Intent 1:

To limit the probability of the premature failure of fasteners, which could lead to an inadequate bond between stucco and its substrate, which could lead to delamination or cracking under gravity, wind or impact loads, or freeze-thaw stresses.

This is to limit the probability of:

  • precipitation or meltwater ingress, or
  • compromised thermal performance of components intended to provide resistance to heat transfer.

This is to limit the probability of:

  • an inadequate control of temperatures of interior spaces or relative humidity,
  • the generation of pollutants from biological growth or from materials that become unstable on wetting, or
  • deterioration, which could lead to compromised integrity of exterior walls or elements protected by exterior walls.

This is to limit the probability of:

  • negative effects on the air quality of indoor spaces,
  • the inadequate thermal comfort of persons, and
  • contact with moisture.

This is to limit the probability of harm to persons.
