Intent 1:
To limit the probability of inadequate backing support,
which could lead to inadequate strength to resist impact or other
lateral loads, which could lead to the excessive deformation or cracking
of stucco, which could lead to:
- 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,
- deterioration, which could lead to compromised integrity
of exterior walls or elements protected by exterior walls, or
- water accumulation in interior spaces.
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.
