Fiberglass widows, are they all the same???

Fiberglass windows have the smallest market in the U.S..

The largest is vinyl by a long shot, and wood is second.

There are only a handful of companies in the U.S. selling fiberglass windows which should make them easier to shop for since you're limited on who you even have out (if you want fiberglass that is).

But here's the problem; just because a fiberglass pultrusion is made in a similar fashion to another, one would think all fiberglass windows are the same (and that's where you'd be wrong).

Stop focusing on just the fiberglass material and (open your eyes and your mind) to all of the other things going into the window.

Like glass packages because the windows going to be 90% glass so why does everyone seem to give all of the focus to just the frame which is only 10% of the window?

Then you what type of spacer is being used, what type of gas fill and how much, how good is the hardware and how's it attached, and then the performance ratings on the whole window.

Yes the whole window (not just the frame).

Yes fiberglass is a great material for many things; but that doesn't mean that all products or windows made out of fiberglass are being built the same or equal in any other way (except the fiberglass material itself.)

The right information takes the guess work out of buying windows
