Intent 1:
To limit the probability of excessive corrosion,
which could lead to inadequate support for stucco or swelling of expanded
metal stucco mesh, which could lead to delamination, disintegration
or cracking under gravity, wind or impact loads, or freeze-thaw stresses.
This is to limit the probability of:
- precipitation or meltwater ingress, or
- compromised thermal performance of components intended
to provide resistance to heat transfer.
This is to limit the probability of:
- an inadequate control of temperatures of interior spaces
or relative humidity,
- the generation of pollutants from biological growth
or from materials that become unstable on wetting, or
- deterioration, which could lead to compromised integrity
of exterior walls or elements protected by exterior walls.
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.
