Strong, stable, durable and virtually indestructible, Integrity Ultrex fiberglass 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 Integrity Ultrex fiberglass are obvious.
Integrity pioneered the composite window and door industry 15 years ago with the introduction of Ultrex constructed products. Ultrex’s pultruded fiberglass substrate affords Ultrex superior strength and rigidity. It resists corrosion, is non-conductive, and offers superior heat deflection and thermal expansion and contraction properties that deliver a stronger, more stable and durable window than ever before.
