Intent 1:
To limit the probability that thermal insulation
will be exposed to water or be physically damaged, which could lead
to compromised thermal resistance, which could lead to excessively
low temperatures of interior surfaces or within assemblies.
This is to limit the probability of condensation, 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 assemblies acting as or protected by environmental separators.
This is to limit the probability of:
- negative effects on the air quality of indoor spaces,
and
- the inadequate thermal comfort of persons.
This is to limit the probability of harm to persons.
