The Infinity Difference

Infinity® replacement windows and doors are made from Ultrex fiberglass material so strong and durable it is superior to other window materials. Best of all, it makes Infinity products virtually maintenance free.

Advantages of Ultrex® Fiberglass

Strong, stable, durable and virtually indestructible, Ultrex is possibly the perfect material, creating windows and doors that leave other materials in the dust.

  • Patented mechanically bonded acrylic cap, virtually indestructible surface.
  • 8x stronger than vinyl, 3.5x stronger than wood.
  • 500x less thermal conductivity than aluminum.
  • Low thermal expansion (essentially the same as glass) for better seals, longer life.
  • Strength allows for narrow better looking profiles and more visible glass area.
