Hi all. I have one of those metal sheds from Argos, condensation first couple of years was dreadful, the colder the weather the more icicles would be hanging from the roof, thousands of them. I have a timber floor so when they melted onto the floor the cycle started all over again, the answer insulation and i think most important ventilation around the bottom and top of the shed, the building has to breathe, problem solved.
