I think your GC is a little off. We just did a high end house with Integrity/Wood. Unless they have changed recently, the Ultrex/Wood looks a lot nicer on the outside also. See the link below to our house. The Wood/Ultrex turned out really well. These pics are at the end of construction, they look even better now. I have had these for a little over a year now and am very pleased with them. Our builder leaned towards "cheaper" windows also (he preferred WIndsor). To me, Windows are one of the most important aspects of construction. You are talking $5k or so on an $800k house. Don't scrimp on windows, doors or plumbing fixtures.

Follow up on my Marvin Integrity Ultrex Fiberglass windows. First let me say that not one person from my local dealer or from Marvin ever came to look at these windows. Maybe they just don't do that? I asked Marvin to do one of three things, Pay me to fix the problem. Send someone to fix the problem or replace the 14 windows. Marvin decided to replace them all but offered no help in swapping them out. I was told that the shrink wrap machine would be adjusted so as not to warp the extended jambs. The replacement windows arrived and upon inspection of a few they were warped. As time allowed I looked at more and the amount of work to straighten them would be no different than the already installed windows. The windows were picked up yesterday by the dealer. I am now left to make a 2X4 frame for each size to hold the jamb out while I foam the insulation around it. I will set the frames aside and after the sheet rock is in use the frames again to hold the jamb in place while I install the trim. I have also found that some of the sills are bowed up (from nylon straps in shipping) causing the window to lock very hard. Pulled the bottom nails and clamped it down and re nailed it, helped some. It's a mess in that as I am doing an owner/builder and it eats up my time. I haven't heard anything from Marvin about compensation but at this point I need to move ahead with the project. Projected CO date Oct 6th of this year!

In my opinion, the Marvin Integrity that is all ultrex in and out is just plain ugly and cheap looking. The Infinity is a much nicer looking window. I also remember a Marvin rep telling me a few years back that Infinity utilized a thicker guage fiberglass and it was built better. The jamb on the integrity is very narrow and not 3 1/4 like most replacement windows. I do not like the Integrity ultrex at all.

I have been in the market for windows for the last year or so looking over my options and pretty much narrowed it down to the Marvin Integrity All-Ultrex and the Andersen 100series. I currently have aluminum clad wood casement windows which are original from 1986, and are replacing with casements. I have total of 12 windows (5 of which are mulled, and 7 singles) as well as a sliding patio door. All of our current windows have rotting wood, some sashes under the aluminum clad totally or partially gone, paint faded off the aluminum, gaskets between aluminum and glass are shot and a lot of hardware failure, mainly do to rotted wood. We live in Southwest Pennsylvania so we see cold winters, hot summers and your typical day/night temperature swings. We are looking for a casement window that's easy to clean, low maintenance, must have a white interior and a contemporary look. We have pretty much narrowed it down to the Andersen 100 series and the Marvin All-ultrex, both of these fit what we are looking for. We are trying to steer away from clad wood for those reasons stated from before and the fact we want a white interior and we don't like the look of the pure vinyl. I was pretty much sold on the Integrity All-Ultrex, however with the lack of a custom sized sliding patio door started to make me look else where, and I was not completely fond of the somewhat flimsy widow stops, but it could be over looked. So I happened to come across the Andersen 100 series Fibrex which look very similar and in some respects look better as well and looking at the architectural details look sturdy and well built, only questionable is the piece that holds the glass on the exterior side, where as it's a one piece on the Marvin. 100 series Ultrex Performance number are pretty close to the same for both as well. The glass package to my knowledge is the same Cardinal glass and in both cases looking at the Low E 272. In either case we would be finishing off the interior trim in a composite material as well. I guess I am just looking for some feedback on these two windows, if anyone has considered the two, also in terms of durability, performance, longevity, overall fit and finish and how happy you are with the windows. As well as what made you decide on the window. Lastly if any installers have feedback on these as I will be installing these myself with a nailing fin as I am replacing my siding at the same time. Thank you!
