U-value calculations can be performed free-of-charge to show compliance with current Building Regulations / Standards and best practice. They can be supported with a detailed report. One of the easiest ways of getting a u-value calculation is using our free U-value Calculator (Opens in a new window).
U-value calculations must be performed in accordance with BS 6946: 2007 using a method known as the ‘Combined Method’. Calculations should also be carried out in strict accordance with the guidance issued in BR 443 Conventions for U-value Calculations (2006) and should be undertaken by competent persons.
Calculations produced by Kingspan Insulation’s Technical Services Department are approved under the ‘BBA/TIMSA Scheme for Calculation Competency Part 1 - U value and condensation risk’.
