What Causes Window Condensation?
Windows often get fogged up. They collect moisture easily. It’s a common problem that tends to be very annoying for homeowners. What’s more, it causes unnecessary and unhealthy amounts of moisture inside the home.
Most people think that there is no solution for window condensation. However, in reality, you only need to understand why it happens, and then you’ll know how to deal with it. Let’s take a look at why window condensation occurs and then offer some solutions:
What Causes Condensation on Windows?
First things first – windows do not cause condensation. Moisture collects on windows for the same reasons it collects on bathroom mirrors and all other glass surfaces – it’s a cool surface that makes condensation more visible.
The main reason why condensation occurs is when humid air gets in contact with a cold surface. That’s also why condensation is most common during winter. However, it’s not all about the surface. The warmer and more humid the air is, the more chances there are for moisture to collect on colder surfaces like window glass – which tend to be the coldest in any home.
So, in essence, the most common reason why you get condensation on your windows is that the air in your home is very humid. Now, it’s humid mostly because of everyday living. Showers, baths, cooking, cleaning, doing laundry, and many other common, daily chores steadily increase the amount of moisture in the air. That moisture then sticks to windows as there’s nowhere else for it to go.
What’s more, the better insulated your home is, the more warm and humid air gets trapped inside, especially in the winter. In turn, you get more condensation on your windows.
If condensation forms on the outside of the windows, you’ll have to let it subside on its own. It’s a normal atmospheric phenomenon that tends to happen during the summer when cold nights end and warmer days start.
So, how do you deal with condensation? How do you reduce it?
Ways to Deal with Window Condensation
- Open the windows for a few minutes to let the humidity escape. However, remember that this is only a temporary solution, and the things that are causing humidity will continue to cause it, regardless.
- If you have a humidifier, set it to the recommended level in the winter.
- Buy a humidistat to monitor the amount of humidity in the house.
- Buy a dehumidifier and place it near the windows with the most condensation.
- Ventilate things like gas burners and clothes dryers to the outside.
- Install exhaust fans in the kitchen and the bathroom.
- Keep your attic vents clear and open.
- If you have plants, make sure they are grouped in a sunny room and don’t overwater them in the winter.
- Weather-strip your windows. It will prevent condensation and lower your energy bills.
- Use storm windows on older windows, as that helps reduce condensation by keeping the inside part of the window a bit warmer.
