Description
DriTherm® Cavity Slab 32 is a high-performance glass mineral wool insulation designed for full-fill external masonry cavity walls. With its water-repellent formulation and unfaced finish, it’s suitable for buildings up to 12m high in any exposure zone and up to 25m high in multi-storey applications.
Lightweight, rot-proof, and odourless, these slabs are easy to cut and install, fitting snugly between wall ties to minimise air gaps and maximise performance. Thanks to their non-combustible Euroclass A1 fire rating, cavity barriers are not required, as the risk of fire spread within the cavity is negligible.
Manufactured with ECOSE® Technology, DriTherm® slabs are free from harmful chemicals, ozone-depleting substances, and greenhouse gases, making them a safe and sustainable insulation choice. Approved by the BBA, they deliver reliable performance across all exposure zones, even in severe conditions.
