Intent 1:
To limit the probability of:
- inadequate fastening of or damage to the interior finish,
- inadequate protection of the insulation, air barrier
system or vapour barrier, which could lead to condensation, which
could lead to deterioration of the assembly, or
- where the interior finish contributes to the required
bracing, inadequate performance of the interior finish, which could
lead to an inability to resist expected lateral loads, which could
lead to excessive racking.
This is to limit the probability of
compromised fire resistance of the wall, which could lead to insufficient
fire resistance, which could lead to the spread of fire from the building
to an adjacent building during the time required for emergency responders
to perform their duties.
This is to limit the probability of damage to the adjacent
building.
