Attribution

[F20,F22-OH1.1,OH1.2,OH1.3]Applies to elements that support or are part of an environmental separator.

Intent

Intent 1:

To limit the probability of an inadequate diameter, thickness or crown length, or incorrect orientation, of staples, which could lead to inadequate capacity, rigidity or pull-through resistance, which could lead to an inability to resist expected lateral, gravity or wind-uplift loads.

Where wood-frame construction supports or is part of an environmental separator, this is to limit the probability of the displacement or failure of required environmental separation elements, which could lead to:

  • condensation,
  • precipitation ingress,
  • excessive heat transfer,
  • pollutant ingress, or
  • compromised thermal performance of components intended to resist heat transfer.

This is to limit the probability of:

  • inadequate control of temperatures of interior spaces, drafts, relative humidity or water accumulation,
  • the generation of pollutants from biological growth or from materials that become unstable on wetting, or
  • deterioration, which could lead to further compromised integrity of environmental separators.

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.
