Stone Mineral Wool Insulation

Rock wool, Earth wool, and Stone wool slabsStone-wool slabs provide fire protection, as well as high thermal and acoustic performance and is ideal for light-weight framed buildings.

Stone wool is is processed molten volcanic rock into which air or steam is introduced. The product is then spun on high speed spinning wheels. The result is a mass of fine, intertwined fibres that are compressed and bonded using either petroleum based chemicals.

Knauf Insulation now use their Ecose™ technology to bind their products with 'rapidly renewable organic materials', rather than potentially hazardous petrochemical materials ... obviating the need for phenol, formaldehyde, and/or acrylics in their more easy to handle range of products

Stone wool slabs offer a balanced combination of thermal and acoustic insulation

While PIR and Phenolic boards offer better thermal properties than stonewool slabs of a similar thickness, rock wool products provide superior acoustic solutions. Stone wool offers the further benefit of being significantly less likely to introduce condensation into elements of a construction, than their aluminium faced counterparts.
