    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 ?

    Ta

    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.

    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.
