If you're shopping around for new windows, you may be overwhelmed by all the options available. Should you choose wood or vinyl frames? Double-pane or triple-pane glass? Single-hung or double-hung windows?

If choosing a strong, durable window that can stand the test of time is at the top of your list, we can't recommend Infinity from Marvin fiberglass windows enough. However, before you can understand why these windows are so valuable, you need to learn more about the material they're made from—Ultrex®!

What Is Ultrex Fiberglass?

Ultrex is a pultruded fiberglass product patented by Marvin. Marvin creates Ultrex by saturating strong glass cables with specialty compounded resins, pulling the glass cables through a heated dye and cutting them with diamond-edge blades. The result? Fiberglass windows that are stronger and more maintenance-free than vinyl, wood, or any other window material on the market.

Let's look at the valuable benefits of Ultrex fiberglass and how the strength of this material stacks up against vinyl and vinyl/wood composite windows:

Unique Benefits of Ultrex Fiberglass (Compared to Vinyl & Vinyl/Wood Composites)

Exceptional Strength

As we mentioned above, Ultrex fiberglass is so strong it requires a diamond-edge blade to cut through it! Ultrex is the most durable framing material in the window replacement industry, designed to resist warping and weathering so that it won't bend or flex. In fact, Ultrex is eight times stronger than vinyl, three times stronger than wood and vinyl composite products, like Fibrex®, and even more robust than other fiberglass window materials on the market.

Expanded Views

The strength of Ultrex doesn't just impact the longevity of your windows—it affects your views from your home, too. Since Ultrex is such a durable material, Infinity from Marvin actually uses less of it when making their fiberglass windows. This means you get thin, elegant frames, especially in comparison to other replacement windows, allowing you to enjoy bright, expansive views and more natural sunlight in your home.

Energy Efficiency

If you live in a climate with drastic changes in temperature or humidity, you won't have to worry about seal failures and air leaks that compromise your window's performance with Infinity from Marvin windows. Ultrex expands at nearly the same rate as glass. In addition, Infinity from Marvin windows (made with Ultrex) with Low-E glazing can help reduce your yearly heating and cooling costs.

Effortless Beauty

Ultrex may make your windows durable, but that doesn't mean they can't be beautiful. Infinity from Marvin fiberglass windows come in a variety of interior and exterior colors, including Stone White, Sierra, Ebony (Black), Bronze, and more! No matter what color you choose, Ultrex uses an acrylic finish three times thicker than the competition to resist scratching, denting, chalking, or fading. Infinity from Marvin also has an engineered woodgrain interior finish- called EverWood® - that looks, feels, paints, and stains like wood but is entirely low maintenance.
