Low-E Glass Benefits for South Facing Baltimore Homes

Why South Facing Windows Feel Different In Baltimore

South facing windows take the hardest hit from the sun for most of the day, and in Baltimore that means more heat gain in summer, more glare at certain hours, and more wear on interior finishes over time.
