I'm trying to plan my floor, I'm pretty sure I know which units I'm going to fit which will be from Evo Motion. It says on their website that they expect 15mm floors but does anyone know where is that measured from? I'm assuming it's from the top of any 9mm packing (basically a level base).
I did email them, but like so many suppliers no one got back to me.

Floor Thickness???
Do you have rails, insulation etc.. our units are cut as standard for 15mm thick floor.
How thick is your floor??
