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.

"The salesman had previously sold us new windows and was very informative and not a bit pushy. The installation was excellent and as advertised absolutely nothing was left for me to clean up. Highly recommend Renewal by Andersen of St. Louis👍"
