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)

What’s more, 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.
