A Guide to Knauf Dritherm Insulation

New external walls on residential and commercial properties require cavity insulation, whether new build or extension, so that construction meets Building Regulations relating to heat loss.

Buildbase supplies Knauf Dritherm cavity slabs; a non-combustible glass mineral wool slab. Dritherm incorporates the environmentally friendly Ecose technology as well as a water repellent additive, suitable to prevent slabs being damaged during construction and making them perfect for external wall construction. Full-fill insulation, installed as the wall is built, prevents mortar and debris bridging the cavity thereby creating a moisture bridge.

As well as top-class thermal performance, Dritherm is sized to fit between wall ties without the need for retaining discs, reducing cost and saving time on site.

Buildbase stocks Dritherm 32 Ultimate and Dritherm 37 Standard. 32 Ultimate offers the best thermal efficiency, the slightly higher price brings long-term savings. All new build homes should be specified with Dritherm 32.

37 Standard is mainly used in extensions. It offers a lower thermal performance but retains the water repellent additive and A1 fire rating at a lower price point.
