Metal shed insulation

    I am going to insulate a steel shed with 50mm Kingspan panels and finish with plywood sheets. My question is should I adhere the insulation to the metal sides or to the plywood or does it make a difference?

    Hi just wondering if you ever insulated your shed after? and if you stuck it to the metal sheeting or plywood? 

    i am insulating a metal shed myself at the moment i am keeping the kingspan tight to the metal box profile cladding leaving no cavity gap between them and i am now in two minds wheter this wll cause thermal bridging and have mold in a later time on the osb board wich i am going to sheet the shed out with?

    I'm not sure how its done exactly in your shed, but I suggest putting a layer of vapour barrier between steel and foam, and if you can maybe another layer on inside of foam facing inside of shed.

    I got an insulated steel shed built and it came with 2 layers of membrane fitted as described above. It was probably glued to steel in factory etc. The sales rep insisted of this (well that's how they build their sheds anyway) as it will prevent damp absorbing into foam from the steel side of foam.

    food for thought.
