Experience with Fiberglass Windows
I am interested in anyone's experience with fiberglass windows. Do they have a failure rate equal to the good vinyl windows? I like the idea that there is more glass in each window and they don't expand/contract like vinyl hopefully insuring a better window seal. The guarantee does not seem to be as long as the vinyl, 20 yrs vs "lifetime". Milguard, Marvin are 2 names that I have run across. Are there any other quality names I should be looking at. One question I have, if they are soooo good, why only the 20 yr warranty vs lifetime for vinyl?
