About this product

The Knauf Dritherm Cavity Slab 37 is a semi-rigid insulation slab made from glass mineral wool, designed for full-fill cavity wall insulation on masonry builds. The slabs measure 1200mm x 455mm with a thickness of 150mm and offer a thermal conductivity of ~0.037 W/mK, significantly reducing heat loss. Installation can also help to reduce overheating in summer. Knauf Dritherm cavity slabs are non-combustible, with an A1 fire rating. They’re also treated with a water-repellent additive that stops them absorbing water or promoting damp issues. Easy to handle and install, these slabs are ideally suited to improving energy efficiency on residential or commercial builds.
