I’ve made real progress (finally) with the shed! I got the majority of the insulation in yesterday, and I’ll hopefully get to the stage that I can wire and network next week.
For posterity’s sake I added a DPM attached with contact adhesive to the bricks and run up the wall. I did this as the shed is a single skin brick wall and with a lot of rain it’s possible that water could penetrate this. Normally a cavity wall allows rain to run down the inside of the outside skin.
The insulation was attached using 8mm 120 mm hammer in fixings through a 1×2 batten. With a blob of silicon sealant to preserve the vapour membrane in the insulation. The battens will be used to add t&g paneling when the wiring is done!
For the floor I had 100 mm non-foil Kingspan insulation, followed by DPM, and then 22mm t&g flooring chipboard.
