Are double-pane or triple-pane windows better for Chicagoland?

Jul 05, 2026

Double-pane with Low-E glass and argon is the standard, and it performs well for most Chicagoland homes. Triple-pane adds a third layer of glass for even better insulation and noise reduction, which can be worth it on exposed lots, lakefront homes, or the coldest side of the house. We help you decide where the upgrade pays off and where double-pane is plenty.

 I am very happy with the new windows McCann installed for us. They were able to install them quickly and did a very thorough job. Mark and Angel did a great job! I would highly recommend McCann to anyone looking to replace their windows. Thank you McCann!

 I can only say good things about the people I dealt with with McCann, from Kevin, and Jim, and all the installers. They did a great job, their customer service was excellent, they were very clean, and I am as happy as can be. They were professional, and a pleasure to do business with.

 Just nice people all around. They know their stuff, have several quality options to choose from (less to more expensive), & didn’t pressure sell. Easy install, quality workmanship. Super satisfied with our experience.
