Knauf DriTherm 32 150 mm Cavity Slab (2.184 m²)

The Knauf DriTherm 32 150 mm Cavity Slab is a high‑performance insulation product designed for external masonry cavity walls with larger widths. Manufactured from water‑repellent glass mineral wool, it offers a thermal conductivity of 0.032 W/m·K and achieves a thermal resistance of approximately 4.65 m²K/W. :contentReference[oaicite:1]{index=1}

The slabs measure 1 200 mm in length and 455 mm in width, allowing a friction‑fit installation between standard wall ties without the need for retaining discs. They are non‑combustible with a Euroclass A1 fire rating and are BBA‑certified for use in exposure zones including very severe. :contentReference[oaicite:2]{index=2}
