Intent 1:
To limit the probability that the performance of
horizontal and vertical strip aluminum siding will fall significantly
below expectations, which could lead to:
- premature failure, or
- an inability to effectively shed water.
This is to limit the probability of:
- precipitation or meltwater ingress, or
- compromised thermal performance of components intended
to provide resistance to heat transfer.
This is to limit the probability of:
- an inadequate control of temperatures of interior spaces
or relative humidity,
- the generation of pollutants from biological growth
or from materials that become unstable on wetting,
- deterioration, which could lead to compromised integrity
of exterior walls or elements protected by exterior walls, or
- the accumulation of water in interior spaces.
This is to limit the probability of:
- negative effects on the air quality of indoor spaces,
- the inadequate thermal comfort of persons, or
- contact with moisture.
This is to limit the probability of harm to persons.
