Intent

Intent 1:

To limit the probability of:

  • precipitation or meltwater ingress at the heads of openings through cladding, and
  • an inadequate dissipation of precipitation or meltwater to the exterior, which could lead to the excessive accumulation of moisture.

This is to limit the probability of deterioration, which could lead to compromised structural integrity of exterior walls or elements protected by exterior walls, which could lead to harm to persons.
