Masonry cavity walls


Glass Mineral Wool


DriTherm® Cavity Slab 32 is a water-repellent Glass Mineral Wool slab, designed for use in external full-fill masonry cavity walls, that offers the best thermal performance in the range.

It is non-combustible with the best possible Euroclass A1 reaction to fire classification, and is manufactured using Knauf Insulation’s unique bio-based binder, ECOSE® Technology.


  • Cavity barriers are not required with non-combustible full fill insulation, minimising the risk of fire spreading through a cavity.
  • Water repellent and BBA certified for use in all exposure zones, including those in very severe areas.
  • Slabs are sized to fit between wall ties without the need for retaining discs.
