Plasterboard stop bead

[Robin66]

I'm making a feature in my living room that's going to have an exposed plasterboard edge. One face of the plasterboard will be facing into the room and the otherside will not be visible. It will have cladding at right-angles to it, and the plasterboard will be covering the edge of the cladding. I have some 3m lengths of 13mm stop bead from B&Q. I'm not plastering it myself. Which way round shall I place the stop bead? With the flange on the exposed face or on the non-visible side?

Any advice apprenciated

Hello,
you would be better off letting the plasterer put up the beads.
There is nothing worse than working to other peoples beads.
