Intent 1:
To limit the probability of discontinuous reinforcement,
which could lead to an inadequate resistance to lateral loads or gravity
loads imposed by the glass block's own weight, which could lead to
cracking at vertically aligned mortar joints.
This is to limit the probability of:
- condensation,
- precipitation ingress,
- moisture ingress,
- excessive heat transfer,
- pollutant 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,
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.
