Attic Floor

The Fool

Have a modern truss type support in attic, "W" shape.
Had planned to put some flooring in the middle between supports for storage.

Problem is the Joists are 23" appart which seems a bit much for
Chipboard flooring. Not sure there is enough suppport for floor.

Any advice?

thanks

yes this is ok but i would use ply wood rather than chipboard ,ply wood is more stronger , but you if want to use chipboard you can ,its just cheaper . the chippie

Get some lengths of 2x1 and run them at right angles to the joists at the width which suits your chipboard.

you can do that too ,i would use 3x2 instead of 2x1,
18mm ply is just as strong

thanks for the tips, i'll price both and see which works out cheaper

Get unfinished/unplaned wood as it's usually cheaper and look out for warped or damaged pieces that may be on special offer.
