Intent 1:
To limit the probability that the windows, doors
and skylights will have inadequate resistance to loads imposed upon
them by structural forces, air pressure or water penetration, or that
they have insufficient protection against the ingress of insects and
vermin, which could lead to:
- precipitation into interior space,
- leakage of air induced by air pressure difference due
to wind loads, water and snow ingress,
- damage or structural failure due to snow loads on skylights
or where windows have sloped or near-horizontal components, or
- infestation by insects and vermin.
This is to limit the probability of:
- damage or structural failure, or
- deterioration and resultant damage to environmental
separators.
This is to limit the probability of harm to persons.
