Intent 1:
To limit the probability of:
- precipitation or meltwater ingress, or
- compromised thermal performance of components intended
to resist heat transfer.
This is to limit the probability of:
- the deterioration of masonry due to freeze-thaw stresses,
which could lead to masonry falling, or
- the deterioration of elements inboard of the masonry,
which could lead to compromised structural integrity, which could
lead to structural collapse.
This is to limit the probability of harm to persons.
