What Vinyl Does Well, And Where It Starts To Show Limits

Vinyl is still the lower-cost choice for many projects. It is easy to source, familiar to installers, and usually priced below fiberglass in most markets.

That lower price is a real advantage on a whole-house project. If you are replacing a large number of openings, the difference can free up money for upgraded glass, better screens, or professional installation.

Fiberglass Windows: Durability, Stability, And Long-Term Value
