Cavity Insulation

We stock a vast range of cavity wall insulation products in order to meet the demands of all projects. We are working closely with leading insulation cavity manufacturers Knauf Insulation and Xtratherm to provide a multitude of premium quality products at very competitive prices.

One of the items that Buildbase suppliers is Knauf Dritherm cavity slabs; a no combustible glass mineral wool slab. Dritherm incorporates the environmentally friendly Ecose technology, as well as a water repellent additive, suitable to prevent slabs from 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.

We stock 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 extension. If offers a lower thermal performance but retains the water repellent additive and A1 fire rating at a lower price point.

For completing your projects, you can also view our range of plaster, plasterboard and drylining screws.

With so many options for insulation, it’s important to choose the correct one for your project. Please read our guide to insulation.

If you cannot find the product you require or are unsure which product to use, please contact your local branch for assistance. Locate your branch using our branch locator. Or alternatively book an appointment with an expert.
