9.20.13.9.(2)


Objective	OH1 Indoor Conditions
Attribution	[F61,F62-OH1.1,OH1.2,OH1.3]
Application	Application 1: Flashing for exterior masonry walls where water will accumulate and the interior finish is of a type that may be damaged by moisture, in buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9]: where the wall height above the foundation wall does not exceed 11 m, and in which the roof or floor system above the first storey is not of concrete construction. Exceptions: except as stated in: Sentence 9.20.13.9.(3), which applies to walls where the finish is protected by insulation that effectively limits the passage of water and is applied by a waterproof adhesive or mortar directly to parged masonry, and Sentence 9.20.1.1.(2), which applies to buildings other than described above, or where the masonry is designed for specified loads on the basis of ultimate and serviceability limit states.

Intent	Intent 1: To limit the probability of inadequate drainage, which could lead to water penetrating the interior surface of solid masonry walls, flowing along the interface of the sheathing membrane material and the interior surface of the masonry, and collecting in the wall. This is to limit the probability of: precipitation or meltwater ingress, or compromised thermal performance of components intended to resist heat transfer. This is to limit the probability of: 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.
