Intent
Intent 1: 
To limit the probability of inadequate strength or durability of stucco, which could lead to an inability to resist gravity, lateral, impact or abrasion 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,
  • deterioration, which could lead to compromised integrity of exterior walls or elements protected by exterior walls, or
  • water accumulation in interior spaces.
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.
