condensation how i understand it is warm air rising, hitting something colder than it cooling the air rapidly forcing it to turn to water....

the way i understand how this will now work is the air will rise sure, but instead of hitting cold tin it will hit warm insulation and not condense hence not acctual condensation.


to back up my theory even more i've had an oil rad in the garage over the last 2 nights and got rid of the condensation completely.. but that is a 1.1kw oil rad left on for 48 hours to get to that stage... this insulation should mean i only need to put the heater on for a few hours over night to keep the chill off the insulation
