Vinyl vs. Fiberglass vs. Aluminum Windows
Quick Answer
Vinyl is typically the most accessible and low-maintenance choice. Fiberglass adds structural strength, paintability, and dimensional stability at a higher price point. Aluminum offers the slimmest frames and largest glass area, favored for contemporary architecture. There's no universal "best" — it depends on your priorities.
