Attribution

[F61-OH1.1,OH1.2,OH1.3]Applies to elements that support or are part of an environmental separator.

Intent

Intent 1:

To limit the probability of discontinuity in dampproofing and waterproofing materials at form ties, which could lead to an inadequate resistance to water.

Where elements support or are part of an environmental separator, this is to limit the probability of:

  • 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
  • deterioration, which could lead to compromised integrity of elements protected by foundation walls.

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.
