So we have 2 sheds - 1 for all the garden & tools stuff/duck feed and bedding/bird food and the other one is my office/man cave.
Its just over 2 yrs old, has been treated and painted twice once we got it. During the Christmas break I fitted corrugated sheeting on the roof (on top of the felt) as some water was getting in under the felt as a result of the winds and amounts of rain.

However, I am thinking of trying to insulate the shed (wall and roof panels) but I am aware that I have to watch out for condensation/wood breathing etc. I am aware that I could go to the usual search engine and see what the hits there say but I thought that I'd check for any personal experiences too.
Has anyone ever insulated a shed?
If so what with?
Any advice would be gratefully received.
How did you get on?

If it was me, I'd line the inside of the walls with sheep's wool, then cover it over with sheets of OSB. I'd put ventilation grilles at the top and bottom of the OSB to allow some airflow and prevent damp. That would be cheap and cheerful, whilst also providing homes for countless wood mice

Yup wool not rockwool but wool. Best natural insulator there is cheap and getting back to popularity again.

Yup. I reckon you could get hold of it for about £1 a fleece. That's my final offer though - I refuse to pay you any more than that to take it off my hands!

You are right to consider condensation risk. The normal method (e.g. in a house) would be to have an inside lining, insulation, vented cavity, and outer wall. The first cold surface encountered is the outer wall, and the ventilated cavity deals with the condensation.
Alternatively you go for 'full fill' insulation where you leave no voids or cavities anywhere. That makes the outside wall the first cold surface, and condensation there simply doesn't matter.
