The Uw values given below refer to the sample size. The sample size refers to a single-sash window with a width of 1230mm and a height of 1480mm. All Uw values from German manufacturers are determined using this window size. As the window gets smaller, the Uw value goes down accordingly. For larger windows, the Uw value generally improves. Please note that the warm edge (thermally separated edge seal) is required to receive funding from the KfW (Reconstruction Loan Corporation). The Uw-values specified also apply to Smart-Slide sliding doors. Since their dimensions are larger than those of a test size window, however, Smart-Slide sliding doors achieve better Uw-values overall.
