ADVANTAGES

1. Non-combustible full-fill insulation removes the requirement for cavity barriers, substantially lowering fire spread risks within the cavity space.
2. BBA-certified and water-resistant, enabling installation across all exposure conditions, including extremely harsh coastal and weather-exposed zones.
3. Precisely dimensioned 85mm slabs align perfectly with wall tie spacing, eliminating the need for retaining discs during installation.

About

The 85mm Knauf DriTherm 37 Ultimate Cavity Insulation Slab is a water-resistant glass mineral wool product specifically engineered for complete-fill applications in external masonry cavity walls. Boasting a certified thermal conductivity rating of 0.037W/mK, it delivers reliable thermal protection.

This 85mm DriTherm 37 Cavity Slab combines durability with practical benefits: it's odourless, rot-resistant, non-hygroscopic, and vermin-proof. The material naturally resists fungal growth, mould, and bacterial colonisation.

Built using Knauf ECOSE Technology, these Cavity Wall Slabs deliver outstanding Euroclass A1 fire performance. With BBA certification for all exposure zones including severe maritime conditions, they're approved for buildings up to 12m in any exposure zone and multi-storey structures reaching 25m in height.

These insulation slabs contain no ozone-depleting substances or greenhouse gas emissions. Knauf glass and rock mineral wool products stand out for straightforward installation compared to rigid board alternatives. The Knauf DriTherm Cavity Insulation Slabs conform to uneven surfaces, bonding together to seal air gaps and prevent thermal bridging.

Durability

The 85mm Knauf DriTherm Slabs deliver outstanding longevity with odourless, rot-resistant, non-hygroscopic properties and natural vermin resistance. They actively prevent fungal, mould, and bacterial growth.

Application

Intended for thermal insulation in masonry cavity external walls, these 85mm DriTherm Slabs are positioned to fully occupy the cavity space. They're certified for buildings up to 12m in any exposure zone (subject to BBA certification compliance) and work equally well in multi-storey applications up to 25m in height.
