In an make an effort to give a handy comparison concerning option window constructions the British Fenestration Ranking Council have described a "Window Energy Ranking" WER, ranging from A for the most effective down through B and C etc. This takes into account a mix of the heat decline in the window (U value, the reciprocal of R-value), the photo voltaic get (g value), and loss through air leakage around the body (L benefit). One example is, an A Rated window will in an average calendar year gain just as much heat from solar get since it loses in other approaches (nonetheless the vast majority of this gain will take place through the summer months, when the warmth might not be wanted because of the building occupant).
