What Makes a Window Energy Efficient?

One of the benefits of replacement windows that is most often touted is their energy efficiency. And, considering how many homeowners wish to improve their homes thermal performance with new windows, it makes sense that it’s a topic on everyone’s mind. But if you’re not exactly a window expert, you might be confused as to what actually makes a window energy efficient. The good news is that the answer is likely less complicated than you imagined.

Insulation Is Important

When it comes to determining your window’s energy efficiency, insulation in one form or another is the most important aspect. The two areas of a replacement window that benefit the most from insulation are:

The Frame

Modern, energy-efficient window frames have gaps and pockets that are a great place for insulation. Some frames have optional hard insulation and others will simply have air pockets, but the end result is frames that slow temperature exchange.

The Panes

Modern multipaned glass windows have gaps between each pane of glass that improve insulation naturally, which is part of the reason that double-paned windows are so much more energy efficient than their single-paned brethren. Premium windows will include inert gasses in between frames to provide additional insulation.

Glass Treatments Are Crucial

The last piece of the puzzle when it comes to window’s energy efficiency is glass coatings. Popular options, like Low-E coatings, help reflect heat and light without disturbing visibility, and have a big impact on overall efficiency.

I'm a big fan of HEGG Windows because of their customer service, attention to detail, and amazing communication. I had got several quotes before deciding on HEGG and what helped with my decision was that they are a local company, sales was not pushy, professional, price was reasonable, and communication/follow-ups were so nice. The installers were great and the quality inspection afterwards was helpful - they already found something to fix (hardware replacement) and are on it! I feel really taken care of. Thank you HEGG! Will definitely look for you for more windows in the future.

Probably the best company I’ve ever dealt with for home improvement. We just had a small, one door project and I felt like they treated us like we had a huge whole house window install. Communication was excellent from the company at every step. Final product was high quality, and they even did a follow up inspection to make sure we were satisfied. I will definitely use this company again when the need arises.

Highly recommend Hegg Windows and Doors! Knowledgeable, professional, communicative, great selection, and low pressure sales approach! Recently had sliding doors, 3 season room windows, entry doors replaced. Very happy with end result. The walk-through after installation addressed any questions or adjustments needed. They even caulked and touched up paint inside and out! A rare company built on customer satisfaction.

The whole team was great to work with. They are skilled in what they do and very professional. We had a small job of replacing just two windows and they did an excellent job. We appreciated the follow up inspection and lessons on how to care for our new windows. Kudos to Josh, Virginia, and the whole team.

Excellent communication from the beginning of the process to the final QA walkthrough after the installation. This is the type of company you WANT to do business with rather than a company you have to work with. Excellent organization!
