Fiberglass Window Prices & Costs

Fiberglass window prices run roughly $500 to $1,000 per opening for a normal double hung or casement window with installation. Fiberglass windows are typically 1.5x more expensive than their vinyl counterparts, but less than wood clad windows (although often wood clad uses a fiberglass cladding on the exterior). Fiberglass windows are typically a proprietary composite of some type that offer excellent strength and durability that provide long term value, but obviously are quite expensive at the outset. In general, expect fiberglass windows to run 1.5x more than vinyl windows. Compare vinyl vs. fiberglass windows to see which one is right for you.
