[F20-OP2.1,OP2.3,OP2.4][F22-OP2.3,OP2.4,OP2.5]Applies where panel-type cladding is installed to provide the required bracing.

Intent

Intent 1:

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 inadequate anchorage for fasteners to resist 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.
