Attribution
[F81-OH1.1,OH1.2,OH1.3] Applies to elements that support or are part of an environmental separator.
Application
Application 1: 
Removal of wood debris from soil, in unexcavated areas under buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9], where termite infestation is known to be a problem.

Intent
Intent 1: 
To limit the probability of termite infestation, which could lead compromised structural integrity.
For environmental separators or elements protected by environmental separators, this is to limit the probability of the excessive movement or deformation of walls, which could lead to:
  • the excessive deformation or displacement of cladding,
  • compromised air barrier systems, or
  • compromised thermal performance of components intended to provide resistance to heat transfer.
This is to limit the probability of:
  • condensation,
  • precipitation ingress, or
  • the ingress of moisture from the ground.
This is to limit the probability of:
  • an inadequate control of the temperature 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 compromised integrity of environmental separators or of elements protected by 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.
