Hello @Bondy2
I'm afraid condensation will occur on the shed's metal walls with or without the insulation. To give the Earthwool a bit of protection from the dampness, I suggest putting in some builder's plastic as a buffer between the steel wall and the insulation. In this way, should the steel wall begin to form condensation, it will not seep into the insulation but will instead drip down the wall. There should always be a way for the condensation to escape, this will prevent water from pooling inside your wall.
Let me call on our experienced members @TedBear and @JoeAzza for their recommendations.

Hi @Bondy2,
Just so you're aware, the Ametalin 1370mm x 30m VapourTech Brane VHP Vapour Permeable Wall Insulation is a permeable vapour barrier and does not include a silver face but does have a correct directional facing. You'll find "This side facing out" printed on the product.
The benefit to this product over a traditional silver-back sarking, is through the use of VapourTech®Brane® technology or potentially black magic, water vapour can travel through the insulation to the outside, but the water outside can't travel inside. This helps prevent the build-up of condensation within the structure as very high levels of water vapour are allowed to absorb and diffuse through the core non-woven structure. Silver-backed insulations are vapour impermeable and won't assist in dissipating any internal levels of trapped water vapour, which can become a huge problem inside a small insulated steel box.
Please let me know if you have further questions.

Hi @Bondy2,
I'd suggest using Pryda Foil Fix - Strip of 10. They provide a larger surface area than clouts or staples to prevent tearing.
Please let me know if you have further questions.
