These changes include the expansion of the sloped overhead glazing requirements for three-sided support, new test methods to glass barriers (under the new Appendix's) and imposed load table.
Other changes include more stringent requirements for all sloped overhead glazing to be Grade A laminated safety glass, subject to the two exceptions under Section 6.3 for toughened glazing and insulating glass units (IGU).
Relevant building professionals are also reminded of the changes for glass structural barriers equal to or over 1,000mm (1m) in height.
New and amended provisions in relation to the construction of those barriers includes further elaborated requirements for:
- the glass structural barriers with interlinking handrails under Section 7.4.5 (previously Section 7.3.5, AS 1288-2006).
- the glass structural barriers with no handrail or non-load supporting handrail with detailed requirements for spigot-fixed, point-fixed and core drilled barriers and use of fixing channels under Section 7.4.6
While the preface from the Australian Standards can be a useful tool for a quick insight into the updated changes, industry is reminded to carefully read through each of the provisions of the newly adopted Australian Standards that are subject to be applied for the construction of new building work under the NCC 2022.
All building practitioners are reminded to take care in making sure that when applying the current version of the NCC 2022, that all new or updated provisions from these newly adopted standards have been researched and correctly applied.
