ENERGY STAR Window Requirements for Baltimore MD Homeowners

Which Window Specs Actually Matter In Baltimore

Most homeowners do not need to memorize every rating, but a few numbers do deserve attention: U-factor, solar heat gain coefficient, and air leakage.

SHGC is about how much solar heat passes through the glass. In Baltimore, that can make a noticeable difference on sun-exposed windows, especially in the late afternoon.

Air leakage is the detail that gets missed most often. A window may have good lab ratings and still feel drafty if the frame or installation is off.

For older Baltimore homes, especially brick rowhomes, frame material and installation often matter nearly as much as the glass. If the opening is out of square or the old frame is failing, even a strong rating will not save the job.

How Local Homes Change The Best Choice
