Fire Performance

ROCKWOOL RWA45 50mm Slabs are non-combustible, achieving an A1 reaction to fire classification under EN13501-1 standards.

Acoustic Performance

Stone wool's non-directional fibre structure and density trap sound waves and dampen vibrations effectively. This makes it particularly useful for reducing external noise when fitted in external walls.
