Fiberglass Windows by Milgard

When you first look at Milgard fiberglass windows in San Francisco, you might think you’re looking at an all-wood window. That’s no coincidence. Our fiberglass windows and replacement fiberglass windows are designed to match the beauty and profile of solid wood windows, while providing the strength, durability and performance of fiberglass windows. Milgard’s own fiberglass production process enables us to make the complex profiles required for the look of painted wood windows on some San Francisco home exteriors, with the option of choosing fiberglass or natural wood for the interior. Our process also allows us to engineer superior fiberglass windows that are impervious to water, cold, heat, insects, salt air and ultraviolet rays. Add to that our Lifetime Warranty with Glass Breakage and you have energy-efficient fiberglass windows that maintain their beauty in the harsh San Francisco environment.
