Fiberglass Windows
San Francisco Bay Area

Wood character.
Zero maintenance.

Fiberglass windows are engineered from glass-fiber-reinforced polymer, an extremely strong, thermally stable material that can be textured to look exactly like painted or stained wood. For Bay Area homeowners with Victorian or Craftsman properties, fiberglass offers the best of both worlds.

• Can be painted or stained to match original wood trim and sashes
• Will not rot, warp, crack, or swell, even in coastal fog and humidity
• Superior dimensional stability compared to vinyl in extreme temperature shifts
• Excellent thermal performance, comparable to or better than vinyl
• Ideal for homes in historic districts with design review requirements
• Higher upfront cost than vinyl, lower total cost of ownership over 15+ years

The right window for
historic Bay Area homes

San Francisco's residential character (Victorian flats in the Richmond and Outer Sunset, Edwardian homes in the Mission and Noe Valley, and Craftsman bungalows across the Peninsula) requires windows that respect the original architecture while performing to modern standards.

Fiberglass windows can be fabricated with sash profiles that suit the period, divided lights, and authentic proportions. We regularly work with homeowners in historically sensitive neighborhoods and advise on window selections that will satisfy design review boards while meeting modern energy codes.
