9.7.3.1.(4)

Intent 1:

To limit the probability that the storm doors for sliding doors and their components will have:

• insufficient resistance to wind loads, which could lead to the storm door being blown out of its tracks by wind forces, or
• excessive resistance to wind loads, which could lead to the storm door deflecting, which could lead to the storm door becoming dislodged.

This is to limit the probability of sliding doors being damaged, which could lead to ingress of precipitation, which could lead to damage and deterioration, which could lead to compromised structural integrity of sliding door assembly and adjacent exterior wall assemblies, which could lead to harm to persons.
