Where does most water vapour come from ?
The most common sources of water vapour are cooking, drying clothes on radiators, washing up, indoor plants, moisture from newly built houses and extentions, and from the breath we exhale. Astonishingly, the average family creates up to 20 pints of moisture every day, simply by washing, cooking and breathing. Two sleeping adults extrude two pints of moisture in 8 hours, which is absorbed as water vapour into the atmosphere. This moisture must go somewhere and be dealt with to avoid condensation. Where can condensation occur ? Due to the thermal currents within a house, condensation can occur in a number of places, usually at cold spots i.e. a room or conservatory without adequate heating. Condensation forming on the room side surface of a sealed unit indicates high water vapour content present and inadequate ventilation. How can I reduce condensation ? Condensation will take many forms, the most common being steaming windows and, when worse, puddles of water on the window cills. In ext
