fiberframe replacement fiberglass windows

Sunroom Features - Windows

Fiberframe fiberglass sunrooms are made with Fiberframe’s ENERGY STAR rated windows and doors, making them highly energy efficient.

You’ll see and feel the difference as you enjoy your new space, benefited by the same Cardinal glass that we use in all of our products:
  • Lower total energy transmitted for cooler rooms in the summer and warmer rooms in the winter.
  • Provides protection from sun fading of interior furnishings, carpets, and fabrics.
  • Meets or exceeds ENERGY STAR qualification when you include argon gas in your specifications.
  • Lower U-values (low is better) than standard insulating glass.
  • Tempered glass is standard on all doors and windows
