Knauf DriTherm 32 75 mm Cavity Slab (3.276 m²)

This Knauf DriTherm 32 75 mm Cavity Slab is a high‑performance insulation solution designed for full‑fill installation in external masonry cavity walls. Manufactured from water‑repellent glass mineral wool using ECOSE® binder technology, it offers a thermal conductivity of 0.032 W/m·K and a thermal resistance of approximately 2.30 m²K/W. :contentReference[oaicite:1]{index=1}

The slab size is 1,200 mm in length and 455 mm in width, tailored to fit between standard vertical wall‑tie centres and to give a friction‑fit installation without the need for retaining discs. It is certified non‑combustible (Euroclass A1) and fully BBA‑approved for use in all exposure zones, including very severe conditions. :contentReference[oaicite:2]{index=2}
