Infinity Windows

The finishing touch

Since the 1930's, Marvin has been creating windows and doors of superior quality with a human touch. The company has earned a reputation for fine craftsmanship, using only the best quality materials. Recognizing the need for quality non-wood replacement windows, Marvin has developed Infinity.

Strength and beauty

Infinity windows are made from a pultruded fiberglass called Ultrex. Compared to other types of windows, Ultrex is superior in virtually every category. More than 8-times stronger than vinyl, Ultrex is made with strong cables of glass that are saturated with specially compounded resins. This makes Ultrex durable, non-corrosive, and virtually maintenance-free. The Ultrex in-line patented coating process provides a thick, hard coating that resists corrosion and keeps windows looking great for years. The superior strength of Ultrex allows the window frame profile to be narrower that those made of vinyl or wood, giving you more visible glass area. From scorching summer heat to freezing winter temperatures, wherever you live, Ultrex is built to perform. No matter how extreme the temperature, Ultrex remains square and true.
