DuoDuct Slab is a rigid stone wool insulation slab designed for the thermal and acoustic insulation of ventilation ductwork. Manufactured from volcanic rock, the material is non-combustible and achieves a Euroclass A1 reaction to fire classification in accordance with BS EN 13501-1. It is CE marked in accordance with EN 14303:2009+A1:2013, confirming compliance with European standards for thermal insulation products for building equipment and industrial installations.
The stone wool core supports efficient temperature control within air distribution systems, helping to reduce heat loss and associated operational energy demand. DuoDuct Slab is dimensionally stable, moisture resistant, and durable, supporting long service life and reducing the need for replacement. At end of life, the material is fully recyclable and its manufacture incorporates recycled content, aligning with ROCKWOOL’s wider commitments to circularity and resource efficiency.
