Knauf DriTherm® Cavity Slab 34 is designed for use in full-fill masonry cavity walls.
The slab is installed between wall ties within the cavity, where it forms part of the external wall build-up. Its flexible structure allows the slabs to knit together during installation, helping reduce gaps and maintain a consistent insulation layer across the wall area.
Suitable for residential, commercial and industrial projects, DriTherm® Cavity Slab 34 provides a practical cavity wall insulation solution with moisture resistance and Euroclass A1 fire performance. Its BBA certification allows use across all exposure zones, including very severe areas.
