Infinity Windows

Since the late 1930s, 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 quality materials to build windows and doors that are beautiful and long-lasting. Recognizing a need for non-wood replacement windows for discerning homeowners like you, Marvin presents Infinity, a revolutionary line of exceptional products from an industry leader.

Attractive, durable, virtually maintenance free and professionally installed, Infinity windows are made (inside and out) with Ultrex - a pultruded fiberglass material that outperforms and outlasts all other window materials.

Made with strong cables of glass that are saturated with specially compounded resins, Ultrex is durable, non-corrosive, has low thermal conductivity, and is virtually maintenance free. The superior strength of Ultrex allows the window frame profile to be narrower than those with frames made of vinyl or wood, giving you more visible glass area. And no matter how extreme the temperatures get, Ultrex stays square and true.

Once Infinity windows are installed, there is virtually nothing left for you to do except enjoy the view - you never need to sand, scrape or paint Ultrex.
