Why Choose Vinyl when Fiberglass is the Best?


  • Maintenance - Don't need to re-stain and can match any style, even wood!
  • Strength - Fiberglass is 8 times stronger than vinyl windows
  • Materials- Thinner frame so you won't lose any glass space!
  • Stability - Great at insulating for energy and noise control
  • Quality - Highest quality window in the market that lasts up to 50 years
  • Added Bonus: Lifetime Warranty


  • Maintenance - Vinyl can warp in heat, but can handle rapid temperature fluctuations
  • Strength - Easy to install and don't require consistent painting
  • Materials - While you can see "scar marks", vinyl is a more affordable option
  • Stability - Expands and contracts at higher rates, but generally long-lasting
