MATERIALS MATTER

Ultrex fiberglass for unmatched performance

We created Ultrex with one goal in mind: develop the most durable window material in the industry. It’s not only 8 times stronger than vinyl — it resists expanding and contracting in any climate. So you get a tight, snug fit that will last.

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.

Fade-Resistant Finish

Want long-term color retention? Ultrex uses an acrylic finish that is fade-resistant and virtually maintenance-free.

With a finish that’s 3 times thicker than competitive options, Ultrex resists chipping, denting or peeling.

More View for Your Money

Because Ultrex is so strong, we actually use less of it in Infinity window frames. That means you get more daylight coming through your window, without bulky materials obstructing your view.

EverWood Beauty and Texture

EverWood^®, our breakthrough engineered wood grain interior finish, offers natural looks and textures – plus the durability you demand. It looks, feels, paints and stains like wood but is completely low maintenance.

See how Ultrex stacks up

Because of Ultrex’s incredible strength, we can build narrower frames — so you get more incredible views for your money. But that’s just one example of where Ultrex fiberglass truly exceeds expectations.

Specifically designed to resist warping and weathering in any conditions for long-lasting durability.

VS.

Vinyl

Can shift up to 1/4” under everyday conditions— potentially compromising your home’s integrity.

Stands up to the pressure

Compared to other materials, Ultrex is the strongest window framing material in the replacement industry. That means Ultrex resists bending and flexing – that’s confidence Fibrex^® and vinyl simply can’t match.

A fit that never quits

Ultrex expands at virtually the same rate as glass, so our windows stay tight and true. This makes Infinity windows resistant to leaks, seal failures and stress cracks that can compromise energy efficiency and long-term performance.

Ultrex is stable like the glass in your window

Vinyl expands at a much higher rate than glass which may compromise your window’s performance.
