Albuquerque factors
Our days can swing 30 degrees or more from morning to afternoon, and west walls get intense sun. Fiberglass shrugs off that movement. Quality vinyl handles it fine in white and light colors, which is why it's the most common replacement window in town.
Bottom line
- Standard sizes, light colors, budget in mind: vinyl
- Large windows, dark colors, west walls, long-term: fiberglass
- Many homes mix them — fiberglass for the big view windows, vinyl elsewhere

Common questions
Does fiberglass save more energy than vinyl?
Frame material matters less than glass. With similar glass, they perform similarly.
Can I mix vinyl and fiberglass in one house?
Yes. Matching colors closely across materials takes some planning.
