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.
Before the days of double glazing, wall and loft insulation this humid, stale air would find its escape route through ill-fitting windows and doors, lofts and so on. It would be replaced by fresher, colder air or to you and me - a draught.
Three Important Factors That Cause Condensation:
The more moisture in the air the more likely it is that you will get condensation.
Today, after the introduction of energy saving measures such as draught proofing, double glazing and cavity wall insulation there is no natural escape route for this stale, humid air, which is now trapped inside the home.
As a result, this trapped and stale air only makes the problem worse, causing condensation on windows, walls and poor indoor air quality.
Improperly fitted washing machine - From just one load of washing two litres of water is emitted into the air.
A flued gas heater - which has a flue or chimney to carry the combustion pollutants and water vapour to the air outside the home. An unflued gas heater has no flue and releases the combustion pollutants and water vapour directly into the room. Burning gas always produces water vapour. If there is not enough fresh air circulating in the room, water vapour can cause high humidity and wet surfaces.
Kitchens and Bathrooms - produce a lot of steam and moisture so always ensure you have extractor fans on, use pan lids when cooking, put bath mats down and keep doors closed.
