I agree. The only recommendation I can give is to get additional quotes on quality products, particularly since one of your requirements is trouble free. While all manufacturers have issues from time to time, some have proven to be better at avoiding issues and then handling the few issues that arise. The list provided by Window1 gives you the three elite manufacturers in the vinyl industry.

My advice would be to first decide on vinyl or wood. Very different products, your individual goals for the project will likely lead you to one or the other. In a nutshell, a high end wood window has the rich look and feel that is unmatched. A premium vinyl window will win on energy efficiency, warranty, and maintenance. I'd avoid low end choices in either material, and unfortunately you don't have much to choose from there in my opinion. If you like wood interiors, look at something like Marvin, Kolbe, or even a fiberglass like Intergrity or Inline. If vinyl is the better fit, Window 1 gave a few good choices.

There are going to be some large divides between the two products between price, performance, and aesthetics. Decide on what the metrics you are going to measure and we will happily point you in the right direction in terms of products. There are, from your cursory list, better options on all fronts.

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)

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?
