Benefits of Renewal by Andersen® Exclusive Products

Replacement window company, Renewal by Andersen® is known for its high-quality and energy-efficient products. Our windows are made from Fibrex® material, which is an Andersen-exclusive composite that features the strength and stability of wood and vinyl’s ease of maintenance.

Discover what it means to have Renewal by Andersen exclusive products in this post.

Energy Efficiency

Fibrex material has superior thermal insulating properties that help keep your home warmer in the winter and cooler in the summer. Because your heating and cooling system doesn’t have to work as hard, you can enjoy significant savings on energy costs. Further, our glass options provide unique benefits for heating, cooling, visible light transfer and ultraviolet radiation reduction. With our expert installation, you’ll have windows that will help you save money and increase your home’s curb appeal.

Strength and Durability

Fibrex is twice as strong as vinyl, meaning its weathertight seals stay intact. It’s designed to withstand extreme temperature and weather changes, meaning it’s ideal for all climates.


Whether you need new double-hung, casement or custom windows, you can count on us. The strength of Fibrex material allows us to create narrower frames. With narrower frames, you’ll have more glass area and view. Also, the extrusion process lets us create your windows into any shape or style. No matter what architectural style you have, we have windows that are perfect for your home.


Renewal by Andersen windows are warranted not to flake, peel, blister, rust, pit or corrode. Our windows are also made to last. They remain easy to operate as the day they were installed even after two decades.

"I highly recommend Renewal by Andersen. We were treated well and everything went smoothly from start to finish. The company kept in contact with me before, during, and after the installation and let me know what to expect. I'm in love with my new windows! I will be using this company again when we refinish our basement. "
