Intent 1:
To limit the probability of inadequate anchorage
for fasteners to resist:
- gravity loads and lateral wind loads, or
- where panel-type siding is installed as bracing to satisfy Subclause 9.23.13.1.(2)(a)(i) and Clause 9.23.13.6.(1)(a), lateral loads,
which could lead to racking of exterior walls.
This is to limit the probability of
the displacement of cladding, trim and flashing, opening of joints
or failure of caulking, which could lead to:
- precipitation or meltwater ingress, which could lead
to deterioration, which could lead to the structural failure of exterior
walls or elements protected by exterior walls, or
- falling cladding components.
This is to limit the probability of harm to persons.
