    "The best type of insulation is kingspan Insulation board
    But is expensive. The most common type is insulation wool but I wouldn't use this in a shed as if moisture gets to it will become damp and start to smell. I would use a cheaper insulation board like polystyrene which is half the price of kingspan"

    "I would say Kingspan insulation board the same thickness as your support timbers or polystyrene boards these can be found at B&Q"

    "Hi, I would use rockwool insulation and I'd ply the inside for neatness and it'll hold the insulation in place,"

    "Best insulation is cellotex insulation boards which can be bought from local timber or builders merchants. Loft insulation is not good for sheds because of the damp."

    "I would recommend that you use celotex, cut the celotex in between the shed batterns."

    "I would personally use a 50mm or 75 mm
    Celotex cut between the rafters
    With a breathable vapour barrier and then board over the top with osb,ply,plasterboard"

    "If it’s just for garden tools and things you would normally store in there, then no it’s not a requirement to insulate. If however you intend to use it as a garden room etc then yes it would be advantageous providing you adhere to a few caveats. No cold spots between walls and insulation, fully boarded out with additional vapour barrier suitable for the job etc....bit more to it than just sticking insulation between studs/joists. Normally something like min 50mm celotex is used along side rockwool and insulation foam where the other two are not an exact tight fit! That’s if you want to do it right. And of course it needs heating etc etc...."
