Intent 1:
To limit the probability that the placement or amount
and spacing of horizontal reinforcement will not be adequate:
- to ensure the reinforcement is encased and bonded to
the concrete, or
- to limit cracking due to temperature changes and shrinkage.
Where elements support or are part of an environmental separator,
this is to limit the probability of:
- condensation,
- rainwater ingress,
- the ingress of moisture, or
- compromised thermal performance of components intended
to provide resistance to heat transfer.
This is to limit the probability of:
- an inadequate control of temperatures of 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.
