To limit the probability of sagging and misalignment or opening of joints, which could lead to:

  • an inadequate delivery of warm air or return of cold air, or
  • inadequate ventilation.

This is to limit the probability of:

  • an inability to maintain the minimum indoor air temperatures [see Sentence 9.33.3.1.(1)], which could lead to condensation, or
  • inadequate combustion air for fuel-burning appliances.

This is to limit the probability of:

  • the inadequate control of temperatures, airborne pollutants or relative humidity,
  • the generation of pollutants from biological growth or from materials that become unstable on wetting,
  • the deterioration of building elements, or
  • incomplete combustion.

This is to limit the probability of:

  • negative effects on the air quality of indoor spaces, or
  • the inadequate thermal comfort of persons.

This is to limit the probability of harm to persons.
