This calculation has been produced by an independent company and are based on timber frame walls designed by ACJ Group incorporating wool products and a generic polyurethane foam. The U-value is based on a range of enhanced U-values in the floors, walls, and roofs. The U-values for the floors and roofs are standardised for ease of use elements. The calculations were undertaken using software in accordance with BS EN 10211 and BR 497.Calculations based on insulated concrete ground floor by other.
