Vinyl vs. Fiberglass vs. Wood vs. Aluminum: Which Window Material Is Best?
Cost from lowest to highest
Aluminum and vinyl are the most affordable frames, followed by fiberglass, with wood and wood-clad at the top. Vinyl averages about $558 per window installed; fiberglass commonly $500-$1,600; wood $700-$2,000; aluminum $397-$846.
Durability and maintenance
Fiberglass and wood-clad last the longest (40+ years) and fiberglass is the most dimensionally stable. Vinyl is low-maintenance but cannot be repainted. Aluminum is strong but conducts heat and needs a thermal break.
How to choose
Pick vinyl for best value, fiberglass for durability in extreme climates, wood for a premium traditional look, and thermally-broken aluminum only for modern designs or mild climates. Nearly 85% of homeowners choose double-pane glass regardless of frame.
