Objective | OS2 Structural Safety |
Attribution | |
Application | Application 1: Minimum joint offset for panel-type underlay required
to be installed over plywood, OSB or waferboard, in buildings to
which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application
of Part 9]. |

Intent | Intent 1: To limit the probability that excessive differential movement
of adjoining subfloor panels will be transmitted through the underlay panels,
which could lead to the displacement or cracking of finished flooring.
Where finished flooring is required to provide water resistance,
this is to limit the probability of the ingress of water into the subfloor,
which could lead to compromised structural integrity of the supporting structure,
which could lead to an inability to resist expected gravity loads, which could
lead to structural collapse, which could lead to harm to persons.
