Fiberglass is one of the strongest and most energy-efficient frame materials available. It resists swelling, rotting, warping, peeling, pitting, and corrosion, making C700 windows durable and low-maintenance in any climate.
C700 Fiberglass Series windows and patio doors have fiberglass frames inside and out with six exterior colors available: White, Black, Bronze, Bark, Adobe, and Steel Gray. Each exterior color can be paired with a white or color-matched interior.
Milgard tests every C700 fiberglass frame for color uniformity, gloss, film thickness, and chemical resistance. The result is a durable, long-lasting finish that resists peeling, warping, splitting, pitting, and corrosion -- even in coastal, desert, and high-altitude climates.
The C700 Series offers flat grids and sculptured grids placed between the glass for easy cleaning, plus simulated divided lites (SDL) and check rails for a more traditional appearance. Grid colors match your exterior frame color.
The C700 Fiberglass Series comes standard with Milgard's Lifetime Limited Warranty. Painted and powder coat finishes are covered for 10 years against excessive peeling, cracking, chalking, fading, or color change. A Full Lifetime Warranty is also available as an optional upgrade at the time of purchase. See milgard.com/warranty for complete details.
