What makes fiberglass different
Fiberglass frames are made from glass fibers set in resin. The material expands and contracts at close to the same rate as the glass it holds, so seals stay tighter through the big day-to-night temperature swings we get in the high desert. It's also strong enough for narrower frames, which means more glass and more view.
Good fits for fiberglass
- Large picture windows facing the Sandias or the volcanoes
- Dark bronze or black exteriors on stucco homes
- West-facing walls that bake every afternoon
- Homeowners who want a long-term window and don't mind paying more up front

Common questions
Is fiberglass better than vinyl?
It's stronger and handles dark colors and big sizes better. Vinyl costs less and performs well for most standard windows. Many homes are a good fit for either.
Can fiberglass be painted?
Many fiberglass frames can be repainted later, which vinyl generally can't. Check the maker's guidance first.
