Knauf DriTherm Cavity Slab 37 75mm 1200mm x 455mm (4.36m2)

Knauf DriTherm Cavity Slab 37 is the ultimate solution for external full-fill masonry cavity walls. With the best possible Euroclass A1 fire classification and its water-repellent additive, this non-combustible glass mineral wool slab is designed to resist moisture ingress, maintaining its integrity and thermal properties in any exposed areas. The slabs themselves are easier to install than rigid boards and are designed to fit tightly between wall ties and any imperfections to ensure a clean finish. Most importantly, due to the structure of the slabs, Knauf ensure a high standard thermal performance eliminating any air gaps.
