So I'm about to put a metal stud partition wall into my utility room which is a converted garage itself.
The existing walls are plasterboard (I think this is called drywall in the states..) the South facing wall has vertical wooden battens every 530mm, behind these battens is a brick wall, with a cavity that is approx 170-200mm deep.
Battens run across the ceiling following on from the ones in the wall.
On the North side there are battens again, but in line with the ones from the opposing wall.
None of these battens are in a suitable place for the partition (on the North wall is the main fuse box for the house, which can't be moved).
My question is - can I fix a metal C-stud directly to the plasterboard using snap toggles or screw toggles? I've discovered these are incredibly strong fixings and for the ideal position would be maybe 30mm from the wooden stud. Or, do I have attach the C-stud directly to something more solid? If so, why? Maybe there are forces put on to the fixing that I hadn't though of.
