R-Wall ICF System: Award-Winning Insulation and Construction

R-Wall is a UK‑based, family-run business that has developed a new and improved Insulated Concrete Formwork (ICF) system designed for high-performance modern construction. Launched in 2020, the R-Wall system has rapidly gained industry recognition, winning Best Insulation Product and serving as the structural solution for the award-winning project Ebron ha Mòr. These accolades highlight R-Wall’s excellence in sustainability, thermal performance, and build quality.

At its core, R-Wall delivers a low-carbon build method using 93% recycled plastics combined with BREEAM A-rated insulation, fully compliant with current building regulations and designed to meet future standards. The super-fast construction process—with components unaffected by weather—ensures projects progress efficiently and without delay.

Homes built with R-Wall outperform many traditional methods in strength, longevity, and energy efficiency. Structural closed-cell insulation enhances formwork strength, provides guaranteed thermal performance with zero cold bridging, and promotes healthier living environments. R-Wall buildings do not suffer from post-construction movement, rot, or degradation, offering an expected lifespan of over 60 years and significantly reduced running costs.

R-Wall’s versatility is exceptional. Using just four core components it can create detached and semi-detached homes, flats up to 11m, commercial buildings, extensions, basements, retaining walls, pools, cantilevers, and curved or angled designs—all without increasing cost. Insulation options from 50mm to 150mm, combined with core thicknesses from 4” to 12”, achieve U-values as low as 0.09 within slim wall assemblies.

Fully BBA approved, an ICFA member, and accepted by warranty providers, building control, and mortgage lenders, R-Wall offers a proven, award-winning solution for high-performance
