Did the spec Joist size and distance apart ? Maybe the the joist have to be min 50mm apart ? lol
They did not ask about the joist distance I just said I had a hight issue and one of there reps had told me I could use 9 mm ply and 10mm wedi and they said no it would have to be a minimum of 12mm ply and 10mm wedi and that is as good as 18mm ply.
