Intent 1:

To limit the probability of water running down the face of the sheathing membrane or insulating sheathing, which could lead to water entering the backing assembly.

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.
