One of the easiest and most cost-effective forms of insulation to install in the home is cavity wall insulation. 75mm Knauf Earthwool DriTherm 37 Cavity Wall Insulation Slab offers excellent thermal performance in masonry cavity external walls and can be used in buildings up to 12m in any exposure zone, as well as multi-story applications up to 25 metres tall. 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. 

Manufactured by Knauf Insulation using unique ECOSE technology, Knauf DriTherm 37 75mm cavity insulation slabs are buttery soft (meaning the only itch these slabs will give you is the itch to buy more) and provide superb protection for the lifetime of your build. 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.

75mm Knauf DriTherm Cavity Slab 37 Product Description


Knauf DriTherm 37 is a glass mineral wool slab suitable for installation in external masonry cavity walls. It acts as effective thermal insulation and is BBA certified for use in buildings up to 12m high in any exposure zone - including very severe areas - and in multi-storey applications up to 25m high.

Manufactured by Knauf Insulation with a lambda value of 0.037 W/mK, it offers excellent thermal performance. The slabs are 1200mm x 455mm, and are specifically designed to be compatible with standard vertical wall ties without the need for retaining discs, ensuring a closed joint with adjacent slabs. Their sizing also helps to eliminate air gaps.

These glass mineral wool slabs have a reaction to fire classification of A1 non combustible on the Euroclass scale. This fire rating means that they do not burn, which prevents fire spreading and protects vulnerable exposure zones. They are also water repellent and rot proof.

75mm DriTherm 37 Cavity Slabs come in a pack quantity of 8, giving a total pack coverage of 4.37m2.

Knauf DriTherm Cavity Slab 37 Applications

75mm Knauf Dritherm Cavity Slab 37 is typically installed 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 inner leaf is the one that carries the building structure and is typically constructed using standard concrete blocks. The outer leaf comprises brickwork; these will usually be facing bricks that have some aesthetic value, the term "facing brick" coming from the fact that they face outwards and are therefore visible. The gap in between these walls is called the "cavity".

Cavities can either be partially filled or fully filled with insulation. Partially filled cavities leave an air gap between the insulation and the outer leaf, whereas fully filled cavities do not leave an air-gap. These Earthwool DriTherm Cavity Slabs are designed to fully fill the cavities. This means that if the size of your cavity is 75mm, the 75mm Dritherm 37 will suit your purposes.

Knauf DriTherm 37 Certifications

The 75mm DriTherm 37 Cavity Slab are 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).

These slabs carry a British Board of Agrément (BBA) certification, which is a nationally recognised stamp of approval for reliability and quality.

Knauf DriTherm 37 Storage & Handling

The 75mm Dritherm 37 slabs are sold in packs of 8. Each pack covers 4.37m2. Glass mineral wool insulation is a lightweight material and the packs can be handled fairly easily. When moving pallets, a forklift or other machinery is necessary. Alternatively, the pallet can be broken down into packs which can then be moved individually.

The slabs are wrapped in polythene packs that offer short term protection. However, for longer term storage, the packs should be stored indoors or under cover, ideally off the ground. They should not be left permanently exposed to the elements.
