How Strong Are Infinity from Marvin Fiberglass Replacement Windows?
Watch for yourself!
Infinity uses fiberglass for unmatched performance. But that’s only the beginning.
Replacement windows have always been Infinity's sole focus. And that means they pioneered the use of materials like fiberglass that outperform and outlast other options. However, Infinity goes even further with Ultrex® — our proprietary fiberglass solution that offers unsurpassed durability and timeless style.
How Ultrex fiberglass measures up
Infinity created Ultrex® with one goal in mind: develop the most durable window material in the industry. It’s not only eight 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 common conditions — potentially making vinyl windows challenging 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 support.
