After my clearly silly OSB idea, I've decided to use Contiboards from B&Q, which is cheaper, anyway. The shelves will be 825 mm long and 200mm wide. I was hoping to use the 18mm thick white boards, but B&Q suddenly seem to be only doing 15mm.
The shelves will be battened on 3 sides, so is 15mm enough?
