5.10.2.4.(2)

Intent 1:

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 2:

To limit the probability of the inadequate control of heat transfer through metal-framed glazing assemblies under expected environmental loads, which could lead to excessive heat loss or gain, which could lead to the inadequate control of temperatures of interior spaces, which could lead to inadequate thermal comfort of persons, which could lead to harm to persons.
