Ultrex is as strong as low carbon steel and is up to 8 times stronger than vinyl – in fact, it’s so tough we need to use diamond-edge blades just to cut it to size. The strength of Ultrex means superior stability, long-term ease of operation, low maintenance, and superior performance.

Strength for an expanded view

Our patented process begins with strong glass cables saturated with specially compounded resins which are then pulled through a heated die before being cut with diamond-edge blades. You can see below the steps that Ultrex goes through, from forming and curing all the way up to cutting. These steps help ensure the creation of a remarkably durable material able to outlast and outperform other materials used for windows.

The low expansion of Ultrex means Infinity Windows resist sticking, swelling, and warping, providing easy operation for the life of the window.

The low expansion means Infinity’s patented finish looks like new for a very long time. It’s practically maintenance-free because it resists discoloration, warping, rotting, corrosion, denting, and rust. It also doesn’t require sanding, scraping, or painting.

Our patented, mechanically bonded finish is up to 3x thicker than that of the competition, providing superior resistance to scratching and UV degradation even on darker colors. The Ultrex coating system is AAMA 624-10 verified. That is, our commercial-grade finish resists even the harshest weather conditions that Mother Nature has at her disposal – a claim many competitors can’t match.
