Intent 1:
To limit the probability of:
- inadequate thermal resistance, which could lead to excessively
low temperatures of interior surfaces or within assemblies, which
could lead to condensation, or
- the transfer of absorbed moisture into the masonry,
which could lead to deterioration due to freeze-thaw stresses.
This is to limit the probability of
compromised structural integrity of assemblies acting as environmental
separators, which could lead to harm to persons.
Intent 2:
To modify the application of Sentence 9.25.2.4.(1) to include masonry cavity walls.
