As your local window contractor, Renewal by Andersen® of Knoxville is helping homeowners make their homes more energy-efficient through the windows we install. While our use of fibrex® makes our window frames durable and ensures energy efficiency, it’s the glazing we use that make it as energy-efficient as possible.

Part of the reasons why window replacement matters is that doing so helps enhance your  Knoxville home’s overall value and curb appeal. However, there are ways to make your new windows even better. One way is to add window boxes.

At Renewal by Andersen®, we value energy efficiency and your protection against any kind of weather. That’s why we recommend our High-Performance™ Low-E4® glass for any window replacement project. We push the limits of glass technology by providing an amazing experience for your family while maximizing energy performance.

If your home is based on traditional architecture, you should consider choosing double-hung windows for your next window replacement project. It is the window style that strikes the perfect balance between familiar features and modern flair. 

For over 100 years, the name Andersen® has become synonymous with quality replacement windows and patio doors. Renewal by Andersen is more than just a replacement window contractor, though. We are the Andersen Corporation’s full-service replacement window division, and we carry this tradition through the Renewal by Andersen Signature Service.
