Milgard C700 Fiberglass Doors

The Milgard C700 is a premium fiberglass door series designed for homeowners who want more than vinyl can offer. Fiberglass is one of the strongest frame materials in the window industry — dimensionally stable across temperature extremes, resistant to warping and corrosion, and built to maintain a tight seal over the long term. Milgard's C700 Series brings those material advantages together with narrow sightlines, energy-efficient glazing, and the aesthetic flexibility to suit new construction and renovation projects alike.

As a certified Milgard dealer, Discount Window and Door supplies and installs the full Milgard C700 lineup throughout Anaheim and Orange County. Contact us for a free estimate.
