Intent
Intent 1: 
To limit the probability that the performance of exterior wood doors will fall significantly below expectations, which could lead to:
  • infestation by insects or vermin,
  • precipitation ingress,
  • excessive heat transfer, or
  • excessive air infiltration or exfiltration.
This is to limit the probability of:
  • the ingress of airborne pollutants,
  • the inadequate control of temperatures in interior spaces, or drafts,
  • the generation of pollutants from biological growth or from materials that become unstable on wetting, or
  • deterioration, which could lead to compromised integrity of elements protected by doors.
This is to limit the probability of:
  • negative effects on the air quality of indoor spaces, and
  • the inadequate thermal comfort of persons.
This is to limit the probability of harm to persons.
