Intent 1:
To limit the probability that precipitation or meltwater
will splash, soak or pool against the lower portions of cladding,
which could lead to the accelerated deterioration and premature failure
of cladding.
This is to limit the probability
of precipitation or meltwater ingress, which could lead to:
- compromised thermal performance of components intended
to provide resistance to heat transfer, which could lead to an inadequate
control of the temperature 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, or
- contact with moisture.
This is to limit the probability of harm to persons.
