I just finished the installation on some Marvin Integrity Windows — which have a fiberglass exterior and a wood interior. They look really good and I’m confident that the fiberglass exterior will hold up over time (although we shall see). I thought that the mounting system was somewhat flimsy, mainly because of the mounting flange. It’s a very thin fiberglass/vinyl material that slides into the slot. I mainly install aluminum windows, which typically use sturdy mounting flanges constructed of aluminum that seem much more solid. Not sure if this is a change in the works for Marvin but I’d be interested to hear more on this. The only other knock I have on the windows is the lack of options available for the Integrity.

We had Integrity Double Hungs put into our home and so far we love them. For the price, we just couldn’t find a window that looked as good on the inside with the wood and had the protection of the fiberglass. I ordered a horizontal slider in the Integrity series but have yet to install it but am excited to see how this one compares. There weren’t lots of choices though, the sales guy said this was one of the reasons for the prices being lower than some of the other fiberglass window options. They pretty much carried stock sizes with a few glass options and no simulated divided lite choices. Oh well — they worked out for us…
