Durable doesn’t begin to describe how tough Ultrex is. Strong, stable, and virtually indestructible, Ultrex is quite possibly the perfect building material, creating windows and doors that leave other materials in the dust.
Made from pultruded fiberglass, Ultrex outperforms the competition on nearly every measure. Non-conductive and non-corrosive, Ultrex resists the ravages of heat, cold, time and pressure to provide the most worry-free windows and doors available today.
Pioneered by Marvin ® , Ultrex has what it takes — from its durability and performance characteristics, to its first-to-market ingenuity — to create products of incomparable value.
Low-maintenance and high-durability. Everything you want your home to be, and everything that Ultrex delivers.
Temperatures may fluctuate, but Ultrex ® won’t.
Ultrex has an extremely low rate of thermal contraction and expansion. In fact, it expands and contracts at virtually the same miniscule amount as glass, maintaining a tight seal with no leaks, seal failures or stress cracks that can compromise energy-efficiency and long-term performance.
This is especially so when compared to vinyl, which can distort in extreme heat and crack in fluctuating temperatures. But Integrity ® windows and doors can withstand temperature extremes while maintaining a tight seal.
Designed for beauty. Engineered for life.
Our 20+ years of experience in the composite fenestration industry led us to ensure that every part is optimized for the ultimate in performance and fit, including detailed radius profiles and clean, balanced sightlines. Windows and doors made with Ultrex won’t get scratched, dinged or marred as easily as vinyl. Our patented, mechanically bonded acrylic finish is up to three times thicker than competitive finishes, and it resists UV degradation up to five times longer than vinyl — even on dark colors.
3x less expansion than wood/vinyl composites.
Ultrex resists distortion even at temperatures up to 285°F. Rapid temperature change doesn’t faze Ultrex: When the mercury climbs from -30°F to 70°F, a 6′ stile changes less than 1 / 32 ” in length.
Ultrex ® also stands up mightily to rain, wind, heat and time, looking beautiful and performing well long after other window and door materials have lost their luster.
The strength of Ultrex also translates into superior stability. Ultrex is more rigid than vinyl and vinyl/wood composites. So issues of instability and less-than-perfect alignment that can complicate installation — and long-term performance — are not a concern with Integrity ® windows and doors
The exceptional strength and stability of Ultrex eases installation and establishes a secure, long-lasting fit that stays square and true even under the most punishing conditions.
Built to Perform ®.
It’s more than our tagline, it is our promise to you. Ultrex is so resilient, it outperforms and outlasts vinyl and vinyl/wood composites, time and time again. Strong yet light, Ultrex provides sturdy, reliable support from top to bottom, end to end.
Integrity windows have a clean glazing bead profile and have solid, square, weathertight
joints. Vinyl corners can arrive with messy welded corners and joints that aren’t square.
With a finish up to 3x thicker than competitive finishes Integrity products won’t dent, crack, chip, or peel. Its unmatched detailed profiles and superior tooling capabilities provide for a cleaner fit and finish.
Integrity windows use a patented, mechanically bonded finish, shown on the left, compared
to the competitive finishes that are painted on and can be unsightly.
Eighty years of innovation and uncompromising product performance standards: that’s the legacy of Marvin Windows and Doors. And it’s why we build energy efficiency into every Integrity ® from Marvin product.
A history of integrity.
Marvin has a long history of product innovations, industry firsts and commitment to community. Integrity Windows and Doors takes pride in the fact that our corporation is green-minded with recycling efforts and employee awareness. In addition, we incorporate green components into our product packaging and even our distribution process.
Beyond that, being green is also about conserving energy — and Integrity is energy efficient. Not only are the products extremely durable, Integrity from Marvin was the first major window and door manufacturer to offer its ultra durable Ultrex ® energy-efficient Low E2 insulated glass with Argon and ENERGY STAR ® qualified performance on all of its standard windows and doors.
Today, Marvin is credited with several industry firsts and is recognized for innovative products
and uncompromising product performance standards. Third- and fourth-generation Marvin family members remain actively involved in the company and keep the original spirit of corporate responsibility alive today.
Superior performance you can feel good about.

- The Ultrex manufacturing facility fully complies with the 1990 Clean Air Act and has been designated as a Maximum Achievable Control Technology (MACT) facility as outlined by the Environmental Protection Agency (EPA).
- The glass in our products contains 15%–33% recycled content.
- Integrity products offer ENERGY STAR qualified performance.
- Even more green awards and information at integritywindows.com.
Stellar energy performance ratings.
The NFRC defined an energy performance rating system for the entire window and door industry. It rates:
- U-factor, or how well a window keeps heat inside a building.
- Solar heat gain, or a window’s ability to block warming caused by sunlight.
- Visible light transmittance, or how much light gets through a product.
- Air leakage or heat loss and gain by infiltration through cracks in the window assembly.
Fortunately, Ultrex is far less conductive than aluminum and is similar to wood and to PVC. It provides an insulated barrier against extreme weather temperatures, keeping homes comfortable, and reducing heating and cooling costs.
The National Fenestration Rating Council, the Department of Energy, and the U.S. Environmental Protection Agency were all
impressed, so much so that Integrity ® Windows and Doors received one of the highest performance ratings.
