WHAT MAKES A WINDOW ENERGY-EFFICIENT? – PART 3: ENERGY-EFFICIENT FEATURES IN WINDOWS

Choosing a window made from the right material and in a particular style can greatly improve your home’s energy efficiency. However, certain features also contribute, ensuring the best application of ventilation, insulation and illumination for your property. The following is a rundown of some of the most energy-saving window features.

  1. Weatherstripping

Weatherstripping refers to the strips of rubber or vinyl found on the edges of the window frame. When the window is fully closed, the weatherstripping acts as an insulator, sealing off gaps between the sash and the frame to prevent moisture, wind and dirt from getting inside. Having good quality weatherstripping helps prevent unregulated outdoor air from getting inside and affecting the stability of indoor temperatures.

  1. Low-E and Reflective Coating

Low-emissivity and reflective coating enables a window to block heat from the sun and reflect heat back inside your home. They differ, however, in that low-E coating does not impede the level of natural light a window lets in.

  1. Multi-Pane Glazing & Gas Fills

Multi-pane glazing means more than one layer of glass is used in a window. Using several glass layers improves insulation because less heat is transferred. This function is further complemented by heavy gas (usually argon or krypton) that fills the space between the layers of glass and slows heat transfer.

  1. Window Treatments

Though not exactly a window feature, the use of window treatments improves energy efficiency by further preventing heat inside from getting out and heat outside from getting in. With air leakage further kept to a minimum, indoor temperature remains stable.

Windows look great but they can be greatly functional as well. Making the effort to choose energy-efficient windows when you’re looking for a replacement will help you address more than one need, ensuring you make the most out of your investment.

"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!!"
