Intent 1:
To limit the probability of inadequate drainage,
which could lead to water penetrating the interior surface of solid
masonry walls, flowing along the interface of the sheathing membrane
material and the interior surface of the masonry, and collecting in
the wall.
This is to limit the probability of:
- precipitation or meltwater ingress, or
- compromised thermal performance of components intended
to resist heat transfer.
This is to limit the probability of:
- an inadequate control of temperatures in interior spaces,
relative humidity 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.
