What Makes Replacement Windows ENERGY STAR® Qualified?

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®.

"Everyone I worked with from setting up the initial appointment to the salesman to the installers to everyone who checked on us and kept us updated on the progress of the windows was courteous, professional, and responsive. There’s always someone who is willing to answer your question without jumping through hoops which is rare these days! The installers were on time, did a beautiful job, cleaned up the space better than I expected, and even helped me with some blinds I couldn’t remove and fixed my squeaky front door! I’ve already recommended Renewal by Anderson to friends!"
