Back9.25.2.3.(8)

ATTRIBUTION:

Functional Statement:

F21

To limit or accommodate dimensional change.

Objective:

OH1.1, OH1.2

 

APPLICATION:

Installation of insulation in walls, ceilings, roofs or floors separating heated space from unheated space, in factory-built buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9].

INTENT:

To limit the probability of inadequate thermal resistance, which could lead to excessively low temperatures of interior surfaces or within assemblies.
This is to limit the probability of condensation, which could lead to:
  • an inadequate control of the temperature of interior spaces or relative humidity,
  • the generation of pollutants from biological growth or from materials that become unstable on wetting, or
  • deterioration, which could lead to compromised integrity of assemblies acting as or protected by 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 of inadequate thermal resistance, which could lead to excessively low temperatures of interior surfaces or within assemblies.
This is to limit the probability of condensation, which could lead to deterioration, which could lead to compromised structural integrity of assemblies acting as or protected by environmental separators, which could lead to harm to persons.
