3. 100mm slabs are precisely sized to sit between wall ties without requiring retaining discs, streamlining installation.

About

The 100mm Knauf DriTherm 37 Ultimate Cavity Insulation Slab is a water-repellent glass mineral wool product made for full-fill external masonry cavity walls. It delivers reliable thermal performance with a certified thermal conductivity rating of 0.037W/mK.

This 100mm cavity slab is exceptionally durable, odourless, rot-resistant, non-hygroscopic, and vermin-proof. It naturally resists fungi, mould, and bacterial growth.

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

These insulation slabs contain no ozone-depleting substances or harmful greenhouse gases. Knauf glass and rock mineral wool installation is simpler than rigid board alternatives. The Knauf DriTherm Cavity Insulation Slabs conform to surface irregularities, bonding together to prevent air gaps and thermal bridging.

Durability

The 100mm Knauf DriTherm Slabs are odourless, rot-resistant, non-hygroscopic, vermin-proof, and inhibit the development of fungi, mould, and bacteria.

Application

Intended for thermal insulation in masonry cavity external walls, 100mm DriTherm Slabs are fitted to completely fill the cavity space. They're certified for buildings up to 12m in any exposure zone (subject to BBA certification compliance) and work well for multi-storey buildings reaching 25m in height.
