The Benefits of Renewal by Andersen® Exclusive Products

The leading windows installation and replacement company, Renewal by Andersen®, has built a track record of creating high-quality and energy-efficient products. Our windows are made of Fibrex®, which is proprietary to Renewal by Andersen products. Fibrex is known for its strength, durability and ease of maintenance.

The Benefits Of Renewal By Andersen Exclusive Products

Strength and Durability

Fibrex is twice as strong as vinyl material. This means that weathertight seals maintain their form. Its durability is displayed when faced with nature’s harsh elements. It maintains its form and rigidity in all climates

Energy Efficiency

Fibrex has superior thermal insulating properties that help keep your home warmer in the winter and cooler during the summer. Since your heating and cooling system doesn’t have to run all the time, you can save a lot on energy costs. Furthermore, our energy-efficient windows offer unique benefits that aid with cooling, heating, visible light transfer and ultraviolet (UV) ray reduction.

Beauty

Our windows come with narrower frames, which results in having more glass area and a wider view. Additionally, our extrusion process allows us to create windows in any shape and size, meaning that we can create a window that complements your home’s architectural style. We also have a wide range of colors and finishes to choose from which gives you a lot of combinations to amplify your home’s beauty.

Maintenance

Renewal by Andersen windows are known to stand the test of time. Our manufacturing processes ensure that our windows do not flake, peel, blister, rust or corrode. They remain easy to maintain as the day they were installed even after 20 years.

Reviews

"Renewal was fantastic! They kept you in the loop from ordering to installation. They informed you at every step of the process of what was happening. The installers were kind, courteous, and professional. Everything was cleaned up after the installation. It was as if they hadn't been there except to see your beautiful new windows. I highly recommend them."

"3rd time using RBA for window replacement. Again, a very positive experience, the windows are great, the installation was done right, the professionalism was apparent from start to finish. Still have existing windows to be replaced and will definitely use RBA again to do it in the future."

"Renewal by Andersen was a good experience for us in replacement of our windows. From the initial meeting with the sales representative, Leslie, through the waiting period for manufacturing, and then to the installment process, our experience was excellent! Communication is key for me and we were kept informed and updated as our windows were being ordered and manufactured. Calls to update us on the installation process were welcomed and appreciated. They know how much is too much so they don't pester you with unnecessary contact. We love our new windows!!! Did I say that already??😂 We can tell a major difference in reduced Street noise and also the temperature at our windows. Excellent company, highly recommend!!"
