For the standard size 1.23m x 1.48m, calculations have been done for Double-glazed (D) and Triple-glazed (T) windows which are Operable (O) or Non-operable (N). For operable windows, calculations have been done with two different fittings: Siegenia (Si) or Sobinco (So). Hence, 6 representative products have been calculated for the standard size which corresponds to a surface area of 1.82 m2 . For the large sized windows, i.e. 1.48m x 2.18m, calculations have been done for double-glazed and tripleglazed windows which are operable or non-operable. Only the Sobinco fittings have been modelled for the large operable windows. Hence, 4 representative products have been calculated for the large window size which corresponds to a surface area of 3.23 m2 .
