What Is 75mm Knauf DriTherm 37?
75mm Knauf DriTherm 37 is a robust glass mineral wool slab specifically designed for installation in external masonry cavity walls.
They can be used in buildings up to 12m in any exposure zone, as well as multi-story applications up to 25 metres tall.
The "Therm 37" relates to the product's thermal conductivity value of 0.037 W/mK whilst the 'Dri' refers to the slab's water-repellent additive, added to maximise its overall thermal performance.
Manufactured by Knauf Insulation using unique ECOSE technology, Knauf DriTherm 37 75mm cavity insulation slabs are soft to the touch while delivering superior environmental sustainability.
Despite their cotton soft composition, Dritherm slabs boast a firmness that ensures they stay put, wherever you position them.
These slabs knit together with both leaves of an external wall to eliminate air gaps and subsequent heat loss; DriTherm achieves this by filling the cavity and knitting together at joints.
Boasting an impressive A1 Euroclass classification, these BBA-certified slabs eliminate the need for cavity barriers with non-combustible full-fill insulation, minimising the risk of fire spreading through a cavity.
Where is 75mm Knauf DriTherm Cavity Slab 37 Used?
75mm Knauf Dritherm Cavity Slab 37 is purposed for use in masonry cavity walls where a full-fill insulation solution is required.
A masonry cavity wall is made up of two leaves (or skins); an inner leaf and an outer leaf. The "cavity" is simply the gap between these two walls.
They are considered to be an effective thermal insulation solution for buildings up to 12m high and in multi-storey applications up to 25m high.
Knauf DriTherm 37 is conveniently cut at 455mm wide in line with standard wall tie spacings, producing a neatly closed joint with adjacent slabs.

- BBA certified
- Thermal conductivity of 0.037 W/mK
- Moisture-resistant and rot-proof

Knauf Insulation DriTherm 37 Certifications
75mm DriTherm 37 Cavity Slab is manufactured in accordance with BS EN 13162, ISO 50001 Energy Management Systems. They have zero Ozone Depletion Potential (ODP) and zero Global Warming Potential (GWP) meaning they're perfectly environmentally friendly.
The slabs also carry a British Board of Agrément (BBA) certification, which is a nationally recognised stamp of approval for reliability and quality.
The slabs are BBA certified for use in all exposure zones, including those in very severe areas. cavity barriers
Knauf DriTherm 37 Storage & Handling
As glass mineral wool is quite lightweight, the packs are easy to handle and move around. However, when it comes to moving pallets, a forklift should be used to prevent injury. Alternatively, the pallet can be split into packs which can then be moved individually.
Slabs are supplied in polythene shrink wrap for short-term protection. We advise that you store them indoors. As we know that's not always possible, our rule of thumb when it comes to storing outdoors is to keep the slabs above ground. Simply, store them on a level surface and under a protective cover.
