Intent

Intent 1:

To limit the probability of unprotected joints, which could lead to silting-up of drain tiles or pipes, which could lead to excessive moisture loading on foundation walls and basement floors, which could lead to:

  • 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 the temperature of interior spaces, relative humidity, or water ingress and 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 elements protected by the 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.
