Looking at that diagram, I'd say that Strongbacks are as much about dampening vibration, as they are about reducing deflection

good observation - an accurate one I suspect.

@recoveringacademic Ian,  I've just posted separately on this.  Sorry for missing your original post.  My strong recommendation is to put them in now.  Putting them in now as you place your joists is easy.  Joist half way, slide them in; finish joisting and slide back into position then fix.  If your BControl officer says that you need them and you haven't got them then you will have to be cutting holes through the ICF to slot them in from the outside. Uuaaaarrrhhh.

@recoveringacademic Surely if they are needed they would have been specified in the drawings  by the joist supplier?

+1 to that although if I had some 4x2 floating about and the joists have the central blocks then I would fit them as they also make a nice easy central run to take cables down ..!

I didn’t install strong backs in mine but I inserted 4x2 noggins flush with the bottom of the joist to carry the plasterboard edges and stop the joists twisting (not likely with engineered timber).

DWB supply 3x2 and Z Clips for both top and bottom noggins with all of their engineered floors along with enough Egger D4 to bond pretty much everything to everything ..!!!
