R-WALL is a UK-designed and manufactured Insulated Concrete Formwork (ICF) system, founded by a builder and an environmental scientist with the goal of creating a better way to build. Launched in 2020, the system is designed to deliver faster build times, improved energy efficiency, reduced reliance on skilled labour, and a significantly lower carbon footprint, meeting current regulations and future-proofing for forthcoming standards. The R-WALL system is non-modular, formed from XPS insulation (R-Board) connected by R-Rails and R-Ties, filled with concrete to create a monolithic structure.
1, and exceptional thermal performance and airtightness. The integrated R-Rails provide fixing points for finishes, and services can be chased into the insulation, simplifying the build process. The system is versatile, suitable for residential builds, extensions, basements, commercial properties, pools, ponds, and retaining walls, with the ability to create complex shapes like curves and angles.
With a commitment to local production, R-WALL minimizes its carbon footprint while maintaining high product standards and a reliable supply chain. The company provides tailored training and on-site support, working closely with architects, engineers, and warranty providers. R-WALL has seen rapid growth driven by industry recommendation, with completed builds ranging from individual homes to multi-storey developments nationwide.
