Window U-Factor Recommendations for Maryland Homes

Why U-Factor Matters When Replacing Windows In Maryland

U-factor deserves attention because it measures how much heat escapes through the window assembly, and that matters more than a lot of sales language does.

In practical terms, a window with a lower U-factor helps keep heated air in during cold weather and keeps conditioned air from leaking out when the house is under summer load.
