Versatile insulation slabs for a wide range of building applications

25mm Rockwool RW3 Slabs work across general building settings, delivering acoustic, thermal, and fire protection for walls, ceilings, floors, and roofs. With thicknesses and densities ranging from 45 to 140 kg/m3, these slabs can feature black or white tissue facing or foil facing on one or both sides, subject to production compatibility.

Fire Performance

ROCKWOOL RW 25mm Slabs are non-combustible, achieving an A1 reaction to fire classification under EN13501-1 standards.

Acoustic Performance

Stone wool's non-directional fibre orientation and density trap sound waves and dampen vibrations effectively. This proves particularly valuable for reducing external noise when used in external walls.

Additionally, 25mm Rockwool insulation retains its original shape and thickness throughout the building's lifespan. This lasting structural integrity guarantees consistent acoustic insulation performance over many years.
