General questions on laminate and tiling my subfloor


I have a medical condition and am highly sensitive to chemicals, fumes etc. I am thinking of putting some used laminate down and if I react to it, then I'll probably replace it with tiles.

I currently have floorboards which are quite uneven. If I put laminate:

1) Should I put fibreboard underlay or plywood. Why choose one over the other?

2) How thick must the plywood be e.g. 6mm or 9mm and so on. Is bigger always better and what will the difference be?

3)In case I later change to tile, in this case perhaps its better to start off with plywood? In this case, how thick should it be and will what will the main difference be in size.

Not all floors are able to be tiled even if you went over it with plywood.
Got to start out looking at the size, spacing, and spans of the floor joist.

As Joe mentioned---we can run a span chart on your floor system ,if you tell us what your floor joist length ,size and spacing----

Laminate needs a flat floor--but not an unusually strong one---more info would help--

And if you are considering tile later on, don't put down thin plywood. It can't be down under tile.
