85mm thick Knauf DriTherm 37 cavity slabs with a total coverage of 4.37m². Semi-rigid and rigid glass mineral wool slabs well-known for their water-repellent and non-combustible qualities. They are excellent for conventional upright wall tie spacings, ensuring a secure joint with adjoining slabs.

  • Coverage: 4.37m²

100mm 12 boards 6.55

Suitable for structures up to 12m high in any exposure zone and multi-storey uses up to 25m. As a pro tip, remember that tightly knitting the slabs together eliminates air gaps within the neighbouring slabs ensuring stronger and better insulation.

DriTherm Cavity 37 Slabs pose no threat to the environment and contribute zero Ozone Depletion Potential (ODP) and have a low Global Warming Potential. Knauf Insulation mineral wool is created by making use of a bio-based and innovative formaldehyde-free binder technology. The raw materials for these Knauf Insulation cavity slabs are renewable materials, rather than petroleum-based compounds. The glass mineral wool water-repellent insulation slabs pass on higher environmental sustainability making them extremely eco-friendly.
