Intent

Intent 1:

To limit the probability that environmental separators will deteriorate at an unacceptable rate, which could lead to their premature failure, which could lead to:

  • condensation,
  • precipitation ingress,
  • 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, drafts, relative humidity or water accumulation in interior spaces,
  • 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, or
  • contact with moisture.

This is to limit the probability of harm to persons.
