Intent
Intent 1: 
To limit the probability of water running back under window sills or down the face of masonry, which could lead to water ingress.
This is to limit the probability of compromised thermal performance of components intended to resist heat transfer, which could lead to:
  • an inadequate control of temperatures in interior spaces, relative humidity or water accumulation,
  • the generation of pollutants from biological growth or from materials that become unstable on wetting, or
  • deterioration, which could lead to further compromised integrity of environmental separators.
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.
