Sentence 9.23.3.1.(2)

Intent 1:

To limit the probability that nails of insufficient diameter will be used, which could lead to inadequate withdrawal resistance, pull-through resistance or shear strength, which could lead to an inability to resist expected vertical or lateral loads, which could lead to fastened elements detaching from supporting members.

Where wood-frame construction supports or is part of an environmental separator, this is to limit the probability of the displacement or failure of required environmental separation elements, which could lead to:

• condensation,
• precipitation ingress,
• excessive heat transfer,
• pollutant ingress, or
• compromised thermal performance of components intended to resist heat transfer.

This is to limit the probability of:

• inadequate control of temperatures of interior spaces, drafts, relative humidity or water accumulation,
• the generation of pollutants from biological growth or from materials that become unstable on wetting, or
• deterioration, which could lead to further compromised integrity of environmental separators.

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.
