Energy Efficiency

The superior thermal insulating properties of Fibrex® material help your home stay warmer in winter and cooler in summer—and help you save money on your energy bills.

Our different glass options offer unique benefits for heating, cooling, visible light transfer, and UV reduction.

When you combine that with our expert installation, you’ll end up with a replacement window that will help save you money and look beautiful, regardless of the climate.

Strength and Durability

Twice as strong as vinyl, Fibrex® material means weathertight seals stay weathertight. Its durable nature means that it can stand up to even the most extreme temperature swings, maintaining its stability and rigidity in all climates.

Beauty

The strength of Fibrex® material means narrower frames; narrower frames mean more glass—and more view. Plus, the extrusion process allows us to craft your windows to any shape—meaning you can match the architectural style of your home…or define a new look.

The process also fuses the color into the material, offering you a wide palette of long-lasting colors to choose from—including dark exterior colors not found with most other replacement windows.

Maintenance

Your Renewal by Andersen® windows are warranted not to flake, rust, blister, peel, crack, pit or corrode. Plus, our windows stand the test of time and are as easy to operate after 20 years as the day they were installed.*

Take a look and we think you’ll agree—replacement windows made of Fibrex® material are the right choice for your home. When you’re ready to learn more, schedule a free consultation with us today.
