gfs1

Question for the boarding guru's.  Stud wall at 400 centres, likely to have backer boards attached in shower area.  Can I use gfs1 for supporting edges, and mid board support instead of cutting up noggins?  I could use thicker backer boards but have scrounged some gfs1 left over from metal framing that went up at work.

Being a bit OCD I used to support board to board edges not over studs with scraps of ply or timber, don’t have to be noggins (IMO).

I've seen board to board edges screwed and dabbed together with bits of offcut plasterboard plasterboard and adhesive before.
