To nog or not to nog...

Hi all

 

Ive just laid some 22mm p5 grade chipboard over timber joists, 400mm centres, glued and screwed. Im reading conflicting info about whether i need to nog where the board edges are not on a joist?

 

ive been told that if id cut every board to fit on a joist that would have been ideal, sounds obvious now but it my first time and ive dropped a clanger not doing that : (

 

as far as i can see NHBC standards say all short edges should be nogged

 

Anyone had direct experience of this?

 

thanks

Can unsupported joins be a cause for eventual squeeking/creeking? I am sure that's what happened above our lounge as, with the ceiling down, that appears to be the case in a couple of places. I haven't retrofitted some noggins yet but I am expecting (hoping) they will cure it once both boards are screwed down to it.

Not if everything is glued together and that includes the boards to the joists.

I always land short ends on joints. Lmow another chippy who was made to go and not underneath with some h section shape nogs by labc warranty. Learn from others mistakes. Probably nessecary and probably be fine but not hard to do
