Intent

Intent 1:

To limit the probability that the wind uplift resistance of membrane roofing systems will be incorrectly determined, which could lead to

  • structural damage of membrane-roofing systems, and
  • excessive air leakage, which could lead to excessive heat transfer, condensation or precipitation ingress.

This is to limit the probability of

  • the inadequate control of temperatures of interior spaces, relative humidity, drafts, or water accumulation,
  • the generation of pollutants from biological growth or from materials that become unstable on wetting, or
  • deterioration, which could lead to compromised membrane-roofing assemblies.

This is to limit the probability of:

  • negative effects on the air quality of indoor spaces,
  • the inadequate thermal comfort of persons, and
  • contact with moisture.

This is to limit the probability of harm to persons.
