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.

"This was one of the best experiences I've ever had with a company. I ordered the windows in November and was told they wouldn't be here until July. That kind of delay the new norm so I wasn't a bit upset with the timeline. I was given an early present when they called to say the windows would be in at the beginning of May. We agreed on the week of May 16th to do the installation, there were 30 windows and a sliding door to install. They arrived promptly on their scheduled install date, and got straight to work. By the end of day one, they had all the upstairs windows complete and their work was incredible. Day two came with more of the same, the crew showed up promptly, got straight to work, and when they left they had every window downstairs installed. The third day they again arrived on-time, and got to work installing the door. The door and windows are perfectly installed. The two lads that did the installation did a phenomenal job, and were friendly to boot. I would give them more business if I had any :) The service I received from the company was great. They kept me abreast of anything that was going on with my order. I appreciate my concierge, Christina, she was good at communicating timelines and getting everything scheduled."

"The two installers were great! They were polite and hard working and they cleaned up all the outside and inside. It was like they were never here. As for the windows, I love them, not only looks great, they are efficient. Now every window in my home has Renewal by Anderson."

"We had the pleasure recently of having Andersen replace all of our windows. From the very first interaction with the office personnel through the completion of the project, they have been nothing but professional. From Brian our sales rep to Christina the appointment scheduler, they were a pleasure to interact with. Installers Keith, John, and Evan were fantastic to work with. They went above and beyond to repair an area which was slightly damaged during the removal of a window...caulked and painted it. They took extra precaution to ensure the floors were covered while working inside and cleaned up each day inside and out. We love the look of our new windows and can't wait to enjoy the savings in utilities they'll provide. Thanks so much Renewal by Andersen!!"
