Thank you all of you for your recommendations. We are building our home in New Albany OH (east of Columbus). The price comparison between wood vs vinyl is roughly $31k vs $16k. Cost is a moderate factor so Vinyl or non wood windows is definitely an option. Since the interior is going to be painted solid color (off white), I think vinyl or PVC should be ok. When it comes to vinyl, some dealers said that they cannot mull some of the large windows vertically, and I have to make changes to the window sizes and layout in the plan. Out of Anderson/Silverline, Windsor and Quaker (all vinyl windows), only Quaker can actually match our design requirements. Just for clarity, here are the window schedule. (This schedule is only for sizing) https://drive.google.com/file/d/0BxbJ91RIbyqMT2FtWmgwVjdsbmM/view?usp=sharing The main concern I have with Quaker Manchester series is that their DP rating is from 50 to 15 for the larger ones. Also, they only offer 20 year warranty, glass only 1-2 years for stress cracks. Have you had any experience with Quaker Manchester series? MP

With all due respect @jesjonesy, I was the first one to direct you to the European style operators in post one. I was challenging the idea that someone was putting forth that you can only source a quality window from Europe. That simply is not true and the assertion that US built windows are a "bag phone" vs. and iphone is laughable. Some of the most trend setting development in glazing is happening right here in this country. Again...if you are looking for a European style operator (i.e. push out casement) you sources West of the Rockies will be limited and even more so in vinyl. If you are willing to entertain fiberglass or wood, you can expand your search. There are some very good manufacturers in North America that make some products in fiberglass that will at least equal the performance of the European units cited in thermal, structural, and air infiltration performance. The other mention of glazing is, for lack of a better descriptor, a bit of hooey. Cardinal has been meeting Euro-spec gas leakage rates for the last 10+ years and provides a lifetime warranty on their units. The most likely thing to fail on a sealed and insulated unit is going to be the glass. That potential probably goes up by a measure percentage the more it is handled and shipped across the globe. I don't know about you, but I would want to be able to warranty my glass with a product that is made here in the states and easily accessible without having to cross the Atlantic. If someone can show me a performance metric in a window from Europe that doesn't have a competitive equivalent here in the states and it was desirable, I might be inclined, but I haven't seen something produced over there that is unable to be sourced in North America.

+1. Those are large windows, so quality will be a big deal regardless, and casements can be hazardous on a deck unless its large and the flow can be arranged to minimize that impact. You might consider a transom over the units to make the height more manageable. A 72" casement may sag after a while, and a 72" slider may rock when operated.

I just received 8 large 100series Andersen windows to be installed in my sunroom. My builder found one cracked and said the others were cheaply made and he didn’t feel right putting them in as cheaply made as they are. So....... we are sending them back and now I have to wait another 12 weeks or more for another set of windows to be made somewhere else. They DEFINITELY won’t be Andersen windows. Very disappointing!
