9.27.7.5.(1)

Intent 1:

To limit the probability of lath not coinciding with the location of fasteners, which could lead to inadequate anchorage for fasteners, which could lead to an inability to resist gravity loads and lateral wind loads.

This is to limit the probability of the displacement of shingles or shakes, 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.
