A Quick Guide on Energy-Efficient Windows

High-performance, energy-efficient windows are an integral part of any modern structure. While most homeowners have a pretty good idea of what window style they want, when it comes to technical specifications, they are a little less sure. To remedy that, here is a basic guide to help you get started.

 Energy-Efficient Windows

Insulated Glass

Insulated glass or glazing consists of two or more glass panes that are separated by a vacuum or gas-filled space to minimize heat transfer. A window with insulated glass is commonly known as a double-, triple- or quadruple-paned window depending on how many panes of glass are used.

Low-E Glass

Low-emissivity (Low-E) glass minimizes the amount of infrared and ultraviolet (UV) light that comes through the glass without minimizing the amount of light that comes through your replacement windows. Low-E glass has a transparent, microscopic coating that is directly applied to the surface to help reflect heat and keep the temperature in your home at an ideal level.

U-value and R-value

U-values measure how effective your windows are as an insulator. Simply put, the lower the U-value is, the less heat is lost, and the more insulation it provides. R-values, on the other hand, are usually cited when discussing walls and ceilings. It is important to note that R- and U-values relate to each other inversely. The higher the R-value is, the better insulated your walls and ceilings are.

"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!!"
