  • 140mm Rockwool Flexi Acoustic Sound Insulation Slab (2.88m2/Pack)

    Rockwool 140mm Rockwool Flexi Acoustic Sound Insulation Slab (2.88m2/Pack)

    140mm Rockwool Flexi Insulation Slabs are a multi-purpose insulation solution for use in metal and timber framing systems. Like Rockwool RWA45, these dense slabs offer effective thermal and acoustic performance. They also give excellent fire protection, with a classification of A1 non-combustible. What sets these 140mm Rockwool Flexi Slabs apart from other Rockwool slabs is that they have a special flexible edge, which allows them to be perfectly friction fitted within the supporting framework. They are suitable for installation between wall frames, roofs, floors and partitions. 140mm Flexi Slabs are made from renewable volcanic rock that is burned at an extremely high temperature. This makes them environmentally friendly and effective at reducing the carbon footprint of the building.
