Insulation and vapour control timber frame summerhouse

[Nick80]

Hi All

I am in process of building a summer house / mancave; it is constructured out of 6x2 treated timber (pent roof and floor joists) and 4x2 stud work. I have insulated with 80mm celotex between wall studs and 100mm between floor and ceiling joists. On the outside I have lined with 11mm OSB and stapled breather membrane to it.

Before I put the plasterboard up I have read conflicting advice around whether I should staple a vapor control barrier to the studs and joists.

Can anyone advise on best way to do this, I don’t want to do this incorrectly and cause the timbers to rot.

Thanks

vcl stapled to the studs overlap 150mm and tape.

Stops moisture migrating to the cold osb condensing and rotting.
