Knauf DriTherm 37 150mm Cavity Wall Insulation Slab - 4.37m2

Knauf DriTherm 37 150mm Cavity Wall Slabs are a high-performance insulation solution for full-fill masonry cavity walls. Each pack provides 4.37m2 of coverage, making them suitable for projects that require thicker insulation to achieve improved energy efficiency.

These water-repellent glass mineral wool slabs offer a thermal conductivity of 0.037 W/mK, reducing heat loss and helping to lower energy costs. They are non-combustible, achieving a Euroclass A1 fire rating, and are manufactured using Knauf’s ECOSE® Technology for a more sustainable build.

Fully BBA certified, DriTherm 37 slabs are approved for use in all exposure zones, including those subject to very severe weather. The semi-rigid design allows them to knit together within the cavity, eliminating air gaps and maintaining continuous thermal performance. Friction-fit installation between wall ties ensures they stay securely in place without the need for retaining discs or additional fixings.
