Fiberglass Windows & Doors

Milgard Ultra Series C650 fiberglass custom windows are heat and cold resistant, durable and low-maintenance. The frame expands and contracts at approximately the same rate as the insulated glass it holds, putting less stress on the seals for a clear view.

Ultra Series windows and patio doors have fiberglass frames inside and out with four exterior colors available. Each exterior color can be paired with a white interior. However, you can color-match both the interior and exterior colors in Harmony, Bark or the popular Black Bean. A wide variety of grid types, patterns, and combinations are also offered.
