Intent 1:
To limit the probability of inadequate moisture
diffusion, venting, or drainage of moisture to the exterior, where
the intended use of the interior space will result in high moisture
generation, which could lead to condensation or water accumulation
within the assembly.
This is to limit the probability
of:
- compromised thermal performance of components intended
to provide resistance to heat transfer, which could lead to an inadequate
control of interior temperatures,
- 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:
- the inadequate thermal comfort of persons,
- negative effects on the air quality of indoor spaces,
and
- contact with moisture.
This is to limit the probability of harm to persons.
