The BFRC Window Energy Rating scheme provides a straightforward method for manufacturers to demonstrate the energy performance of a window.
Taking into account heat loss from the window through thermal transmittance (U value) and air leakage, together with heat gained from the sun (Solar gain), the scheme gives A to G ratings for windows in a clear format.
