Intent 1:
To limit the probability of an inadequate nail diameter
or head size, 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.
