I have a newly created floor (for a loft conversion) that is chipboard over wooden joists with noggins. At present there is no ceiling below it.
Some of the joists have been doubled up due to the span and don’t fit that well together as the timber was not perfectly true. I can also see some gaps between noggins and the joists, once again due to the joists timber not always being true.
There are lots of creaks as the floor is walk on.
However the chipboard is screwed down to all the joists and glued in the tongue and grooves.
Is there something I can easily fill the gaps between the joists and noggins with from below (e.g. some sort of thick flexible glue) that will solve the problem long term?
Will putting screws (as well as the current nail gun nails) in all the noggins helps?
How do I stop the problem coming back after the ceiling has been put up?
