U-VALUE OR THERMAL TRANSMITTANCE OR AIR-TO-AIR HEAT TRANSMISSION COEFFICIENT
A figure determined by experiment for a certain wall, roof, or floor in a certain situation, which tells how many watts per hour will pass through one square metre of the wall when the temperature difference of the air between both sides is 1°c.
NOTE: In an exposed situation, the same wall will have a higher U-Value than in a sheltered situation.
