Fabric Bench

Fabric Bench

Build up a wall, flat or pitched roof, or floor from real materials and read off the U-value, calculated to BS EN ISO 6946 (and BS EN ISO 13370 for ground floors).

Fabric Bench is a free tool from Workbench. Figures are calculated from the material properties you enter using standard UK methods (BS EN ISO 6946 / BS EN ISO 13370) — always confirm against your manufacturer's datasheet before relying on a result for Building Regulations compliance or a SAP/PHPP submission.
