Intent

Intent 1:

To limit the probability of an inability to accommodate dimensional changes due to variations in moisture content, which could lead to jamming of sheet edges, which could lead to buckling of cladding.

This is to limit the probability of precipitation ingress, which could lead to deterioration, which could lead to compromised structural integrity of the wall or constructions supported by the wall, which could lead to structural collapse, which could lead to harm to persons.
