ROCKWOOL® FLEXI® is a unique, flexi-edged insulation product, specifically developed using patented technology for a fast and easy, perfect friction fit between timber and metal frame systems.
ROCKWOOL FLEXI® is a multi-use, dual purpose thermal and acoustic insulation product with a unique flexible edge along one side. The patented flexible edge ensures a perfect fit is maintained between the product and its supporting framework for easy installation and optimum effectiveness.
FlexI® slabs ensure essential tight fitting for thermal and acoustic integrity between frames in walls, partitions, floors and roofs, without the need for cutting or waste. Made from renewable volcanic rock, they are extremely fire resistant and significantly reduce the carbon footprint of a building.
