120mm Rockwool Steel Frame Slab 3.6m²

The Rockwool Steel Frame Slab is a robust stone wool insulation designed specifically for modern light-gauge steel constructions. Engineered to deliver dependable thermal, acoustic, and fire protection, it provides a reliable solution for external walls, infill panels, and cladding systems. Its semi-rigid structure offers a secure friction fit, ensuring consistent performance across both residential and commercial steel-frame projects.

Benefits

• Helps reduce heat loss thanks to its low thermal conductivity, improving whole-building energy efficiency
• Achieves the highest Euroclass A1 non-combustible fire rating for exceptional safety
• Open-fibre composition absorbs sound effectively, improving interior comfort and reducing external noise impact
• Water-repellent fibres help prevent moisture absorption while still allowing vapour to escape
• Maintains its shape and density over time, ensuring long-term stability within steel studs
• Semi-rigid design allows quick installation with minimal gaps or slumping
• Manufactured from naturally occurring stone and recycled materials to support sustainable construction
• Suitable for a wide range of steel-frame applications in homes, offices, schools, and industrial buildings
