Many Choices

Fiberglass windows are environmentally friendly. In addition to their energy-efficient thermal performance, fiberglass windows are manufactured using highly sustainable materials (like sand), arguably making fiberglass one of the greenest window choices available.


Fiberglass Window Replacement Benefits


Why choose fiberglass replacement windows over vinyl, wood, or aluminum windows? Here are some reasons:

  • Highest material strength and durability

  • Excellent energy efficiency

  • Extremely resistant to warping caused by heat or moisture

  • Wide range of styles, including woodclad finishes

  • Easy to paint (if desired)

Generally more expensive than windows and doors made out of vinyl or aluminum, fiberglass windows and patio doors can be a better value over time. Their attractiveness adds greater value to your home than these other window materials. Equally important, their durability and long life enable them to hold value for years.

Fiberglass is impervious to water, cold, heat, insects, salt air and ultraviolet rays—all the traditional enemies of windows and doors. Unlike wood, fiberglass frames won't crack from dryness, swell, peel or warp. What's more, because fiberglass frames are essentially glass fibers and resin, the frames expand and contract very little and at approximately the same rate as glass. This puts less stress on the seals and increases their life and effectiveness.

Fiberglass also is popular because, just like a wood window frame, you can paint it. But there is one important difference—you don't need to treat a fiberglass frame with toxic preservatives to prevent rot and decay, and it won't deteriorate if the paint gets scraped off or otherwise damaged.

Fiberglass frames are popular because a wood veneer can be added to the interior. This gives you the best of both worlds: the durability of a fiberglass frame exterior and the warmth and beauty of a wood interior.
