We know our customers are just as interested in energy efficiency as they are the appearance of their windows. But when the jargon comes out – R-values, UV ratings, thermal efficiency – it’s easy to get lost in the numbers. What sets Renewal by Andersen apart is our focus on the whole window performance for improved comfort of your home. Where competitors concentrate solely on glass, we understand that energy efficiency relies on the right combination of glass, frame, and installation.

Our windows are made from Andersen's exclusive composite Fibrex® material that lasts longer, performs better, is twice as strong as vinyl and unlike wood, requires virtually no maintenance.**

Each Renewal by Andersen glass option offers four unique benefits for heating, cooling, visible light transfer and ultra violet (UV) protection. The glass solution for you depends on the climate you live in, the architectural design of your home, and the orientation of your windows to the sun. Click here to learn more about our glass options.
