Begin with the project documentation
Ask the project designer, bushfire consultant or relevant approval professional to confirm the assessed level and the requirements for each opening. Site conditions, vegetation and building design all influence that work.
A neighbouring property’s specification or a product described only as ‘bushfire rated’ is not enough to establish what your project needs.
Treat the opening as a complete system
Relevant evidence may depend on a particular frame, glazing, seals, screens, hardware, size and configuration. Changing one component can change whether the documented performance still applies.
- Match product identifiers and configurations to the project schedule.
- Check the maximum sizes and opening styles covered by the evidence.
- Confirm screen, seal, hardware and glass requirements.
- Keep approvals and product documents with the project records.
Installation is part of the outcome
The opening, fixings, clearances, perimeter treatment and adjacent wall construction should follow the approved details. Coordinate those interfaces before fabrication wherever possible.
Requirements and standards can change. Always rely on current project documentation and qualified advice rather than a general article—including this one—for a final specification.
A final note
This guide is general information, not project-specific technical or regulatory advice. Confirm your requirements with the appropriate qualified professional.
