Description

The need for dwangs, those horizontal blocking pieces used between wall studs, has lessened over the years. Using fewer dwangs and making them narrower than the studs could improve a building’s thermal performance.

The use of Dwangs (also known as nogs or nogging in some parts of New Zealand) has evolved as light timber-frame construction methods have changed. It is interesting to look at how our use of dwangs has evolved and how we have arrived at the current situation for use of them.

Scope

  • Dwangs first used here in the 1920s
