Versatile insulation slabs for a wide range of building applications

75mm Rockwool RW3 Slabs provide flexible solutions across general building projects, delivering acoustic, thermal, and fire protection for walls, ceilings, floors, and roofs. With densities spanning 45 to 140 kg/m3 and multiple thickness options, these slabs can be customised with black or white tissue facing or foil facing on one or both sides, subject to production compatibility.

Fire Performance

ROCKWOOL RW 75mm Slabs exhibit non-combustible characteristics, attaining a reaction to fire classification of A1, as outlined in EN13501-1 standards.

Acoustic Performance

The random fibre orientation and density inherent in stone wool effectively trap sound waves and dampen vibrations. This property proves highly effective in significantly reducing external noise sources when employed in external walls.

Additionally, 75mm Rockwool insulation maintains its original shape and thickness throughout the building's lifespan. This enduring structural integrity ensures consistent acoustic insulation performance over many decades.
