The Rockwool Flexi Slab (400mm) is a versatile, high-performance stone wool insulation designed to provide exceptional acoustic, thermal, and fire protection across a wide range of applications. Featuring a unique flexible edge for a snug friction-fit, it’s perfect for pitched roofs, partition walls, intermediate floors, and framed constructions in both residential and commercial buildings. Combining durability, ease of installation, and sustainable materials, it’s a trusted choice for long-lasting insulation performance.
Benefits
- Effectively absorbs sound to reduce noise transmission between rooms, floors, and walls
- Low thermal conductivity of 0.038 W/m·K (50–120 mm) and 0.035 W/m·K (140 mm +), helping to improve energy efficiency and indoor comfort
- Rated Euroclass A1 non-combustible, offering the highest level of fire safety
- Unique flexible edge ensures a tight friction-fit and compensates for minor framework movement or timber shrinkage, reducing gaps and heat loss
- Water repellent and rot resistant, preventing moisture build-up, damp, and decay for long-lasting performance
- Highly durable, maintaining its structure and insulation performance throughout the building’s lifetime
- Semi-rigid, lightweight slabs that are easy to handle, cut, and install
- Made from natural volcanic rock and recycled materials, contributing to an environmentally responsible build
- Suitable for residential, commercial, and industrial projects, including schools, hospitals, and offices
Good to Know
- Suitable for use in pitched roofs, partition walls, intermediate floors, separating floors, and framed constructions
- Flexible edge allows a tight friction-fit between timber or metal studs, ensuring consistent performance even if the framework moves or settles
- Use a utility or serrated knife to cut the slabs cleanly; wear gloves and goggles to avoid irritation
- Please store under cover and clear of the ground. Avoid prolonged exposure to the elements, especially direct sunlight and rain
- Specialist PPE is not required, although if you are cutting the insulation in an unventilated area, it is recommended to use a suitable dust mask
