Intent 1:
To limit the probability that an inadequate type,
length and number of fasteners will be used, 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.
