As a homeowner, it’s likely you’ve noticed times where your windows are “sweating”, especially during the winter. While this might alarm you, it’s usually not something you need to worry about, as condensation can form on even the best windows. In fact, it’s an indicator that your window is performing well and is very energy efficient. While this condensation is most common during the winter, it’s also possible for it to happen in the summer too.
In this post, Comfort King Windows and Doors discusses why your windows sweat during the summer.
High Outdoor Temperatures vs. Low Indoor Temperatures
Just because your window has condensation doesn’t mean you have to get new windows. Condensation occurs when warm, moist air comes into contact with a cold object. Since your window will likely be cold due to your home’s air conditioning, the water vapor from the warm summer air can come in contact with the cold window and cause it to sweat. Your window’s Low-E coating also plays a part in this as it helps keep the heat outside. When the summer nights are cool, your Low-E coated windows can develop condensation on the outside.
Another possible cause of summer condensation is indoor moisture, which in turn can be caused by any everyday activity that uses water. For instance, summer is a hot and uncomfortable season for many people, which often compels household members to shower more frequently than usual. Every shower you take releases an additional half pint of moisture into the air, which can cause window condensation. Cooking can also add to indoor moisture.
