Ultrex® Fiberglass: The Finest Window Material of All

Superb Window Material 

Ultrex fiberglass is eight times stronger than vinyl, the standard material for windows today. Just one square inch of this state-of-the-art material can support around 34,000 lbs – which is heavier than two giant monster trucks!

It also has extremely high tensile strength. Vinyl only has a tensile strength of 7.0. Ultrex fiberglass, on the other hand, has a tensile strength of 40.14, which means it can handle elements that would destroy a regular window. Its strength alone is the reason we always use this material for window replacement. Window and siding companies understand the importance of high tensile strength.

Energy Efficiency

Ultrex fiberglass isn’t just strong; it’s energy-efficient, too. These windows boast dual-pane windows with Low-E coating, which lowers energy costs in your home. It can cut heat loss by up to 34% when the weather gets colder, and cooling costs by up to 38% when the weather gets hot. Their high ENERGY STAR® ratings are a testament to how beneficial these windows are for your home.

Superior Paint Finishes

When you have us install your new Ultrex® fiberglass windows, we’ll also provide you with the industry’s finest fiberglass finish. This material has an innate acrylic finish, and this helps with color retention. Your new windows won’t just last a long time; they’ll also retain their beautiful finishes. Unlike vinyl, Ultrex® fiberglass windows can come in darker finishes without increasing heat absorption and UV degradation.

We were so happy with the roofing, siding and pertego job PJ Sullivan did for us. We couldn’t have asked for a better company to do this for us. Pete was very attentive and visited our home at least 3 times a week and that was important for us.
