Rockwool Insulation Slabs (Density (Kg/M3): 90)

Our Rockwool Insulation Slabs are a high-performance, 3-in-1 solution, expertly engineered to provide exceptional thermal, acoustic, and fire protection for a wide array of general building applications. Made from natural, non-combustible stone wool, these slabs are designed to enhance energy efficiency, improve indoor comfort, and significantly increase the safety of any structure.

These semi-rigid slabs are easy to cut and install in walls, floors, ceilings, and roofs. Their dense, fibrous structure is not only excellent for retaining heat and reducing energy costs but also highly effective at absorbing sound waves, thus reducing noise pollution. A key feature is their outstanding fire resilience, with a Euroclass A1 non-combustible rating, meaning they can withstand temperatures up to 1000°C without melting or producing toxic smoke. Furthermore, the slabs are water-repellent and vapour permeable, resisting rot and mould while allowing the building to breathe. We offer 50mm thick slabs in a range of densities (40, 50, 70, 90, & 100 kg/m³) to meet specific performance requirements.
