OSB3 for sub floor

[Adrian80]

Hi,

I was wondering if anyone has used 18mm osb3 sheets for flooring instead of t&g chipboard.

I would have thought it would be stronger, nut not sure what its like for pull out or through.

Was planning on screwing the stuff down with floor board screws, so it can be lifted.

Does it not be t&g make any difference?

Cheers

You can buy t&g osb3 floor panels, and is an improvement over chipboard, but inferior to proper floorboards or plywood.
I wouldn't use plain edge boards for this though.

My main reason for not wanting to use T&G is because i need to get heating pipes in.

I thought i could in essence leave nice foot wide strips as access panels.

my only reservations is that osb3 is a bit rough, i suspect the floor t&g versions are nicely sanded.

Any other ideas? i dont want the expense of using proper floor boards.

I thought OSB3 was t&g.

Just moisture resistant, can be either T&G or square edge.

I Have used osb3 for a floor and it is fine, but if you are not going to use t&g then it won't be the same.
