Does closing blinds help with condensation?
Any blind that is fully open will avoid trapping condensation; but few of us buy blinds just to never use them, and so the blinds that will help you to reduce condensation build-up are those that you can close or partially close while still maintaining some airflow to the window behind them.
It's important to note that windows covered by blinds and curtains are more likely to experience condensation. This is because there is reduced airflow getting to the surface of your window, trapping the humid air between the window treatment and the glass.
Reduce Humidity in the Space
Open your blinds regularly to allow air to flow, especially in tricky windows like corner or bay windows. Using a dehumidifier can remove moisture from the air too.
Open Your Window
This might seem obvious, but it's effective. Opening your windows will release the humid air outside, and therefore, will prevent the humidity from collecting onto your windows. So, if it's not too cold out and you're suffering from condensation, open a window.
In the winter, if you have south-facing windows, let the light shine in. The sun will help heat your home naturally, which takes some pressure off your furnace. For other windows, keep blinds and curtains close during the winter to keep heat inside your home.
Closed blinds, regardless of the blind type, help to insulate the window they're on. Some blinds are far better at this than others, but a blind – particularly a very thermally efficient one – can make a massive difference to the amount of heat that escapes via your windows.
By closing the blinds, you keep direct sunlight out of your home and reduce unwanted solar heat gain. Closing window blinds help save energy in the winter since, during cold nights, heat is lost through windows. Closing the blinds will add some insulation to the windows, reducing heat loss.
Window blinds—vertical (Venetian blinds) or horizontal slat-type (louvered-type)—are effective at reducing summer heat gain and reducing glare, while providing good daylight indoors.
While you may be focused on removing the dust in your home, according to an article published in Science Daily, letting the sunshine into your home through the windows can actually kill bacteria that live in the remaining dust and this can help decrease the risk of respiratory issues.
To stop condensation on windows at night try keeping your bedroom door open to improve airflow and leaving your curtains open, or swapping for a thinner material. If this doesn't fix the problem, check the seals of the windows (as mentioned above) or consider running a dehumidifier at night to keep moisture at bay.
