Knauf 34 Super Earthwool Dritherm Cavity Slab

Earthwool Dritherm Cavity Slabs are semi-rigid or rigid insulation slabs crafted from non-combustible, water-repellent glass mineral wool. Designed at 455mm in width, they align perfectly with standard vertical wall tie spacings, ensuring tight joints with adjacent slabs. These slabs are specifically engineered for the thermal insulation of masonry cavity walls and are installed to fully fill the cavity. Earthwool Dritherm Cavity Slabs are environmentally friendly, with zero Ozone Depletion Potential (ODP) and zero Global Warming Potential (GWP).
