Ultrex® pultruded fiberglass, an innovative material Marvin® created over 20 years ago, was one of the first premium composites on the market. Highly durable, strong as steel, and extremely reliable, Ultrex performs as well years after installation as it does on day one. Now, you can have Bronze and Ebony interior finishes on All Ultrex windows, maintaining the strength and durability of Ultrex with finishes relevant to today’s design trends.

Through our partnership, more than 50 handcrafted Marvin windows will be installed during this season’s ambitious update of the Arlington House, an early English-style Arts and Crafts home built in 1909 in Arlington, Mass. As the project unfolds, the beloved “This Old House” cast – Kevin O’Connor, Norm Abram, Roger Cook, Richard Trethewey and Tom Silva – walks viewers through an extensive renovation and remodel using carefully selected materials and products, like the Marvin Next Generation Ultimate Double Hung window, honoring the history of the home while incorporating modern design touches and amenities.
