U-Values

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.
