Stud wall in archway

[Danny2022]

I am planning on putting a stud wall in an archway to seperate the living and dining room. The archway is 160mm wide. I will be using 12.5mm plaster board on either side and skimming over to finish.

CLS timber seems to either come in 89 or 140mm width. Obviously if i went with 140 it wouldn't sit flush with the wall as it woukd protrude out, if I went with the 89 it wouldn't be wide enough.

What options do I have? Different timber, thicker plasterboard, double up the plasterboard, make one side flush and plaster the whole other side to make it flush? Any help greatly appreciated.

Thanks

Your options are the ones you've mentioned!

I haven't done any of the above before so wondered if there was any recommendations/ pros and cons etc.

If the PB is 25mm in total and the plaster is 5mm? That's 30mm?
So you have 130mm to fill.
Either cut the 140mm down or get some other timber shut down to less than 75mm and use one on each side

89 x 38 CLS, then a 63 x 38 CLS to the side of it and fitted sideways, that gives you 127mm

Then your 2 x 12.5 boards = 152mm

Then 4mm skim each side = 160mm
