The Causes of Condensation

Posted on 13/01/2016 in Condensation

Normal air contains moisture, which is water vapour and warm air can hold more water vapour than cold air. When moist warm air comes in contact with a cold surface, such as a window, a cold wall or a ceiling, the water laden air can no longer hold the water and droplets form on the cold surface. Technically this is the dew point of water; which we see as condensation.
