Slash your energy bills with 50mm Knauf Earthwool DriTherm 37 Cavity Wall Insulation Slab; a glass mineral insulation slab offering excellent thermal performance in masonry cavity external walls. The slabs 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 50mm cavity insulation slabs are marshmallow soft (meaning they're a dream to handle) and deliver superior environmental sustainability.
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.
50mm Knauf DriTherm Cavity Slab 37 Applications
50mm 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 in 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 Earthwool DriTherm 37 is conveniently cut at 455mm wide in line with standard wall tie spacings, producing a neatly closed joint with adjacent slabs.
DriTherm 37 50mm Cavity Wall Insulation Slabs Specifications
Knauf DriTherm 37 is a robust glass mineral wool slab specifically designed for installation in external masonry cavity walls.
The slabs knit together with both leaves of an external wall to eliminate air gaps and subsequent heat loss; DriTherm achieves this by fully filling the cavity and knitting together at joints. Despite its cotton soft composition, Dritherm boasts a firmness that ensures it stays put, wherever you position it. Let's take a look at the specs:
- Contains no ozone-depleting substances or greenhouse gases
- BBA certified
- Thermal conductivity of 0.037 W/mK
- Moisture-resistant and rot-proof
- Euroclass A1 Reaction to Fire Classification - fire retardant
- Sized at 1200mm x 455mm - specifically designed to be compatible with standard vertical wall ties without the need for retaining discs
Knauf Insulation DriTherm 37 Certifications
The 50mm 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 a doddle 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, pop them on a level surface and under a protective cover.
