4m x 5m Timber Shed - Can I put metal/Plastic/composite sheets over existing wooden cladding?

[stummbla]

I want to add metal/plastic or composite(depending on price) cladding to the 4 external sides of my shed to cut down on painting/maintinace each year..Can I install sheets to each side of the shed by just attaching them directly onto the existing wooden cladding? or do I need to use battons, create an air space and install vents to the sheets to prevent damp?
The wooden shed has 18mm shiplap cladding on the outside already
Thanks In advance!

As long as it fits under the roof you can add external cladding.

I did it to mine using something like this. I got it in Homebase, I think it was aboput 8ft x 4 ft and 8mm thick. I did it a couple of years ago and, it only took an hour or so. I have painted it with the same stuff I used for the wood.
