With my floor joists exposed I've realised that I can't just lay fermacell flooring straight down onto the joists. A 'sub floor' is required first.
From reading the wiki and other peoples posts here it is clear that MDF or chipboard won't do. My alternatives seem to be replacement floorboards or plywood. I don't like floorboards so my plywood questions are ...
Do my joist centres decide the plywood thickness I must use ?
Must the plywood thickness be 18mm or do regs allow me to go thinner?
What is marine plywood ? Is this what I should buy ?
Is there something obvious I've overlooked ?
Thank you.
