Infinity from Marvin Windows | Why is Ultrex Fiberglass the Best Replacement Window?

How does Ultrex® fiberglass compare to other window materials?

Ultrex vs. Vinyl

Ultrex is 8x stronger than vinyl, which means you get narrow frames that brighten your home with more daylight and bigger views compared to vinyl. Additionally, vinyl can warp and shift over time, making windows difficult to operate and affecting their overall performance. Ultrex resists sticking, swelling, and warping, ensuring that Infinity windows remain easy to open and close.

Ultrex vs. Wood

Wood windows provide classic beauty but often require ongoing maintenance depending on the environment, as well as potential rot issues. Infinity windows offer the same beautiful details and profiles of wood—without the upkeep. Additionally, although Infinity windows do not require any painting, they can be painted any color or stained on the interior.

Ultrex vs. Other Composites

The Ultrex fiberglass frame is highly stable, expanding at nearly the same rate as the glass. In contrast, vinyl and wood/vinyl composites expand over twice as much as glass, which can affect energy efficiency and performance. Ultrex is also 3x stronger than wood/vinyl composites.

How to Know When You Need New Windows?

The lifespan of your windows depends on various factors, including the frame materials, installation quality, and your local climate. But how can you tell when it's time to replace them?

High Energy Bills

If your energy bills are rising or you feel drafts near your windows, it might indicate that your windows are no longer insulating your home well. Modern windows often include advanced insulation technologies like double or triple glazing, low-emissivity (Low-E) coatings, and gas fills between panes, which enhance energy efficiency.

Noticeable Wear & Tear

Cracked or rotting frames, peeling paint, and warped window sashes are signs that your windows are no longer performing properly. These issues can affect both the functionality and the aesthetics and safety of your home.

Hard to Operate

Windows that are hard to open, close, or lock can be both frustrating and unsafe. Modern windows offer user-friendly features such as easy-to-use locks, smooth operation, and even motorized options.

Not Your Style?

Sometimes, you simply want an updated look to match your aesthetic or elevate your curb appeal. Infinity from Marvin's fiberglass windows have a timeless look that will bring new life to your home.

Protect your home and family from stuck, leaking, and rotting windows, all while improving the look and energy efficiency of your home with our beautiful fiberglass replacement windows. Call Now!
