Acoustic performance
Rockwool stone wool products work in two distinct ways to reduce noise, either by impeding the transmission of sound through an element of the structure or by absorption of sound at the surface.

The structure of the fibres in Rockwool RW slabs make them ideal for use as a sound absorber, with characteristically high coefficients over a wide frequency range.

Fire resistance
All Rockwool RW slab products, either un-faced or with an aluminium foil or glass fleece on one or both surfaces, achieve an A1 classification in accordance with BS EN 13501-1 and therefore comply with the requirements of non-combustible materials/products, as defined in all UK and Ireland Building Regulations.

Handling & storage
Rockwool RW slabs are light and easy to cut to any shape with a sharp knife.

Once installed the Rockwool RW slabs need no maintenance.

1 review for 50mm Rockwool RWA45 Acoustic Insulation Slab 1200 x 600mm 6.48m2 Pack

  1. Rich (verified owner)

    Does what its supposed to

    The semi rigid nature makes it very easy to cut/form into the tight spaces we were trying to squeeze insulation into.

    Sound deadening is much much better than without it.
