Intent 1:
To limit the probability of inadequate clamping
or tear resistance at overlapped joints, which could lead to an inability
to resist expected wind loads, which could lead to damage to the membrane,
which could lead to:
- precipitation ingress, or
- excessive air infiltration or “wind-washing,” which
could lead to condensation or excessive heat transfer.
This is to limit the probability of
the failure of required environmental separation elements, which could
lead to:
- compromised thermal performance of components intended
to resist heat transfer, which could lead to an inadequate control
of the temperature 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.
