    OSB3 vs Ply vs floor boards - Please help!!!

    Carpet definitely a NO-NO. Bad for asthma/respiratory allergies. Love the exposed pale wood floor look. Pics below. But don't want to do it if it involves too much heavy work(sanding). It will be difficult for me to take the heavy sanding machine upstairs.

    OSB3 vs Ply vs floor boards - Please help!!!

    Does ply contain formaldehyde? Is OSB3 free of formaldehyde? Apart from aesthetics do floor boards have any advantage over ply/OSB? If budget is not much of an issue which one would you choose and why?

    OSB3 vs Ply vs floor boards - Please help!!!

    For aesthetic reasons I like floorboards. For money reasons OSB. For moisture related problems ply seems to be better than OSB. Any other things I should be aware of.

    OSB3 vs Ply vs floor boards - Please help!!!

    If we use OSB then no. We will need other floor covering. If we use ply can we seal it off with 3 coats of polyurethane? Does it need to be sanded? Floorboards are planed and smooth so no need for sanding, right? Just seal it with 3 coats of poly urathene? Do I need to do anything to fill the gaps?

    It also depends on the exposure time, I suppose? But the said member always have to carry an inhaler with them.
