Intent

Intent 1:

To limit the probability of:

  • inadequate density to resist water absorption,
  • inadequate strength to resist gravity, lateral, impact or abrasion loads, or
  • inadequate resistance to freeze-thaw stresses.

This is to limit the probability of the cracking of stucco, which could lead to:

  • 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.
