Ultrex Fiberglass outperforms Vinyl & Wood

Marvin created Ultrex with one goal - develop the most durable window material in the industry. It's not only 8x stronger than vinyl - it resists expanding and contracting in any climate. More strength means less material, giving you more of your beautiful views for the value. So you get a tight, snug fit that will last.


Bigger View with Fiberglass Windows


Specifically designed to resist warping and weathering in any conditions for long-lasting durability. Because of Ultrex’s incredible strength, frames can be built more narrow — so you get more incredible views for your money.

Fade-Resistant Finishes


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 - meaning your bronze windows will stay bronze for years to come.
