Angled stud wall construction

[regsmyth]

I am renovating part of our bungalow, and I am dividing one large room into two, with a new stud wall which is neither parallel or perpendicular to the roof trusses.
The easiest way for me to do this is to plasterboard the whole ceiling first, then fit the stud wall top plate up to the underside of the plasterboard. Is this acceptable practice?

Thanks.

This is normal pactice, but before plaster boarding, fit 50x100 noggins betwen ceiling joists for fixings of top plate.

Ah well......
I've actually already boarded, and I'm going to fix the top plate through into each truss.

I did fit noggins (little ones, so as to not cut out too much of the insulation) as I was fitting all the kingspan insulation, to catch the edges of the plasterboard, but I don't think these correspond with where the stud wall will be.

Thanks.

should be fine just fix to as many trusses as you can
