U-Value (Ug, W/m2 K)
Is the glazing parameter that characterizes the heat transfer through the central part of the glazing, i.e. without edge effects, and expresses the steady-state density of heat transfer rate per temperature difference between the environmental temperatures on each side. The lower the value, the greater is the insulating value.
