WHAT MAKES A WINDOW ENERGY-EFFICIENT? – PART 2: WINDOW STYLES & ENERGY EFFICIENCY

It’s not just the materials that make a window provide better energy efficiency, what with different styles offering their own way of keeping a home ventilated, insulated and illuminated. Knowing what each style has to offer can help you decide which one to get to achieve your energy-efficiency goals.

Double-Hung Windows

Double-hung windows provide great ventilation control as both sashes are operable, allowing homeowners to use just one or both depending on their needs. They also let in moderate amounts of natural light, contributing to daylighting needs.

Casement Windows

Because casement windows can be opened all the way, they create the best opportunities for ventilation. Their large openings let a lot of air in and out and the sash can be angled in such a way that it captures breezes effectively.

Sliding Windows

Sliding windows can only open as wide as one sash. However, sliding window sashes are generally bigger than the ones double-hung windows use so the former is able to offer better ventilation. Glass areas are also usually unobstructed by muntins, letting in a lot of light into a room to aid in illumination during the day.

Bow & Bay Windows

Bow and bay windows are both made up of a series of smaller windows configured together, creating large areas of glass that let homeowners take advantage of natural light. All those windows also mean more openings, allowing bow and bay windows to provide excellent ventilation and expansive views.

Picture Windows

Picture windows are also known as fixed windows because they can’t be opened. This means they can’t offer ventilation because they are sealed, but picture windows are the best option for optimal insulation. Picture windows also have some of the largest glass areas around, making them great daylighting tools.

We’ll be wrapping up this three-part blog series by talking about how window features contribute to achieving energy efficiency in a home, complementing style and material options.

"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!!"
