Intent 1:
To limit the probability of inadequate mortar density,
which could lead to the excessive shrinkage, cracking and premature
failure of mortar joints, which could lead to air or water leakage
at mortar joints, which could lead to:
- pollutant ingress,
- 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,
drafts, 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.
