Materials Matter
Evaluating window material options
The best products are made from the best materials. Let’s take a look at common materials for replacement windows and doors.
Infinity's Ultrex® fiberglass
Our Ultrex fiberglass is an innovative material pioneered over 20 years ago, making it one of the first premium composites on the market. Ultrex fiberglass replacement windows and doors continue to deliver strength, stability, and durability. Our proprietary acrylic finish is three times thicker than the competition.
Other fiberglass
The strength and durability of fiberglass make it a good option for replacement windows and doors. However, not all fiberglass materials are the same and finishes can vary across manufacturers.
Vinyl
While vinyl is often the cheapest option, vinyl windows and doors can warp, shift, and crack under everyday conditions.
Wood
Wood windows offer more strength, stability, and beauty than vinyl, but they tend to require more maintenance than other window materials.
Vinyl/wood composites
Vinyl/wood composites like Fibrex® are made from vinyl infused with wood fibers (sawdust). Fibrex isn’t fiberglass.
Fibrex is a registered trademark of Andersen Corporation.
