We provide free of charge U value calculations and condensation risk analyses. This service is to help you confirm compliance with Building Regulations when using our products for your construction projects.

All calculations are carried out in accordance with the relevant standards and follow the guidance within BR 443 – Conventions for U Value Calculations.

To provide this service we require as much detailed information about the project and the construction element you would like us to assess.
