Sorry to hijack your thread a little Buffman. But I’m at the last knockings of my own, insulation all in and first fix electrics done, now I need to clad the internal walls with something… and tbh I’ve pretty much run out of money for this.
Original plan was to use birch ply, but at £90 a sheet nowadays it’d be £1000 plus to do. I don’t really fancy dry lining and having to fill & paint, then mess about with plasterboard fixings whenever I want to fix anything to the walls.
So I’ve settled on OSB smartply. I quite like the finish (wife doesn’t but it’s not her shed), and it should be less than £200 to do the lot.
Question though: is 11mm enough or should I go for 15mm instead?
