Back5.3.1.2.(2)

ATTRIBUTION:

Functional Statement:

F63

To limit moisture condensation.

Objective:

OH1.1

 

APPLICATION:

Metal-framed glazed assemblies separating interior conditioned space from interior unconditioned space or exterior space that are installed to provide resistance to heat transfer 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 of the inadequate control of heat transfer through metal-framed glazing assemblies under expected environmental loads, which could lead to condensation.
This is to limit the probability of:
  • the generation of pollutants from biological growth or from materials that become unstable on wetting, or
  • deterioration, which could lead to compromised integrity of the separators.
This is to limit the probability of negative effects on the air quality of indoor spaces, which could lead to harm to persons.

INTENT:

To limit the probability of the inadequate control of heat transfer through metal-framed glazing assemblies 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.
