A New, Efficient Entry Door Can Cut Your
Energy Costs Substantially.

Here’s What You Need To Know About Exterior Door Efficiency To Keep Energy Bills Low & Your Home Comfortable.

If your entry door is 10 years old or more, it is most likely increasing your energy bills. Older entry doors are often poorly insulated and have lost that tight fit that prevents drafts. That’s why it’s so important to consider energy efficiency when shopping for entry door replacement in Glen Ellyn, Naperville, Wheaton, and the surrounding Western Suburbs.

By choosing an energy-efficient entry door, you ensure yourself lower energy bills and a more comfortable home. To help you make the right buying decision, here are 3 important energy factors to consider when shopping for a new door.

Air Leakage

Air Leakage measures the rate of air movement around a door in the presence of a specific pressure difference across it. Weatherstripping (door sweeps, tension seals, magnets, etc.) is the ideal way to reduce air leakage. The lower the air-leakage rating, the tighter and more efficient the door.


U-Factor is important to consider if you want glass in your entry door. This is the rate at which the glass window in your door conducts non-solar heat flow, which is expressed as a number between 0 and 1. The lower the U-Factor, the more efficient the product. For reference, Efficient Windows Collaborative recommends windows with a U-Factor of 0.32 or lower for our area.

Solar Heat Gain Coefficient (SHGC)

This is the measurement of solar radiation admitted through a window or door conveyed as a number between 0 and 1. The lower the SHGC, the less solar heat the door transmits. SHGC is more important in hot states like Arizona, but it’s still an important rating to consider if you want to reduce the amount of heat your exterior door lets in during the summer.

“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.”
