Chip board

[petesgrayz]

I'm building a timber shed. I've got the framework up and I've put the roof on before cladding the sides.
I've used chip board and roofing felt. The problem is because the sides are open the chipboard seems to be getting damp. I won't be working on the shed until the weekend and the weather forecast is rain. Any suggestions.
TIA

Yes! Strip out the chipboard and replace it with sarking board from your local timber supplier. You'll get condensation under the roofing felt, and as you're aware, wet and chipboard simply don't mix.The sarking board should come pre-treated, and shouldn't cost too much.
