Hi,
I am sure you have all been asked this a thousand times, but I cannot find an answer.
We are building a wooden framed garden office/summer house, using plywood for the walls, and OSB for the roof.
We are then going to externally 'clad' the walls. The roof will have
'Galvanised Steel Roofing Sheets', which I believe I put a plastic sheet/breathable membrane on the OSB then batons then Galvanised Steel Roofing Sheets
The problem I have is that I cannot work out if there is a need for an external vapour barrier i.e underneath cladding, or internal in between the joist, and before I insert the insulation board between the stud work?
My understanding is I need one, but I do not know which one.
Obviously, I want to give as much protection from water as possible, but I don't want to end up with condensation everywhere!
Can anyone help with this?
