Our products - BecoWallform ICF

BecoWallform is an innovative, fast, and cost-effective building system that promotes environmental sustainability and Fabric First design principles.

This monolithic, insulated concrete formwork (ICF) system delivers rapid construction while surpassing the performance metrics of conventional building methods. Constructed from large, interlocking hollow polystyrene blocks, BecoWallform eliminates the need for intermediate bedding materials, streamlining the construction process. Concrete poured into the formwork sets to create a robust structure, with the formwork itself serving as long-lasting thermal insulation, achieving impressive U-values as low as 0.11 W/m²K making it the ideal choice for zero energy and passivhaus buildings.

Wallform represents a sustainable approach to construction, aligning with modern methods of construction (MMC) by utilising materials engineered for longevity and recyclability, ensuring ongoing environmental responsibility.

Frequently asked questions

We are so impressed with the standard of work! We only wonder why we didn’t get it done earlier! The house looks 100% better. Adam and Tom and the guys have been superb. There was the minimum of fuss , they just got on with the job and worked really hard. Rob Ramella was also excellent. He listened carefully and came up with a solution that other companies hadn't.

Again, thanks for a superb job done by friendly people who are totally focused on the customer.
