lining a wooden shed

[Andre FischerParticipant @andrefischer53674]

Hello – seeking knowledgeable shed-heads for sound advice.
I have a 3.50×4.50 metre wooden shed on a concrete base. It's made from 34mm tongue and groove planks interlocked at the corners. Therefore there is no frame.
Going to be used for sleeping visitors and occasional study. At the moment the plan is to line it with first a stapled on membrane,
either, polystyrene/ aluminium sheet 4mm
or, bitumen felt/aluminium sheet maybe 5/6mm
Then plasterboard screwed directly onto the wood through the membrane.
So is this a good idea or could there be problems?
All helpful comments gratefully received and considered.

4mm to 6mm of insulation – why bother? Insulation and lots of it! I'd have thought at least 50mm and preferably 75mm or more of 'Kingspan' insulation or similar and then lined with foil-backed plasterboard. If there's no structural timbers inside, then it can all be fixed with modern building adhesives such as 'No More Nails'.

The thing with the slot together buildings is they shrink and grow in height so you need to fit slotted battens ontop of your breathable membrain otherwise all the plasterboard fixings will pop as soon as there is a change in humidity. If you batten with something like 38x 63CLS and fill between with 50mm Kingspan/Celotex you can leave a slight gap on the outside, then 25mm Kingspan'Celotex over the lot, foil tape the joints and then plasterboard with taped & filled joints.

Quick lick of emulsion and you are ready to rent out to a dozen illigals

Hush your mouth man; you don't know who reads these forums, you'll have 200 outside your door by the weekend… & it's your tax that will be funding the housing benefits they will be getting… so you'll only be getting your own money back… false economy … plus HMRC will be after you for unearned income… they haven't got the guts to go after the big boys… daily rant over … have a nice day

Ok folks thanks.

The poor migrants are all at or on their way to Calais. No work here in France for them. Perhaps a few garden shed for them up there might be a bit more humane than treating them like animals to be kept out of the garden at all costs.

Yea it's the mismatch between ever moving wood and ridged plasterboard that is the problem. On the insulation side, it is more important to keep heat out in the summer than having it cosy, cosy in winter. I've almost? decided to use metal profile for the plasterboard. Even then the top rail will be attached to the wood but I can make it so the screw can move up and down.

Thanks again for your input. As they say many hands make light work.

Also George, A rant a day keeps high blood pressure at bay.
