Structafloor/subfloor laying question 3600x800 sheets.

Hi -

When laying 3600x800 sheets to the perimeter of the building with joist spacing at 450crs the end of the sheet doesn't land on a joist spaced at 450 (unless you center the joist to the perimeter beam) what would you normally do here, put in another joist @ 3640 so the end lands centre to that joist, but then your spacing becomes 50mm out of whack for that one.

Obviously I want to avoid cutting the sheet back to the nearest joist.

Thanks!

You need to cut your sheets and stagger them if that makes sense

As above, you will need to trim your sheet to land on the joist, also make sure you are running your length at right angles to the joists
