Versatile insulation slabs for a wide range of building applications

90mm Rockwool RW3 Slabs work well in general building projects, delivering acoustic, thermal, and fire protection for walls, ceilings, floors, and roofs. Available in various thicknesses and densities from 45 to 140 kg/m3, these slabs can be customised with black or white tissue facing or foil facing on one or both sides, subject to production capability.

Fire Performance

ROCKWOOL RW 90mm Slabs are non-combustible, achieving an A1 reaction to fire classification under EN13501-1 standards.

Acoustic Performance

The random fibre orientation and density of stone wool effectively trap sound waves and dampen vibrations. This makes it highly effective at reducing external noise when used in external walls.

Additionally, 90mm Rockwool insulation retains its original shape and thickness throughout your building's life. This consistent structural integrity ensures reliable acoustic insulation performance year after year.
