About

The 85mm Knauf DriTherm 32 Ultimate Cavity Insulation Slab is a water-repellent glass mineral wool product for full-fill use in external masonry cavity walls. With thermal conductivity of 0.032W/mK, it delivers reliable thermal performance.

This cavity slab is durable, odourless, rot-resistant, non-hygroscopic, and vermin-proof. It resists fungal, mould, and bacterial growth.

Built with Knauf ECOSE Technology, these Cavity Wall Slabs achieve Euroclass A1 fire classification. BBA certified for all exposure zones including very severe areas, they're approved for buildings up to 12m in any exposure zone and multi-storey buildings up to 25m high.

These slabs contain no ozone-depleting substances or greenhouse gases. Knauf glass and rock mineral wool offer easier installation than rigid boards. The Knauf DriTherm Cavity Insulation Slabs conform to substrate irregularities, bonding together to prevent air gaps and thermal bridging.

Durability

These 85mm slabs are odourless, rot-resistant, non-hygroscopic, vermin-resistant, and prevent fungal, mould, and bacterial growth.

Application

Designed for thermal insulation in masonry cavity external walls, these slabs are installed to fully fill the cavity. They're approved for buildings up to 12m high in any exposure zone (subject to BBA certification) and suitable for multi-storey applications up to 25m.
