As the temperature outside drops, how to stop condensation from affecting your windows becomes a much bigger priority.
But just what is condensation? Basically, air contains moisture, but the temperature of the air determines how much moisture it can hold, and warm air contains more moisture than cold air.
When warm, moist air comes into contact with either a surface or air that is colder than it is, the warm air is unable to retain the same amount of moisture as it did and the water is released either into the cold air or onto the colder surface, causing condensation to form, quickly followed by mould.
What are the Main Causes of Condensation in the Home?
Day-to-day activities such as cooking, washing and drying clothes, heating and even breathing produce water vapour. Air can only hold so much moisture in the form of an invisible vapour, no matter what temperature it is.
When the air contains more moisture than it can hold, it reaches ‘saturation point’ and when this is reached, the moisture turns back into water and condensation occurs. The temperature reached at saturation point is called the ‘dew point’.
When this happens, the air has a relative humidity of 100%. The air in the majority of homes tends to have 50-70% relative humidity. Problems occur when structural defects in a building mean the moisture content has become too high; when old houses have no damp-proof course (DPC) and when there is inadequate ventilation in the home.
Period homes often have no damp proof course, which means moisture from the soil beneath the house rises up into ground floor rooms, whilst other homes suffer from bridged DPCs or damaged guttering.
What Problems can Condensation Cause?
The issues that condensation can cause are often the sign that it needs addressing in your home, and their effects can vary depending on the fabric of your home.
Problems caused by condensation include:
- Timber window frames decaying
- Water droplets on windows, obscuring the glass
- Damp walls where paint and wallpaper may peel
- Black mould on walls, window sills, soft furnishings and more
- Risk of rotting and structural decay
- Potential health issues, especially to the young, elderly and those who suffer from respiratory issues
