Intent 1:
To limit the probability of an inability to accommodate
dimensional changes due to variations in moisture content, which could
lead to jamming of sheet edges, which could lead to buckling of cladding.
This is to limit the probability of the displacement or
failure of required environmental separation elements, which could
lead to:
- precipitation ingress, or
- compromised thermal performance of components intended
to resist heat transfer.
This is to limit the probability of:
- an inadequate control of temperatures of interior spaces
or water accumulation,
- the generation of pollutants from biological growth
or from materials that become unstable on wetting, or
- deterioration, which could lead to further compromised
integrity of environmental separators.
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.
