9.29.8.2.(2)


Objective	OH1 Indoor Conditions
Attribution	[F20,F22-OH1.1,OH1.2] Applies where interior finishes support or serve as required environmental separation elements.
Application	Application 1: Minimum thickness and maximum support spacing of insulating fibreboard tile interior wall and ceiling finishes, in buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9].
	Top of Page
Intent	Intent 1: To limit the probability of inadequate rigidity, which could lead to an inability to resist expected impact, gravity or lateral loads. Where interior finishes support or serve as required environmental separation elements, this is to limit the probability of the deformation or detachment of interior finishes, which could lead to the failure of required environmental separation elements, which could lead to: condensation, precipitation ingress, pollutant ingress, or compromised thermal performance of components intended to resist heat transfer. This is to limit the probability of: an inadequate control of temperatures of interior spaces, 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, or the inadequate thermal comfort of persons. This is to limit the probability of harm to persons.
