Versatile insulation slabs for a wide range of building applications

50mm Rockwool RW3 Slabs provide flexible solutions for general building work, delivering acoustic, thermal, and fire protection across walls, ceilings, floors, and roofs. Available in multiple thicknesses and densities ranging 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 compatibility.

Fire Performance

ROCKWOOL RW 50mm Slabs demonstrate non-combustible properties, achieving an A1 reaction to fire classification as per 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, 50mm Rockwool insulation maintains its form and thickness over the building's entire service life. This consistent structural stability guarantees reliable acoustic insulation performance year after year.

Extras

1. Engineered to provide multiple thermal and acoustic benefits.
2. Ideal for a broad spectrum of general building applications.
3. Non-combustible with Euroclass A1 rating per EN 13501-1 standards.
4. Supplied in various thicknesses and densities to suit different project specifications.
