Real wood floor along floorboards

[mwkenna]

I need to lay real wood along the existing floorboards (not parallel). I have done my research and there is a mixed bag of people who say that you absolutely have to lay a ply subfloor, but then others say that it's not needed if the existing boards don't move.

What do you think guys? Subfloor or no subfloor?

I would definitely lay a sub floor, as an architect, any project I have worked on in an existing building, where we are laying a new timber floor we have always laid a new level subfloor to be confident the new floor won't move.

Start by looking at what the manufacturer suggests.

Do you mean across the boards as along the boards would be parallel?

What would you suggest? Shuttering ply, OSB, chipboard? I was thinking OSB as it would form a good moisture barrier?

Sorry I meant to say not perpendicular. So the planks are following the direction of the existing boards.

Then definitely requires overboarding.

If the floorboards are flat it will be fine. If cupped then sand flat.
