Truss fixing

[Jack_D]

Good evening,

I am replacing a section of paramount partition in preparation for a shower wall but I have a trussed roof (parallel to the wall but between trusses).

How should I support the top plate of this wall? Reading lots online about not fixing to the chord of the truss. I imagine noggings but how best to fix these to the current trusses?

Thank you

Not my area of technical knowledge but.

Noggings along and fix to that or put a strap ( long wood) over the top along joists fixed, then screw to joists.
That's will hold it all together.

I did think about straddling across 2 or 3 truss chords and using long screws through the void but this would then limit and vertical movement (read that trusses need this?).

I appreciate plasterboard etc will likely be nailed to the trusses, but I cannot find any guidance on any fixing allowed, let alone type etc

Three noggings along the run will suffice, flush with the bottom or the ceiling chords (joists).
skew screw them and its allowed.

Thanks for your input - would you then suggest fitting some slotted truss clips (Simpson style) to the noggings or is that unnecessary and just screw direct?

The Simpson clips are harder to find in the UK it seems which makes me think truss uplift may not be such an issue?

No need. They’d be stable enough probably, even if they were friction fitted, lol.

Sorry, I meant for the wall top plate to the noggings? I did toy with a friction fit between the chords!

Is there an etiquette on what size fixings to use for chord fixing? I see Simpsons list the proper sizes etc so presumably something along the No.6 line would be adequate?
