Sentence 5.9.1.1.(1)

Intent 1:

To limit the probability that the performance of materials and components and their installation will fall significantly below expectations, with respect to the structural integrity, which could lead to structural failure, which could lead to harm to persons.

Intent 2:

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
  • the ingress of precipitation, water or moisture from the exterior or from the ground,
  • excessive heat loss or gain, or
  • premature deterioration, or
• metallic components of environmental separators being corroded by chemicals in the cellulose (CAN/ULC-S703).

This is to limit the probability of damage to or deterioration of environmental separation elements, which could lead to compromised structural integrity of such elements, which could lead to structural failure, which could lead to harm to persons.
