What Is Knauf DriTherm 37 Insulation?

DriTherm 37 insulation is part of Knauf’s industry-recognised range of cavity wall insulation slabs, made from non-combustible glass mineral wool. Each slab friction fits between wall ties in masonry cavity walls for gap-free coverage that limits heat loss.

The “37” in the slab’s name refers to its low thermal conductivity of 0.037 W/m.K, which provides excellent insulation performance while maintaining breathability.
