Infinity from Marvin

Ultrex® fiberglass delivers lasting performance

• Expands 87% less than vinyl – resists expanding and contracting in any climate
• 8 times stronger than vinyl – protects the integrity of your home
• Resistant to leaks, seal failures and stress cracks – all things that can affect energy efficiency

Ultrex vs. Vinyl Windows

Vinyl can warp and shift under everyday conditions — potentially making vinyl windows difficult to open and close and affecting their all-around performance. Ultrex resists sticking, swelling and warping so Infinity windows and doors will continue to easily open and close.

Ultrex vs. Wood Windows

Wood windows offer classic beauty that, depending on the environment, can require maintenance and care. Infinity windows capture the beautiful details and profiles of wood – without the maintenance.

Infinity® fiberglass replacement windows were created by Marvin® Windows and Doors, a company which had been recognized as an industry leader in wood windows for nearly a century. This revolutionary line is a durable, attractive, energy-efficient and low-maintenance window replacement option. Composed of an advanced fiberglass material called Ultrex®, Infinity windows also feature EverWood® interiors, a stainable woodgrain finish that looks and feels just like wood yet is completely low-maintenance. EverWood won’t absorb moisture or decay over time; there is no discoloration on the sashes, warping or material degradation – just remarkably reliable performance and lasting beauty.

Infinity Windows includes a growing line of styles, including double-hungs, awnings, casements, gliders, bows and bays, and patio doors that are custom-fit to the exact size of your opening. Callen’s experienced window craftsmen professionally install Infinity windows, resulting in a hassle-free experience for every homeowner.

Infinity Windows: Built for Life™

With Infinity, you can choose windows and doors that offer durability for a lifetime, long-term ease of operation, low maintenance and superior performance. The superior strength of Infinity also allows for a narrower window frame profile and more glass area than other replacement windows, giving you more daylight and better views year after year. Every Infinity from Marvin product is backed by the Infinity Limited Lifetime Warranty.
