Knauf DriTherm 32 125mm Cavity Wall Insulation Slab - 2.18m2

Knauf DriTherm 32 125mm Cavity Wall Slabs are designed to provide outstanding insulation performance in external full-fill masonry cavity walls. Each pack covers 2.18m2, making them well-suited for projects that demand a balance of excellent thermal efficiency and practical coverage.

Offering a thermal conductivity of 0.032 W/mK, these slabs are the most efficient option within the Knauf cavity wall range. Manufactured from water-repellent glass mineral wool, they help prevent moisture penetration while maintaining reliable long-term performance. With a Euroclass A1 fire rating, they deliver maximum fire safety alongside superior energy savings.

Fully BBA certified for use across all exposure zones, including areas subject to severe weather, DriTherm 32 slabs are built for durability. Their semi-rigid design adapts to irregularities within the wall cavity and knits tightly together, eliminating gaps that could reduce performance. Installation is simple, with a friction-fit design that holds securely between wall ties without the need for retaining discs or jointing tape.
