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.

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®.

Reviews

"Love the windows and patio door. We want to finish the whole house when we can financially. We give Anderson and employees, especially the sales rep Mike that came to our house, the highest rating. Mike was knowledgeable and courteous. Also not high pressure."

"Our installation team was top notch. While they said they were sending a "team"to install 21 windows it was only two people. But I see why, the process was seamless and everything was done correctly and consistently with the leadership of Clayton. We had a tiny problem with one window within a week of installation and their response time was prompt to remedy the situation. Our windows are beautiful. Our home is warm and cozy."
