We are hoping to break ground in the next few weeks and need to select windows. Builder priced in Andersen 400. We will have 4-panel slider, and mix of casements and double hungs. We are outside Chicago area so do have windy cold winters. I find the TW feature on the 400 hard to operate. And the vinyl interior jamb is unsightly. Is there a big performance difference between the 400 and the A series? We don’t want to worry about drafts coming thru the windows in the winter! We have also looked at Marvin Elevate but have heard some issues lately with quality control. Any feedback would be appreciated.
