The Knauf DriTherm 32 Cavity Slab is a glass mineral wool insulation product designed for installation in external masonry cavity walls. Supplied in pack sizes of 1200 x 455 x 75mm (covering 3.28m²), it is suitable for use across domestic and commercial projects where cavity wall insulation is required.
These slabs are straightforward to handle and fit between wall ties, supporting efficient site installation. Their water repellent properties help manage moisture within the cavity, while the slab design ensures a close fit to minimise gaps for consistent insulation coverage.
