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.

Loft Insulation

Loft Insulation

Loft insulation is effective for at least 40 years. The National Insulation Association found that cavity wall and loft insulation could be exceptionally cost effective, with the initial cost of insulation being repaid within just three years. Choose from rolls of mineral wool insulation, rigid insulation board or thermal insulation rolls depending on your needs.

Cavity Insulation
