There is always the why question when it comes to your windows sweating. Everyday daily activities such as showering, cooking and believe it or not even breathing all add moisture to the air. When air warms it expands allowing it to hold more moisture. It then contracts as it cools reaching its saturation point then releases its excess water in the form of condensation. The warm humid air then comes in contact with cold window glass it cools and condenses. So to help out with this problem (that most of us have) here are just a few suggestions that could help.
-Lower your thermostat to 66°-68° F
-Vent gas fireplaces, or limit their use, and don’t use older unvented gas space heaters
-Be sure to seal up any cracked windows
-Make sure that your clothes dryer is vented properly to the outside
-If the problem is really bad you should consider installing a dehumidifier
I hope these simple steps can reduce the window sweat in your home, it’s never fun or visually attractive to look out a window and see nothing but water drops and condensation so I hope this can help fix that problem for you! Especially if you have a really nice view!
