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.
