1.92m2 Pack

For superior thermal insulation, acoustic performance and fire resistance in all framed areas of the building, this ROCKWOOL Flexi Slab is an exceptional insulation product. It comprises a semi-rigid slab, featuring a unique flexible edge along one side. Flexi-edges provide an efficient and swift friction fit for timber and metal frame systems, using exclusive patented technology.

While ensuring a secure and snug fit for thermal and acoustic integrity between frames in walls, partitions, floors and roofs, there is zero wastage and no need for cutting. These slabs are made from a renewable volcanic rock material, which is highly resistant to fire and significantly lowers the building’s carbon footprint. Whether un-faced or aluminium foil or glass fleece faced (one or both surfaces), ROCKWOOL RW slab products attain an A1 classification to BS EN 13501-1 and meet the requirements of non-combustible materials/products defined in all UK and Ireland Building Regulations.

The ROCKWOOL Flexi Slab is a versatile insulation product that serves a dual purpose for thermal and acoustic insulation. Its distinct flexible edge on one side ensures a seamless fit between the product and its supporting framework, resulting in optimal efficiency.

ROCKWOOL stone wool solutions effectively mitigate noise through two approaches: obstructing sound transmission via the structure, or absorbing sound at the surface. The unique fibre structure of ROCKWOOL RW slabs makes them optimal for sound absorption, delivering characteristically high coefficients across a broad frequency spectrum.
