Window Energy Efficiency

What You Need To Know To Make The Best Buying Decision.

If you’re shopping for replacement windows in Lombard, Elmhurst, and the surrounding Western Suburbs, energy efficiency is hands-down one of the most important things you should consider. Energy efficient windows will not only make your home more comfortable during the frigid Illinois winter, but can also considerably cut your energy costs.

So just what, exactly, makes a window energy efficient? It’s not one thing in particular, but a combination of features working together—a well-insulated frame, quality glass, good weather stripping, and more.

Honestly, describing the components of an efficient window in detail is pretty complicated, so here’s all you need to know: If you want to see how efficient a window is, just look at the NFRC label on its glass pane.

The picture below explains the NFRC label ratings, along with how windows with good NFRC scores benefit your home. For reference, as of 2016, Energy Star has determined that windows with a U-factor of 0.27 and air leakage rating of 0.30 or less are considered optimal for Illinois weather.

“We are 100% pleased with the door we ordered through David at The Door Store. They custom stained it and it looks perfect. The installer was very friendly and skilled and took his time to do it right. Nothing on our 60's home is perfect or square, so it probably wasn't the easiest install. I would highly recommend them!”

“Recently our home in Berkeley received vinyl replacement windows, a bow window and steel doors. I wish to write a big thank you to the gentlemen who installed the above improvements. The windows and doors look beautiful. The men were enjoyable to have around. They tolerated our questions and our neighbor's questions with genuine concern and patience. Paul and I appreciate their high quality of workmanship. Thank you for a job well done.”
