When the moisture suspended in warm air comes in contact with a cold surface, the water vapor condenses back into its liquid state. This is why a cold glass of water left under the sun appears to “sweat”. Condensation happens whenever there’s a difference in temperature between two objects. With windows, this is a completely normal occurrence, although it’s understandable how it might cause some alarm.
Condensation in windows means that your weatherproofing seals are working as they should. However, if you want to minimize its effects, there are a few steps you can take.Reducing Humidity
Some daily activities can increase the relative humidities inside your home. Cooking, taking a shower and even washing your hands can all contribute to the amount of moisture indoors. This could lead to increased amounts of condensation on your windows. There’s no way to avoid doing certain activities, but there are ways to reduce the amount of water vapor they release in the air. Dryers and washers can be vented so that the extra moisture is directed outdoors. Similarly, consider proper ventilation in your attic and crawlspace to further lower your indoor humidity.Vapor Barriers
Maintaining your home’s thermal envelope includes protecting it against the increased levels of moisture retained in your crawlspace. Vapor barriers help reduce the vapor pressure that can force water molecules through your home’s walls, whether it’s made of wood, vinyl or concrete. Vapor pressure is one of the biggest sources of condensation in any home.
