Hello, this is my first post on the forum so please be understanding.
I bought a 3x5m tin garage, I would like to insulate it with polystyrene soon and put a panel board on it, the garage will be heated occasionally.
My question is whether there must be a space between the sheet and polystyrene?
And if I insulate such a garage, the water will not condense in it?
