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. Not all fiberglass materials are the same — and finishes can vary across manufacturers.


While vinyl is frequently the cheapest option, vinyl windows and doors can warp, shift and crack under everyday conditions.


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.
