Versatile insulation slabs for a wide range of building applications

25mm Rockwool RW5 Slabs suit numerous general building applications, delivering acoustic, thermal, and fire protection for walls, ceilings, floors, and roofs. Available in multiple thicknesses and densities ranging from 45 to 140 kg/m3, these slabs can be upgraded with black or white tissue facing or foil facing on one or both sides, depending on production compatibility.

Fire Performance

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

Acoustic Performance

The random fibre structure 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, 25mm Rockwool insulation retains its original shape and thickness throughout the building's service life. This consistent structural stability guarantees reliable acoustic insulation performance year after year.
