FAQs

What is the thermal conductivity of this slab?

The thermal conductivity of the Knauf DriTherm Cavity Slab 32 - 75mm is 0.032 W/mK.

Can this product be used in any exposure zone?

Yes, it is Agrement certified by the BBA for use in all exposure zones in the UK, including very severe areas.

Does this insulation require cavity barriers?

No, this is a full-fill solution and does not require additional cavity barriers when installed as per the manufacturer's guidelines.

Is this product fire-safe?

Yes, it is rated Euroclass A1 non-combustible, ensuring a high level of fire safety.

What makes this slab adapt to wall imperfections?

The high-density, engineered nature of the slab allows it to compress slightly and knit together, filling any minor gaps in the substrate.

What is ECOSE® Technology?

ECOSE® Technology refers to the binder used in the manufacturing process, which is formaldehyde-free and uses a bio-based material, contributing to a more sustainable product with reduced environmental impact.

Is this slab suitable for new builds or just renovations?

It is suitable for both new builds and refurbishment projects, particularly where cavity widths are limited or non-standard, thanks to its 75mm thickness.

Troubleshooting

Slab does not fit snugly

Ensure the cavity is free from obstructions. If the cavity is wider than intended for the slab, it may not achieve a sufficient friction fit and alternative solutions might be needed.

Concerns about moisture ingress

While the slab is vapour permeable, ensure proper external weatherproofing of the building. The BBA certification covers use in severe exposure zones, indicating robustness against weather.

Difficulty cutting the slab

Use a sharp insulation knife or saw designed for cutting mineral wool. Score and snap for cleaner cuts if necessary. Wear appropriate personal protective equipment (PPE).
