Joists for suspended plasterboard ceiling

Hi Guys,

I need to create a suspended ceiling approx 25cm below the original. The span is approx 1.5m. Stud wall on one side, Solid brick on other

Any pointers on what size timbers I should use? I was thinking of 3" by 1" as it just supports the plasterboard ?

Also i any suggested way to attach them to the walls ?

3" x 1" sound good to me.

plug and screw it to the wall.

use 4" 10's or 12's with brown plugs and a 7mm drill bit.

 

RE: Attaching to wall.

May be easier to have a wall plate (2"x4" ought to do it) of some sort at each end of the wall, make it easier attaching the timbers to.

 

Thank chaps

re. the wall plate, sorry to be dumb, but do the joists hang under this - and just screwed up into it ?

basically, fix a timber all around the room, then fill in between at 400mm c/c at the same height as the wall fixed timbers.

orientate the infill timbers so that they run the shortest span.

 

gotcha - thanks very much
