Sentence 9.27.5.7.(1)

Intent 1:

To limit the probability of an inadequate withdrawal and lateral resistance, which could lead to inadequate support for cladding to resist gravity loads and lateral wind loads.

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.

Intent 2:

To limit the application of Sentence 9.27.5.7.(2) to cladding types other than wood shingles or shakes, where a lesser penetration of fasteners into framing can be justified.
