Insulate external full-fill masonry cavity walls with Knauf Insulation DriTherm Cavity Slab 32, supplied in a 1200 x 455 x 150mm size. This high-performance glass mineral wool slab offers a thermal conductivity of 0.032 W/m.K, delivering low heat transmission for energy-efficient wall constructions.

Manufactured with a water-repellent additive to resist moisture ingress, the slab is engineered to adapt to slight imperfections in the substrate and knit together at joints. This eliminates air gaps and preserves thermal performance for the lifetime of the building. The slab friction-fits securely between wall ties without needing ancillary products such as retaining discs or jointing tape, providing a full-fill solution that does not require cavity barriers.

DriTherm Cavity Slab 32 holds a BBA Agrément certificate for use in all exposure zones, including very severe environmental areas. Non-combustible with a Euroclass A1 fire rating, it holds a CCPI Verification Mark and is manufactured using Knauf Insulation's unique bio-based binder, ECOSE Technology.
