Intent 1:
To limit the probability that fasteners will deteriorate
at an unacceptable rate, which could lead to the premature failure
of fasteners.
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), to limit the probability of an inadequate resistance
to lateral loads, which could lead to racking of exterior walls.
This is to limit the probability of:
- the deformation of the building, or
- 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 compromised structural integrity
of exterior walls or elements protected by exterior walls, or
- falling cladding components.
This is to limit the probability of:
- the space being unsuitable for its intended use,
- compromised operation of windows and doors, or
- damage to the building.
