WebWhat is a U value? A U value is a measure of heat loss in a building element such as a wall, floor or roof. It can also be referred to as an ‘overall heat transfer co - efficient’ and measures how well parts of a building transfer heat. This means that the higher the U value the worse the thermal performance of the building envelope. WebApr 3, 2024 · The U-value is the “heat transfer coefficient”. It is the reciprocal of “Lambda” – the thermal conductivity. Both are values that apply specifically to a very specific material. Roughly speaking, the following limit values can be assumed: Everything that has a lambda value of 0.004 to 0.07 W/ (m²K) is considered “insulating ...
