I am re-doing a en-suite and am sorting out flooring at the moment. I currently have a T&G chipboard floor nailed on joists. Karndean recommend installing a Plywood to comply with warranty of product and I was going to do this anyway because of it being a wet area.
I am therefore going to lay a WBP plywood floor on top of this but was wondering what thickness would be best? I would prefer 6mm as this wouldn’t hinder my current floor level too much but having looked at B&Q this afternoon this does seem somewhat flimsy and wondered if it may be beneficial to go for a 9mm or 18mm thick plywood instead?
I have a bit of movement in the chipboard T&G boards currently which I am going to look at securing – If I was to opt and secure a thicker Plywood say 9mm or 18mm and screw through joists I feel that this may eliminate any movement below, obviously I will try and eliminate any movement as best I can in the chipboard prior to commencing with anything.
