Changes to the way you can order
Due to increased delivery costs, we need to implement a minimum order value across our product ranges. The minimum order value is £200 (ex VAT) / £240 (inc VAT). This will enable us to continue to keep our prices low and our service levels high. We thank you for your business and continued support during these unprecedented times.


Insulation boards are used to provide thermal insulation to domestic and commercial buildings and can be used to insulate lofts, walls, floors and ceilings. They are traditionally made from glass fibre or foam plastics. Manufactured as boards for easy transportation, they are usually cut on-site to the specific requirements of the fitter.

We can offer thermal and acoustic insulation for lofts, floors, ceilings and pipes, as well as tank jackets, frost blankets and specialist waterproof insulation products for wet rooms.

We offer products from leading insulation manufacturers, including Kingspan Insulation, Celotex, Rockwool, Knauf Insulation and Marmox.

Innovative products and natural insulation are also available from our extensive stock holding.
