Hopefully this is a quick one for the experts out there. I’m building a garden office. Floor joists are in 145 x 45 and will celotex in between. Noggins every 40cm.
On top can I get away with 11mm marine ply or should I really only be thinking about 18mm?
Is there really that much difference?
Thanks.
