I recently got a shed built after seeing one made by the builder for a neighbour nearby. The one I saw was in good condition and no mould etc. I had the same one built. Wooden frame, concrete floor, plywood and cladding on the outside, GRP roofing and plywood inside on walls and roof. No insulation. Plywood inside was painted with external wood paint. The floor was painted with masonry paint as well.
I am now seeing mould appear on mine (not sure why neighbour was not getting it as the only difference between his and mine is the paint) and having done research now, think some sort of insulation, airflow, vapour barrier etc is needed.
Could some experts please advise on how I can get the builder to fix it?
I have done some research on these forums so some points below.
1) Celotex or Rockwool insulation? I read somewhere that Celotex is not suitable for sheds but have seen some people use it. Any links to products I can use would be appreciated
2) Do I need to leave an air gap or fit the insulation right up to the cladding
3) On the inside, do I need a vapour barrier on top of the insulation as well? Something like this https://www.toolstation.com/green-vapour-barrier-125mu/p86538
4) Are any air vents needed?
5) I guess the mouldy wood panels on the inside have to be thrown away and new ones used? I can't just use a mould cleaner to clean them (although mould on the surface is removed easily. Just spray and wipe down)
Lots of questions but I am attaching some pictures. I wanted to keep this shed weatherproof and use it for storage so thank you in advance for any suggestions or advice.
