If you're living in the UK, you're no stranger to window condensation issues. The ever-changing weather, with the combination of rain and humidity, often leads to pesky water droplets forming on your windows, especially in bathrooms and washrooms. Not only can window condensation affect the aesthetics of a property, but it can also lead to more serious issues such as mould growth and damage to your window frames.
There are, however, plenty of things you can do to reduce window condensation, whether that be in your home or office.
What is condensation?
Condensation is when the moisture in the air transforms into water droplets on a cooler surface. It happens because warm, moist air holds more water vapour than cold air. This means that when the warm air meets something cold, for example, a window, it cools down and the moisture in it becomes tiny water droplets sitting on the surface.
What causes condensation on windows?
Condensation on windows is caused by the difference in temperature between the indoor and outdoor environments. When the air inside your property is warm and contains moisture, and it comes into contact with a cold window, the following happens:
- The warm, moist air touches the glass
- The air near the window cools down
- The excess moisture in the air turns into tiny water droplets
- These water droplets form condensation
How to stop condensation on windows
To stop condensation on bathroom windows, you can take several steps to manage indoor humidity and improve insulation whilst also creating a comfortable environment for living or working.
- Improving ventilation: Proper ventilation is crucial to reduce humidity levels inside your home. Ensure rooms such as bathrooms have fans or open windows to let out moist air, especially when showering or having a bath.
- Double-glazed windows: Double-glazed windows create an insulating barrier between the indoor and outdoor air, reducing the temperature difference and minimising condensation.
- Seal gaps and cracks: Check for any gaps or cracks around your windows and doors. Properly sealing these openings can prevent cold drafts.
- Dehumidifiers: A dehumidifier can be an effective tool to control indoor humidity levels. Run a dehumidifier in rooms prone to condensation, especially during the colder months. These are also brilliant for creating comfortable, clean environments.
- Use anti-condensation products: There are various anti-condensation products available, including window film, which can help reduce condensation on your windows and also reduce dampness around the space.
- Regularly wipe down windows: During particularly humid periods, you may need to wipe down windows with a dry cloth to remove condensation. This can prevent moisture from causing damage and collection of mould.
The issues of condensation
Condensation can lead to several issues, especially when it occurs frequently or in large amounts. Common issues that can be caused include reduced visibility, mould and dampness, window and room damage, poor air quality, reduced energy efficiency, odours and dirt collection, cracked surfaces and effects on the aesthetics of a space.
