Sentence 9.27.3.5.(2)

Intent 1:

To limit the probability of inadequate clamping or tear resistance at overlapped joints, which could lead to an inability to resist expected wind loads, which could lead to damage to the membrane, which could lead to:

• precipitation ingress, or
• excessive air infiltration or “wind-washing,” which could lead to condensation or excessive heat transfer.

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