Infinity windows are made from Ultrex, inside and out. This fiberglass material is so durable, so long lasting, so strong, you’ll never have to worry about replacement windows again. Best of all, it makes Infinity windows essentially maintenance free.

The Ultimate Material for Replacement Windows

Made of pultruded fiberglass – thin, strong cables of glass, saturated with specially compounded resins -Ultrex is a remarkably durable material that outlasts and outperforms other window materials. What makes Ultrex clearly superior?

  • It is 8x stronger than vinyl, 3.5x stronger than wood composites and 3x stronger than wood.
  • Less thermal conductibility than aluminum (500x less), which means Ultrex doesn’t conduct heat or cold from the outside into your home.
  • Low thermal expansion rate (essentially the same rate as glass) means less material movement for better seals and longer endurance.
  • Won’t discolor, warp, rot, corrode, dent, rust and never needs sanding, scraping or painting.
  • Strength allows for narrow window frame profile for more visible glass area
