Intent 1:
To limit the probability of inadequate moisture
protection, which could lead to an unacceptably high rate of surface
corrosion, which could lead to a loss of strength, which could lead
to an inability to resist expected gravity loads.
For construction that supports environmental separators, 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.
