100mm Rockwool Flexi Insulation Slab is a unique semi-rigid thermal and acoustic insulation product made from volcanic rock. It has a flexible edge, specifically developed using patented technology for a fast and easy, perfect friction fit between timber and metal frame systems. This flexi-edge ensures perfect fit between the slab and the surrounding frame, thus making sure that no gaps caused by contraction and expansion of the structure. This stays effective throughout the life span of the structure, thus minimizing the risk of cold bridging and also successfully blocks the passage of sound, improving the acoustics of the building. Rockwool Flexi Insulation Slabs are made from 97% recyclable and renewable material, They are environmentally friendly and they can lower the carbon footprint of the household.
