150mm Knauf DriTherm Cavity Wall Insulation Slab 32 (2.18m2/Pack)

Full-fill glass mineral wool insulation slab, measuring 150mm in thickness, for use in masonry cavity walls.Manufactured with a high recycled glass content and ECOSE® Technology, it delivers advanced thermal insulation while remaining vapour permeable, helping the wall construction to breathe.With a thermal conductivity of 0.032 W/mK, it provides superior energy efficiency, enabling lower U-values to be achieved at reduced insulation thicknesses.Rated Euroclass A1 non-combustible and fully BBA certified for all UK exposure zones, it ensures proven fire safety, durability, and long-term reliability.At 150mm thick, the largest slab in the DriTherm 32 range, it is designed for wider cavity walls in new build housing. This depth provides the highest level of thermal performance, helping developments meet stricter Building Regulation requirements while allowing full-fill installation in a single layer for easier, faster fitting.
