I need to construct a partition 2.4m high across a 4m run, which is free at the top ... ie a high ceiling with a space above the partition.
I have not built one of these before ... can anyone advise on any extra measures I need to take for extra rigidity or intermediate support?
I am thinking 63x36 timber, normal spacing, and perthaps extra noggins. DO I eg need a joist across the top?
Cheers
Ferdinand
