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.
