Knauf DriTherm 32 75mm Cavity Wall Insulation Slab - 3.28m2

Knauf DriTherm 32 75mm Cavity Wall Slabs are an effective insulation choice for external full-fill masonry cavity walls, offering a balance of performance and practicality. Each pack provides 3.28m2 of coverage, making them ideal for medium to large projects where energy efficiency and compliance are priorities.

With a thermal conductivity of just 0.032 W/mK, these slabs deliver premium insulation performance within the Knauf range. Made from water-repellent glass mineral wool, they resist moisture while maintaining consistent thermal efficiency. They are also non-combustible, holding a Euroclass A1 fire safety rating.

BBA approved for use across all UK exposure zones, including severe weather areas, DriTherm 32 slabs are engineered for long-term reliability. Their semi-rigid design enables them to adjust to surface irregularities and knit tightly together in the cavity, closing gaps that could compromise performance. Quick to install, the friction-fit system ensures a secure hold without the need for extra retaining products.
