You're correct; I misspoke. I should have said "composite" window. The Andersens are made from a composite product called Fibrex, which is basically wood mixed with a resin-type material. From what I've read, it isn't as strong as the Ultrex fiberglass that Marvin uses, but I'm not sure if the Ultrex is $8500 more impressive. We don't want to go with the 400s because we don't want the maintenance with the wood portions of the windows. I looked over the two quotes closely this morning. The substantial difference is in the fixed glass (solid single pane) picture windows. The Integrity windows are more than double the price of the 100s for these fixed windows. For casements and other opening windows, the prices were not substantially different. I guess I'm not sure why these fixed windows are more than double the price? Thoughts??

We ended up going with the Integrity windows. I am happy with the look and quality of the windows (with the exception of the locking lever on casements, which has a cheap plastic cover rather than being solid metal). Two cautionary points: they delivered very late (like 50-75% longer than quoted) and I had to make some compromises to fit within Integrity's limited size options (had to use two awnings over a set of French doors because they couldn't make a single one wide enough). I suppose the late delivery could have also happened with the E-series, but my understanding is that the E-series has extensive size options. As for the durability I'll need to wait and see, but on balance I am happy with my choice.

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!

That’s not accurate LD, Todd is right. The amount of glass lost can vary substantially depending on what’s being removed as well as the product being installed. In some cases no glass Is lost even on a replacement, but that’s rare. The 1-1.5” loss is probably a fair average overall, but again, lots af variables and casement vs hung is not a main factor
