BENEFITS

Acoustic performance

Rock wool stone wool mieral wool basalt 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 slabs make them ideal for use as a sound absorber, with characteristically high coefficients over a wide frequency range.

Fire resistance

All Rock wool stone wool mieral wool basalt wool 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 & maintenance

Rock wool stone wool mieral wool basalt wool productsl are light and easy to cut to any shape with a sharp knife.

Once installed the Rockwool slabs need no maintenance.

Standards

Reaction to fire: A1 classification to BS EN 13501-1
