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 service provided by Renewal by Anderson is great, both on the sales and the installation side. Our sales representative was very accommodating and helpful. The installation crew was efficient and they all were professional. These are really nice windows and a great upgrade especially from builder-grade windows."

"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!"
