Hi all,

Slab is down and laying a 15mm plywood subfloor that is to stop 10mm from the slab edge. I have a set of 4 door Bi-Folds that I am installing and was wondering wether they go on top of the 15mm plywood subfloor with the T&G floor butting up against it or do I install the T&G floor on top of the subfloor and then the doors on top of that?

Also either way the subfloor and floor will finish 10mm from the concrete edge so do I need to brace the sill overhang from below?

Thanks

Frank
