U-value Calculation

U-value Calculations evaluate the thermal performance of a building element, such as a roof, floor or wall. The building regulations require you to prove the thermal performance obtained by a building element, and a U-value calculation provides this proof.

Our U-value calculations are carried out in accordance with BRE443:Conventions for U-value Calculations and can be submitted with your building control applications to demonstrate compliance.

U-value calculations are provided free of charge where our products are being used.
