Intent 1:
To limit the probability that the performance of
form material for use in flat insulating concrete form foundation
walls will fall significantly below expectations, which could lead
to:
- the dislodgement or failure of form material,
- the excessive sagging and misalignment or opening of
joints,
- excessively low temperatures of interior surfaces or
within assemblies, or
- an inadequate resistance to air and moisture transfer.
Where elements support or are part
of an environmental separator, this is to limit the probability of:
- condensation,
- rainwater ingress,
- the ingress of moisture from the ground, 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
- compromised integrity of elements supported by foundations,
which could lead to the deterioration of building elements.
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.
