Plasterboarding a hip

[MortarThePoint]

Is there an easy way to secure plasterboard at the hip line of roof rafters? I have mineral wool insulation between and below the rafters. That means I have battens running perpendicular to the rafters which the plasterboard can be screwed to. But at the hip corner the plasterboard joint will need supporting.

 

I can think of cutting a v-shaped trench in a piece of 4x2 and attaching that to the hip rafter, but that's a bit tricky. I'm hoping there is a simpler solution.

Otherwise just some plasterboard corner tape could help.

Most of what are pictured are external render beads You can make the internals up in timber and simply board and use a skim stop on any eternals

Internal corner. So would you cut a v-shaped trench in a piece of timber and attach it to the hip rafter?

A picture would help 

I’d avoid using beads on internals 

Just looking to see if I’ve any hips on my phone

That’s closet I can find on my phone 

Prior to being counter battened with 3-1 Exactly the same on an internal Just reversed Your skimmer or taper will do the rest

Yes picture of what you are trying to board onto.

 

It does not matter if the last support of the PB is not right at the edge, it is not that bendy.

 

One of our gable ends (closest we have to a hip) before the counter battens went on

 

And after plasterboarding

These are external corners aren't they, so what you'd have at a valley rather than hip.

Here's where I mean. Photo prior to battens

Is that a warm roof, or do you have insulation to go in first?

That photo is before the insulation went in to fill the rafters up to the black straps (leaving 50mm ventilation under membrane).

Here's the corner now. I've linked the horizontal battens but really need something following the hip line. This is needed for two reasons:

1. VCL taped join needs to be supported 

2. Supporting the plasterboard joint

I'm trying a piece of batten up one side behind the horizontal battens. I'm going to put in sections of batten to fill in between the horizontal battens and screwed to this vertical batten.

 

It would be so much easier if you could get a bit of metal frame that was like L-channel but had the necessary hip angle.
