Condensation occurs when warm and cool air meet. You may assume that there’s a problem with your new windows if they’re covered in condensation. However, this is simply notifying you that there’s excess humidity in your home. For example, if you step out of a hot, steamy shower, you’ll notice that the toilet tank is covered in small droplets of water. The bathroom mirror will also be clouded over. The same process occurs when mist appears on the glass in your new windows.
There are a number of ways to stop condensation forming on your windows.
If you’re using a humidifier, turn it down or even turn it off altogether, if you feel comfortable doing that. Bear in mind that if your humidifier is set at 30%, you need to consider all the factors that may be contributing to your home’s humidity level, which may actually be closer to 70%.
If your windows have blinds, raise them slightly above the ledge at night. While we understand that the blinds are a privacy feature, raising the blinds just one or two inches from the ledge allows air to circulate onto the glass, when the temperature falls later in the day.
Screens can restrict airflow to the glass, so these should be removed from venting windows.
If particular rooms have a more pronounced problem with condensation, make sure that the heat registers are open in those rooms.
Leave bedroom doors open at night if possible, to improve the air circulation in your home.
A Breath of Fresh Air
Even if you follow these steps, it may still take a while for condensation to decrease. You may not notice a change right away. A range of daily activities, including showering, cooking, washing dishes, or doing laundry, causes humidity in your home. Indoor plants contribute to the humidity level too. Human breathing is also a factor and this is hardly something that you can eliminate from your daily routine.
