Objective:

APPLICATION:

Performance criteria and installation methods for materials, components and their connections, for which a standard is listed in Table 5.10.1.1.
This applies to building materials, components, assemblies and their interfaces described in Sentence 5.1.2.1.(1) that are installed in buildings to which Part 5 applies [see Sentence 1.3.3.2.(1) of Division A for application of Part 5].
This also applies to cladding assemblies installed on buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9] where:
  • the cladding assembly is not addressed in Section 9.27., or
  • the cladding assembly does not comply with the prescriptive requirements of Section 9.27.
This also applies to the position of low air and vapour permeance materials within the building assembly relative to the position of materials providing thermal resistance in the assemblies of buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9], where the building assembly:
  • incorporates low permeance materials that act as other than cladding or that are installed on the warm side of the assembly, and
  • is more susceptible to condensation [see Sentences 9.25.1.2.(4) and (5) for combinations of interior and exterior environmental conditions that create a higher risk for condensation].
This also applies to the design of vapour barriers in buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9], where the building assembly is more susceptible to condensation [see Sentences 9.25.4.2.(2) and (3) for combinations of interior and exterior environmental conditions that create a higher risk for condensation].

INTENT:

To limit the probability that the performance of materials and components and their installation will fall significantly below expectations, with respect to:
  • their resistance to:
    • condensation,
    • excessive heat transfer,
    • precipitation ingress,
    • the ingress of moisture from the ground,
    • the ingress of water from the surface, or
    • air infiltration and exfiltration, or
  • the emission of gases from improperly constituted or applied material (CAN/ULC-S705.2).
This is to limit the probability of:
  • the inadequate control of temperatures of interior spaces, drafts, relative humidity or water accumulation,
  • the generation of pollutants from biological growth or from materials that become unstable on wetting,
  • deterioration, which could lead to further compromised integrity of environmental separators, or
  • pollutant ingress, including soil gas, combustion products from parking garages, or particulates.
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.
