ATTRIBUTION:

Functional Statement:

F51

To maintain appropriate air and surface temperatures.

F63

To limit moisture condensation.

F41

To minimize the risk of generation of contaminants.

Objective:

OH1.1, OH1.2, OH1.1

 

APPLICATION:

Spray-in-place polyurethane insulation installed to provide resistance to heat transfer in building components and assemblies as well as at interfaces between components and assemblies 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].

INTENT:

To limit the probability that the performance of the installed material, with respect to chemical stability or thermal performance, will fall significantly below expectations, which could lead to:
  • the inadequate control of heat transfer, or
  • the emission of gases from improperly constituted or applied material.
This is to limit the probability of:
  • excessive heat loss or gain, or
  • condensation.
This is to limit the probability of:
  • the inadequate control of temperatures of interior spaces,
  • the generation of pollutants from biological growth or from materials that become unstable on wetting, or
  • deterioration, which could lead to compromised integrity of environmental separators.
This is to limit the probability of:
  • negative effects on the air quality of indoor spaces, and
  • the inadequate thermal comfort of persons.
This is to limit the probability of harm to persons.

INTENT:

To limit the probability that the thermal performance of the installed material will fall significantly below expectations, which could lead to the inadequate control of heat transfer through environmental separators under expected environmental loads, which could lead to condensation.
This is to limit the probability of deterioration, which could lead to compromised structural integrity of the separators or of elements supported or protected by the separators, which could lead to structural failure, which could lead to harm to persons.

APPLICATION:

Spray-in-place polyurethane insulation installed to provide resistance to heat transfer in building components and assemblies as well as at interfaces between components and assemblies 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].

INTENT:

Where required life safety systems are incorporated in environmental separators, to limit the probability that the thermal performance of the installed material will fall significantly below expectations, which could lead to the inadequate control of heat transfer through environmental separators under expected environmental loads.
This is to limit the probability of compromised operation of temperature-sensitive or moisture-sensitive life safety systems, which could lead to harm to persons.
