Functional Statement:

F63

To limit moisture condensation.

F51

To maintain appropriate air and surface temperatures.

F63

To limit moisture condensation.

Objective:

OH1.1, OH1.2

 

APPLICATION:

Minimum number of glazing layers in doors and adjacent sidelights that separate heated space from unheated space or from the exterior, in 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:
  • the excessive cooling of glass and adjacent air, or
  • the inadequate control of heat transfer through doors.
This is to limit the probability of:
  • the inadequate control of temperatures in interior spaces, or
  • 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 or performance of doors or sidelights, or of building components protected by doors or sidelights.
This is to limit the probability of:
  • negative effects on the air quality of indoor spaces,
  • the inadequate thermal comfort of persons, and
  • contact with moisture.
This is to limit the probability of harm to persons.
