Intent 1:
To limit the probability of exposure of moisture-vulnerable
interior finishes to water, which could lead to the ingress of water
into wall assemblies.
This is to limit the probability
of the deterioration of interior finishes, which could lead to studs
being unable to resist expected impact, gravity or lateral loads,
which could lead to:
- where interior finishes contribute to the required bracing
or lateral support for studs, the buckling or racking of walls, which
could lead to structural failure, or
- where interior finishes support or provide the substrate
for required environmental separation elements, the excessive deformation,
displacement or failure of such elements, which could lead to further
deterioration, which could lead to further compromised structural
integrity.
This is to limit the probability of harm to persons.
