Strong, stable, durable and virtually indestructible, Ultrex is possibly the perfect building material, creating windows and doors that leave other materials in the dust. If you’ve ever encountered a dented or corroded roll-form aluminum window or a faded, cracked vinyl window, the advantages of Ultrex are obvious. Ultrex’s specially compounded resins and thin strands of strong glass are combined to create a material so strong, it’s used in bridge construction; so stable, it remains virtually unchanged even when it’s subjected to extremes such as temperatures ranging from -30°F to 350°F.

Windows made with Ultrex components expand and contract at the virtually same minute rate as glass, so each window remains tightly sealed with no leaks, seal failures or stress cracks. It’s so strong, we have to use diamond-edge blades to cut the pieces to size. Imagine what that level of durability can endure in your home.
