9.6.7.2.(1)ATTRIBUTION:
Functional Statement:
F63
To limit moisture condensation.
Objective:
OH1.1, OH1.2
APPLICATION:
Thermal breaks for metal frames for doors, for glazing
in doors, and for sidelights for doors, 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 resistance to thermal
conduction, which could lead to excessive cooling of the interior surfaces
of metal frames and adjacent air, 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 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.
