Andersen Corporation continues to change the window replacement industry one innovation at a time. One of their greatest inventions is Fibrex®, a leading-edge composite material. For 30 years, Andersen researched and developed Fibrex to incorporate the best features of various materials.


At Renewal by Andersen® of San Antonio, Fibrex makes our window and door installation in San Antonio easy and high quality.

The Unique Features and Benefits of Fibrex Material

Because of Fibrex, the products we install offer the beauty and strength of wood without the upkeep hassle. In fact, Fibrex has the maintenance ease of vinyl. Another great benefit of Fibrex is durability. Some windows tend to expand and contract over time. Our replacement windows are two times stronger compared to other materials. You can enjoy windows that look as good as new for a long period.

Fibrex also has superior thermal insulating properties that helps improve your home’s energy efficiency. If you want to save on energy costs this season, consider our replacement windows. Did you know that 40% of the raw material in our Fibrex frames is made from clean reclaimed wood fiber? Our products have met Green Seal’s science-based environmental standards. This means our windows and doors are highly sustainable options that are perfect for your home.

Renewal by Andersen’s Quality Services

If you want to change the overall appearance of your home, our replacement windows are your best bet. We have worked with plenty of homes, providing window solutions that give major impact. For instance, in place of three mini windows, we can install one huge picture window. If you have two windows, we can replace them with a box bay type, which can improve your home’s curb appeal. We can also upgrade former window areas into entryways and install patio doors. These upgrades will completely transform the appearance and functionality of your home.

Some window companies use an intermediary to handle business. However, with us, there is no middleman. If you encounter any problems regarding our products, you can go to us directly. We are both the manufacturer and installer of our products. Our teams are licensed, insured, and skilled to do all kinds of installations. Because of this, many of our installations can be done in one day. How convenient is that!

"If I could heap more praise on Renewal by Andersen, I would have to buy a dump truck. They recently replaced 13 doors in my home in an exemplary fashion. Very professional, efficient and, in my estimation, worth every penny."
