Good Day, Wondering if anyone has any opinions on Farley 7000 casement windows vs. Okna 700 casement windows. The estimates I have are reasonably equivalent, as is the numerical performance. Edge to Farley for a lower SHGC with low-e 366, slight edge to Okna for U-Value. Farley: www.farleywindows.com Okna: www.oknawindows.com I can also get the Okna in a triple pane (double argon fill) for $55 per window section upcharge. Worth it? Sean.
