Window U-Factor Recommendations for Maryland Homes

Why U-Factor Matters In Maryland's Climate

U-factor measures heat flow through a window assembly, so the lower the rating, the better the window resists heat loss.

Maryland homes see enough seasonal change that a window with the wrong thermal performance can feel drafty in winter and overly warm in summer.
