U-Value Calculations (External Wall Insulation)

Home > Technical Support > U-Value Calculations

U - VALUE CALCULATIONS

To put it simply, U-Value is the measure of the rate of heat loss through a material.

Therefore, in all aspects of home design one should be aiming for the lowest U-Values possible, because the lower the U value - the less heat is needlessly escaping.

The calculation of U-Values can be rather complex - as it is measured as the amount of heat lost through a one square meter of the material for every degree difference in temperature either side of the material.

WBS offer FREE U-Value Calculations for External Wall Applications only.

U-Value comparisons for domestic refurbishment projects can be found in the EWI Refurbishment - U-Values section of this site.
