9.27.6.1.(1)

Intent 1:

To limit the probability of an inability to hold fasteners in place, inadequate watertightness or an inability to resist gravity loads and lateral wind loads, which could lead to 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.
