CAVITY WALL INFILL

Rockwool granulated insulation is a stone based mineral fibre, it is mainly comprised of basalt rock and minerals, it creates very effective insulation with fire resistant and sound absorbing properties. It is used in loft and wall cavities by blowing it in through specialize hose fittings without any binders or glues. Rockwool granulate also repels water so it doesn’t allow water to penetrate through to your inner wall.
