Knauf Insulation DriTherm Cavity Slab - 150mm

ECOSE® Technology is Knauf Insulation's patented binder system that uses a formaldehyde-free, bio-based binder. Products made with this technology are soft to touch, generate low levels of dust, and have low VOC emissions, contributing to a healthier indoor environment.

The 150mm slab is designed for new build housing with wider cavities. For existing homes with narrower cavities, thinner slabs from the Knauf Insulation DriTherm range are generally more appropriate.

The thermal conductivity of the Knauf Insulation DriTherm Cavity Slab - 150mm is 0.037 W/mK.

The water repellent additive is integrated into the glass mineral wool during manufacturing. It helps to resist the passage of liquid water through the slab, protecting the insulation's performance from moisture ingress, while still allowing water vapor to escape.

This product has a Euroclass A1 Reaction to Fire classification rating, which is the highest possible rating for construction products, meaning it is non-combustible.

No, the slabs are sized to fit between wall ties without the need for additional retaining discs, simplifying the installation process.

The British Board of Agrément (BBA) approval confirms that the product is suitable for its intended use in all exposure zones within the UK, providing assurance of its performance and durability.

Verify the cavity width and wall tie spacing. Ensure no debris is obstructing the cavity. If the cavity is too narrow, this product is unsuitable; consider a thinner slab from the DriTherm range.

Ensure slabs are butted tightly together. If necessary, cut small pieces to fill any minor gaps, maintaining a continuous insulation layer.

While manufactured with water-repellent additives, prolonged exposure to rain can saturate the material. Allow slabs to dry thoroughly in a well-ventilated area before installation. Check packaging integrity.

Use a sharp, purpose-made insulation knife or a fine-toothed saw. Cutting on a flat surface with a straight edge can improve accuracy.
