100mm Knauf DriTherm 32 Ultimate Cavity Slab is a high-performance insulation product specifically designed for use in external full-fill masonry cavity walls. These water-repellent glass mineral wool slabs provide exceptional thermal performance, making them an ideal choice for enhancing energy efficiency in both residential and commercial buildings. The DriTherm 32 slabs are lightweight and easy to handle, facilitating straightforward installation between wall ties in cavity walls. They offer effective resistance to heat loss, helping to maintain comfortable indoor temperatures while reducing energy consumption and associated costs. Additionally, the slabs contribute to improved acoustic performance, minimising sound transmission between spaces.

Knauf DriTherm 32 is non-combustible, with a Euroclass A1 reaction to fire classification, which ensures a high level of safety in building applications. The product is designed to be moisture-resistant, preventing the risk of condensation and mould growth within the wall structure, thereby ensuring the longevity and durability of the building fabric. Furthermore, DriTherm 32 is odourless, rot-proof, and non-hygroscopic, meaning it does not absorb moisture from the air. It does not sustain vermin and will not encourage the growth of fungi, mould, or bacteria, contributing to a healthier indoor environment. Manufactured using Knauf's unique bio-based binder, ECOSE Technology, DriTherm 32 is an environmentally friendly option that reduces the use of petrochemical products, contributing to a more sustainable construction approach. Due to its lower thermal conductivity, it is often preferred for applications where higher thermal performance is required, such as in energy-efficient buildings or where space is limited.

APPLICATION

  • Masonry cavity external walls, fully filling the cavity
  • For use in buildings up to 12m high in any exposure zone
  • For use in multi-storey applications up to 25m in height

CHARACTERISTICS

  • Odourless: Ensures a pleasant indoor environment.

  • Non-Combustible: Provides a high level of fire safety with a Euroclass A1 reaction to fire classification.
  • Water-Repellent: Contains a silicone binder that prevents water from passing through the slab and reaching the inner leaf of masonry.
  • Pest Resistant: Does not sustain vermin and will not encourage the growth of fungi, mould, or bacteria.
  • Vapour Permeable: Virtually no vapour resistance allows water vapour to pass freely through the slab, enabling the wall to breathe.
  • No Capillary Action: Prevents moisture movement across the cavity or from below the damp proof course (DPC) level.
  • Environmentally Friendly: Does not contain ozone-depleting substances or greenhouse gases.
