Choose the Right Wall Insulation

The best wall insulation depends on the wall construction, available installation space, required thermal performance and project specification. PIR boards offer high thermal resistance for their thickness, while mineral wool products can provide thermal and acoustic insulation. Insulated plasterboard combines insulation with a plasterboard lining, helping simplify certain internal drylining applications.

Before choosing a product, check the manufacturer's technical datasheet, required thickness, fire performance and compatibility with the proposed wall system.

Browse our wall insulation range to compare products, specifications and pack coverage. Trade customers can contact our team for help with product selection and quantity quotations.
