Bouncy 1st Floor Joists?

[ashthekid]

I’ve noticed a bit of bounce in two rooms upstairs during our build project and am thinking would doubling up on noggins between the joists help to stop or reduce this bounce? Chipboard flooring has been laid and screwed in. Nothing has been added to the joists underneath yet so that’s why I’m asking now while it’s still possible to up the noggins number. 

What else could be done?

Noggins won’t help. Are they proper joists or posijoists

If you are able to still get at the underside of the floor 

Adding a couple of extra joists would help

They are proper joists. 
Ok so extra joists over extra noggins then?

the joists are pretty close together already, I would say less than 400mm on some of them. It’s an odd shaped property, not that that should make a difference.

If that’s the case There should be any bounce Unless the joists are all over the place
