CBA U-Value Calculator

Welcome to the CBA U-value calculator. This simple tool will enable you to calculate the potential U-value for a cavity masonry wall based on a number of parameters. It includes an option to select a 'Basic Wall' which is based upon a brick, fully filled 100mm cavity and 100mm inner leaf block construction. This simplified U-value calculator uses BS EN ISO 6946 procedures and the latest version of the U-value conventions but incorporates generic material values. We recommend that you check any U-values using product specific values before using them as part of a calculation for obtaining building control approval.
