WebU-factors and R-values are used to estimate heat flow under steady-state conditions (neglecting the effects of thermal mass). These steady-state values can be used in conjunction with factors such as thermal mass, … WebU-values.) Uncoated glass is assumed to have a normal emissivity of 0.89. 3. The gas mixture is assumed to consist of 90% argon and 10% air. 4. For doors which are half-glazed the U-value of the door is the average of the appropriate window U-value and that of the non-glazed part of the door (e.g. 3.0 W/m²K for a wooden door). 5.
