I posted earlier about how we are having all of our windows redone with complete installs (down to the studs). At the time of that posting, I was considering Vinyl and Fibrex. From the education I've been receiving, I'm now intrigued by fiberglass. Sounds like lots of people recommend Marvin windows that are fiberglass. Why is this a better choice than vinyl and do fiberglass windows have as many options to make the interior match a wood grain?
