Rockwool RWA45 Insulation Slab

Rockwool RWA45 Insulation Slabs are versatile and reliable solutions for acoustic, thermal, and fire protection across a broad range of building applications. These stone wool slabs are designed for use in walls, ceilings, floors, and roofs, offering excellent performance and adaptability to meet various construction needs.

With a nominal density of 45kg/m³ and thermal conductivity of 0.035 W/mK, RWA45 slabs provide exceptional thermal efficiency while ensuring long-term reliability. The non-combustible stone wool composition achieves a Euroclass A1 fire classification, delivering peace of mind in fire safety. Additionally, their non-directional fibre structure and density effectively trap sound waves, reducing external noise and enhancing acoustic comfort for building occupants.

Available in standard dimensions of 1200 x 600mm (or 1000 x 600mm for faced options), the slabs come in a variety of thicknesses and densities to suit diverse project requirements. Custom-facing options, including black or white tissue and aluminium foil, are also available on request, subject to minimum order quantities and production compatibility*.

Rockwool RWA45 Insulation Slabs are designed to retain their shape and thickness for the lifetime of the building, ensuring consistent thermal and acoustic performance over decades. Whether you’re constructing partitions, insulating floors, or enhancing the fire protection of a roof, these slabs are a trusted choice for building professionals seeking durability, efficiency, and adaptability.
