Condensation forms when air which has invisible moisture within it caused by evaporation cools, the warmer the air the more moisture can be contained within it. Many examples..........When you open the upright freezer door a slight mist appears, this is the meeting of the warm moist air within the house being cooled by the cold air falling out of the freezer, the moisture in the warm air is condensing (turning back from a gas into a liquid). When the same air comes into contact with other cold surfaces such as your walls the same happens. Clouds form in exactly the same way, the warm moist air around us rises (for various reasons) and as it rises it cools and when it has cooled enough (reached its dew point) condensation occurs. If there was not as much moisture in the air in your house the problem would not be as bad as it is. This has been mentioned already, cooking, bathing, showering, clothes drying etc. these things cannot be avoided. Air circulation - to remind you we have 24 inch stone walls. We do all our cooking and heat our house with a Yorkshire Range (Yorkshire Range Company in you guessed it Yorkshire) we also have a large open fire in our lounge, these open fires create substantial air flow all around the house, they would not burn correctly without this air flow. This air flow in turn takes away the moist air created by living in the house. Still wish I had insulated the walls downstairs. When you go ahead with insulating you walls if you have concrete floors that have not already been insulated these should be dug up and 4 inches insulation installed.
