Intent 1:
To limit the probability of:
- inadequate protection of the insulation, air barrier
system or vapour barrier, or
- where the interior finish contributes to the required
bracing, the inadequate performance of the interior finish, which
could lead to an inability to resist expected lateral loads, which
could lead to excessive racking.
This is to limit the probability of
the failure of required environmental separation elements, which could
lead to:
- condensation,
- precipitation ingress,
- pollutant ingress, or
- compromised thermal performance of components intended
to resist heat transfer.
This is to limit the probability of:
- an inadequate control of temperatures, drafts, relative
humidity or water accumulation in interior spaces,
- 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, or
- contact with moisture.
This is to limit the probability of harm to persons.
