Stone wool Petralana PETRAFAS 250mm

Facade wool for thermal, acoustic and fire insulation of external walls and ceilings and ceilings above garages and car parks. In combination with adhesive mortar, a reinforcing layer and thin-coat plaster, façade wool forms an ETICS insulation system.
Unlike polystyrene, wool is vapour-permeable and does not impede the diffusion of water vapour through the envelope, accelerating the drying of walls from process moisture and preventing long-term dampness of walls, which is conducive to the occurrence of mould and fungi.
