WHY MATERIALS MATTER THE MARVIN MATERIALS DIFFERENCE: ULTREX® FIBERGLASS Choosing the right materials for windows and doors is important when it comes to long-term appearance and performance. Ultrex, an innovative fiberglass material pioneered by Marvin over 25 years ago, was one of the first premium composites on the market. However, not all composites are created equal. Some companies use materials with fundamentally different properties and performance values to produce a composite material. Ultrex is different. High-density woven fibers bound by a thermally set resin makes Ultrex more resistant to pressure and temperature than vinyl-based composites. With such different materials grouped in the composites category, it is essential to know what sets them apart. STRENGTH AND STABILITY OF ULTREX Ultrex pultruded fiberglass has a tensile strength 8x stronger than vinyl and 3x stronger than non-fiberglass vinyl/wood composites. Windows and doors made with Ultrex bend and flex less, resist cracking and separating, and stand up better to everyday wear and tear. The exceptional strength and stability of Ultrex eases installation and establishes a secure, long-lasting fit that stays square and true year after year. PULTRUDED FIBERGLASS Thin strands of strong glass cables saturated with compounded resins create a durable material. DURABLE FINISH The proprietary finishing process applies a durable, long-lasting AAMA 624 verified factory finish.

This means seals aren’t as prone to leaking, and windows aren’t subjected to sagging issues like other composites. This is especially true when compared to vinyl, which can distort in extreme heat and crack in fluctuating temperatures. Ultrex resists distortion even at temperatures up to 285°F. Rapid temperature change doesn’t phase Ultrex. From -30°F to 70°F, a 6-foot stile changes less than 1/32 inch in length. EXPANSION MEASUREMENT Ultrex expands and contracts at virtually the same rate as glass. INDUSTRY’S BEST FIBERGLASS FINISH FOR LASTING BEAUTY Ultrex is the first and only fiberglass finish to be verified to AAMA’s 624 voluntary finish specifications for fiber-reinforced thermoset profiles (fiberglass). Windows and doors made with Ultrex resist scratches, dings, and marring more than vinyl. Our proprietary, mechanically bonded acrylic finish is up to three times thicker than painted competitive finishes, and it resists UV degradation up to five times longer than vinyl—even on dark colors.
