Shiplap looks nice but lets draughts in and has next to no insulation. In storms, rain can blow in through the gaps
but it has wood-to-wood joints which will move about with the weather
unless you keep caulking it like an old boat, and keep it immersed in water, it is never going to stay tight
Thanks for all the replies!
What about this stuff on the outside Breathable Membrane
I'll be using 50mm polystyrene as insulation.
I'll post up a couple of pics of the progress.
If you're going to use boarding, I'd keep it on the inside. Insulate between studs,then vapour barrier (thin polythene sheet) on the inside, then board over this.
If it's just to store the lawnmower and spiders etc. then just clad the outside and be done with.
You still haven't told us intended usage, breather membrane is a posh choice for a mere shed, and not worth bothering with if using polystyrene.
I'm going to use it to store things (not just garden tools), have an some excersise equipment in there and also a place to work on computers (troubleshooting, upgrading etc).
The Wicks Breathable Membrane seems to be the best value so far.
Going in order from the outside - in
Weatherboard
Breathable Membrane
Studs (100mm)
50mm gap (half way into stud)
Polysyrene
Plasterboard
I did consider rockwool but I read at some where that it probably wouldnt be a good idea for this type of construction.
