Intent 1:
To limit the probability that the installation of
field-assembled, manufactured or pre-assembled windows, doors, and
skylights will fall significantly below expectations.
This is to limit the probability of:
- premature deterioration of materials and components
used for the installation,
- condensation on the surface of building elements and
within assemblies,
- precipitation into interior space, or
- leakage of air induced by air pressure difference due
to wind loads.
This is to limit the probability of:
- structural damage due to snow loads on skylights or
where windows have sloped or near-horizontal components, and
- condensation or water accumulation, which could lead
to deterioration, which could lead to compromised structural integrity
of assemblies acting as environmental separators.
This is to limit the probability of harm to persons.
