What Makes Replacement Windows ENERGY STAR® Qualified?

You know you’re purchasing energy-efficient windows if they are ENERGY STAR® qualified. These windows add more protection to your home and help you save on energy costs.

What Makes Replacement Windows Energy Star Qualified

In this post, your trusted local windows contractor, Renewal By Andersen® of St. Louis, discusses what makes windows ENERGY STAR qualified.

Characteristics of an Energy-Efficient Window

Energy-efficient windows have multiple panes with an air- or gas-filled space in the middle. Odorless, colorless and non-toxic gasses like argon and krypton work better than just air in preventing the transfer of energy.

The more panes the windows have, the more energy-efficient and impact resistant they can be if they’re well-made. Spacers keep the glass panes at a safe distance from each other. Non-metallic and metal spacers insulate pane edges, helping reduce heat transfer.

Low-e glass has a special coating that reflects infrared light, retains indoor heat in the winter and keeps hot air outside in the summer. This glass also protects you from harmful ultraviolet (UV) light and helps prevent furniture from fading.

Renewal by Andersen of St. Louis offers ENERGY STAR-rated windows to help reduce your energy costs and improve your home’s appeal. We offer energy-efficient and beautiful bow, picture, double-hung and casement windows.

ENERGY STAR® Framing Materials 

An energy-efficient window has top-quality frame material. Such materials should be low-maintenance and highly insulating.

Fiberglass is a durable and low-maintenance material. Fiberglass frames can be hollow or filled with foam insulation. Vinyl frames excel in thermal insulation, and they may also be hollow or filled with foam insulation.

Aluminum frames are a eco-friendlier option as they are recyclable and usually made of up to 15% recycled materials. Wood frames should be clad with aluminum or vinyl to reduce maintenance. Meanwhile, composite frames are created from different materials mixed together to make low-maintenance and durable windows. Probably the best type is Fibrex®, our proprietary framing material developed by our parent company, Andersen®.

"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!!"
