If you’re a homeowner who’s considering replacement windows, you’ve probably been thinking about energy efficiency. One of the biggest potential benefits of new windows is improved energy efficiency for your entire home, which can lead to energy savings and comfortable interior temperatures—but which option is best? Read on to discover which replacement windows offer the most energy-efficient design.

What Makes Windows Energy-Efficient?

Determining which windows are most energy-efficient starts with understanding what components improve thermal performance. There are a few key features that almost all energy-efficient windows possess, including:

High-Quality Frames

Robust frames ensure that windows retain their shape, which is key in stopping future drafts and leaks. Additionally, well-made frames are less likely to transfer heat and energy into and out of your home.

Multi-Pane Glass With Low-E Treatments

One of the most-effective methods for improving window efficiency is by utilizing multiple glass panes, which help insulate the windows and improve thermal performance. Low-E treatments are also essential and help glass deflect UV radiation.

Gas Fills and Frame Insulation

Insulation is important for energy-efficient windows, including in the panes themselves. Gas fills provide impressive thermal improvements for multi-pane windows, and frame insulation can help any window perform better.

Make Your Replacement Windows More Energy-Efficient

While there are many factors to consider when it comes to replacement windows’ energy efficiency, the good news for homeowners is that practically any window can be made more efficient with help from a window contractor. For example, at Hegg Windows & Doors, our replacement windows are fully customizable and can be upgraded with premium enhancements to improve their thermal performance, all without sacrificing their attractive appearance and curb appeal.

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!
