This label will display the following information:

The rating level – A, B, C, etc…

The energy rating eg. -3kWh/(m²·y) in this example the product will lose three kilowatt hours per square metre per year.

The window U value eg. 1.4W/(m²·K)

The effective heat loss due to air penetration as L eg. 0.01 W/(m²·K)

The solar heat gain eg. g=0.43
