Hello
Im building a shed and would like to insulate it. Ive seen a company called Poshshed who build theirs with tongue and groove cladding nailed directly onto ply sheathing - with a vapour barrier, which is supported by studs which has PIR insulation wedged between them, and then has a layer of tongue and groove on the inside. It must work for them as they charge 5 grand a shed! but im concerned about copying it as there seems to be no ventilation behind the cladding - does it not need it? Is it working on the principle of a cold roof?
