Intent 1:
To limit the probability of inadequate strength
of the base coat to provide support for subsequent coats [as required
by Sentence 9.28.6.2.(1)], which could lead to an inability
to resist gravity, lateral, impact or abrasion loads, or freeze-thaw
stresses, which could lead to the cracking of stucco.
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.
