What Causes Condensation in Cold Weather. Indoor humidity is exacerbated by traditional heating systems such as radiators and fireplaces. During the winter, households are more likely to rely on these traditional heating techniques to remain warm, resulting in increased moisture production and transmission in the air.
Adequately heating your home can help to reduce condensation and damp, so keep temperature levels consistent, especially in those rooms that you may not use often. A heating thermostat can be useful for this. Avoid using paraffin heaters as these tend to create excess moisture.
Increasing the temperature in your room, particularly overnight and in the winter, will prevent the build-up of condensation on your windows and walls. This is because condensation occurs when water condenses on a cold surface.
7. Keep your heating on low. Temperature fluctuations, especially the temperature plummeting around dawn, are very often responsible for condensation forming on windows. Keeping your home's heating on constant at a very low level rather than intermittently can maintain surfaces above dewpoint and stop condensation.
In most cases, internal condensation issues occur because of too much humidity in the room or little to no air circulation. Low internal room temperatures can also create cold surfaces (particularly on windows and exterior walls) which allows warm air to condense onto them easily.
In fact not heating your house through the winter or colder months can cause real issues for buildings, especially if it has been heated previously, flooded or has a lack of ventilation or has damp problems. When the temperature drops, cold air outdoors, can increase the problems with condensation in the home.
This is because the cold makes your property's walls and windows colder, and condensation is formed when the warm air inside your home that contains moisture comes into contact with cooler temperatures, meaning that the gaseous moisture contained in your properties warm air reverts back to a liquid state when it comes ...
The World Health Organisation guidelines suggest 21 degrees in a living room and 18 degrees in the bedrooms, falling lower at night and when you are out. You don't need to keep your home at these temperatures all the time, but you should aim to bring it up to these temperatures at least some of the day.
It makes sense that people want to save on heating cost, but one of the best mold prevention techniques is keeping your heating on. If you seriously want to avoid mold in your home then avoid rooms cooling completely.
Warmer air holds more moisture and only condenses when it comes into contact with a cool surface. Due to this, it is important to keep surfaces warmer. By eliminating the cold surface, it can be stopped from becoming a condensation magnet.
Removing condensation
Make a habit of removing window condensation first thing every morning — when it's at its worst. Use an absorbent paper towel or microfibre cloth to gently scoop and wipe the water off the surface of your windows. Use a fresh towel or a squeegee to dry the pane thoroughly afterwards.
To permanently reduce and even eliminate condensation in your house, you must reduce the amount of water vapor in the air so that the relative humidity of the air in the rooms is within the normal range, between 30% and 50%. You can do this by using a high-performance indoor ventilation system.
Probably the most effective way to tackle overnight condensation is with a Positive Input Ventilation system (PIV). A PIV draws outside air through a filtration system into a central unit installed in your house (typically in an attic). From there, the external air is evenly distributed to every room in your house.
It is also very important that there is adequate ventilation in the room. Open a window or door so the mold spores can escape, instead of staying locked in your home.
Airtight windows and buildings require more active ventilation. your kitchen and bathroom has an extractor fan. This will help prevent moisture reaching other rooms, especially bedrooms, which are often colder and more likely to get condensation. Do not block air-brick vents or ventilators.
Condensation occurs mainly during cold weather, whether it is raining or dry. It does not leave a 'tidemark'. It appears on cold surfaces and in places where there is little movement of air. It can often lead to mould forming in corners, on or near windows, in or behind wardrobes and cupboards.
The first lesson is that warm air can hold more moisture than cool air. We learned that when the warm air touches a cold surface, it rapidly cools and deposits some of the moisture it can no longer carry. This appears as condensation on the surface which, in the home, is usually a window or outside wall.
Opening the windows to reduce damp from condensation
Condensation occurs when humid, warm air becomes trapped in your home and then meets a cold surface, like a window. Opening a window allows humid air to escape from your home, thus reducing condensation.
Condensation happens when your home is too humid and the warm air hits cold surfaces. This leads to the air cooling quickly and forming droplets on nearby surfaces such as walls/windows.
Curtains or internal blinds on windows can increase condensation on the glass by reducing the window surface temperature. This problem can be reduced by leaving the window open a little.
The appearance of condensation between the panes of glass in your bedroom windows, or in any other windows in your home, indicates that the windows are not doing their job properly. The air-tight seal holding the insulating gas inside has failed, letting all the insulating gas out.
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.
During the winter, if you open the window when the outside air is colder than the air indoors, the cold air will come into contact with the warmer air and the level of humidity will fall automatically.
Get a dehumidifier
In contrast to a humidifier, a dehumidifier will remove moisture in your home and absorb condensation.
