I am having a small extension built, the flat "warm roof" joists are hung from 3 timbers (190mmx45mm) bolted together in place in a wall slot, then hangers attached and the joists attached.
The joist spacing is 450mm and the span 3mtr.
To stop the joists twisting over time and ruining any ceiling what would be the recomended spacing for noggins assuming they are of the same timber as the joists?
