Factory Authorized Dealer & InstallerA premium look that's worth understanding before you buy. Here's what fiberglass offers, how it compares, and the lines we install across the Bay Area.
Fiberglass barely expands or contracts, takes paint beautifully, and lasts for decades — the choice when you want maximum strength and stability.
An honest look at where fiberglass fits among the four materials.
| Wood | Vinyl | Fiberglassyou're here | Aluminum | |
|---|---|---|---|---|
| Look | Warmest, most classic | Clean & simple | Sleek, paintable | Slim & modern |
| Maintenance | Low (clad) to moderate | None | Very low | Low |
| Energy efficiency | Excellent | Very good | Excellent | Good (thermal break) |
| Cost | Premium | Best value | Mid–high | Mid |
| Lifespan | Decades, with care | 20–40 years | Very long | Very long |
We fit premium fiberglass lines from these makers — Marvin Signature is the best on the market.
If you want maximum strength, stability and lifespan, yes — and it can be painted.
Both are efficient with Low-E glass; fiberglass holds its shape better over time, keeping seals tight longer. When you compare, look at the ENERGY STAR rating and the NFRC label.
Fiberglass sits between vinyl and wood on price. We give a free written in-home estimate. There is financing if you would rather spread it out.
