WHAT MAKES A WINDOW ENERGY-EFFICIENT? – PART 1: ENERGY-EFFICIENT WINDOW MATERIALS

The increasing interest in achieving energy efficiency is mainly fueled by two things: a better awareness of the environmental impact of energy use and the need to save on costs as electric bills rise. A number of factors determine how energy-efficient a home can be, but faulty windows have been shown to decrease energy efficiency by facilitating heat transfer and air leakage. Improving energy efficiency then can be partly achieved by ensuring windows are in great shape. In addition to having windows in good working condition, having windows made of the right material may have a bigger effect on your efforts to achieve energy efficiency.

Here’s a quick overview of different window materials and how they can contribute to your home’s energy efficiency.

  • Metal. Metal-framed windows are usually made of aluminum or steel alloy. Metal is a poor insulator, but metal frames with an insulated thermal break can slow the transfer of heat.
  • Wood. Wood frames, on the other h and, are an excellent insulator, making them ideal for use in areas with cold climates. By offering reliable insulation, wood eases strain on HVAC systems by helping to maintain indoor temperature.
  • Vinyl. One of the things that makes vinyl a favorite among homeowners is that it is very easy to maintain. A vinyl window also offers great thermal insulation, helping prevent outdoor heat from getting in and indoor heat from getting out.
  • Composite. Windows with composite frames combine the best that wood and vinyl has to offer, resulting in maintenance ease and superb insulation that blocks thermal transfer hundreds of times better than metal .

Aside from materials, what else can make a window energy-efficient? In Part 2, we’ll be discussing how window styles can also have a h and in improving energy efficiency in your home.

"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!!"
