Options for shed interior walls

dazzday

Hi Folks,

I cuurently have a 20x20ft shed which is blocked halfway and then sheeted. There is a 6cm gap all round between the block and sheeting start - which kept the shed well ventilated when used previously as a turf shed. I have some netting over it just to stop birds getting in,

However i have now moved some gym equipment out to the shed and find that the equipment is starting to rust due to the rain and moisture getting in (and probably lack of use!)
Im considering adding plyboard all the way round the shed walls up to the wooded beam supporting the bottom of the sheeting - but unsure if its the right solution.

Any suggestions to wind/rain/moisture proofing the shed - while keeping it relatively warm and ventilated?

Fine Cheers

Not sure what difference the plywood will make ?
60mm is a fair gap and can understand why but the cladding seems to stop short and perhaps should go further down or the blockwork higher up. Is there any rain getting in at that location ?
Have you any plans to insulate or heat ?

Depending on wind/rain direction I am seeing rain come in - and out in West it can be quite heavy.

The plywood boards (4x8 boards so would leave a bare block row at the bottom) was an idea in to essentially block the gap whare the rain could come in - like the sketch below. It would also probably look better then bare block.

No real plans to heat or insulate at the moment - but would review the options as its pretty cold out there in the winter.

The first thing you would be better doing is raise the Blockwork, Is it plastered on the outside.?

You need to weather proof it before you start putting finishing things on the inside, if your plywood is getting wet then it wont last.
I would brick it up but then you also need to divert the water thats running down the sheathing away from the bricks or its going to soak through, which depending on what you want from the shed may or may not be an issue.

You need to block the rain from coming in from the outside.

If you block on the inside you'll have exactly the same interior moisture to deal with, in a slightly different place.

It probably isn't just wind borne rain, it's probably also rain running down the sheeting and then getting blown inside.

Obvious question: do you have guttering and downpipes?
