Technical analysis
Detailed installation sequence with Australian and New Zealand compliance references for low-rise light-steel construction.
Engineering scope
- Principle
- Install from the base upward and connect the membrane to opening flashings and drained cavities.
- Verification
- Australian work should review NCC and AS 4200; New Zealand light-steel work should review NZBC E2/AS4 and NASH requirements.
- Field control
- Local approval, wind design and product evaluation remain project-specific.
System decision
Start with the actual roof or wall build-up, climate, indoor condition and risk at the relevant interface. Product data must be connected to a defined layer and detail.
Documentation and acceptance
Keep design details, approved product data, delivery labels, batch records, mock-ups, concealed-work photographs and repairs traceable to the installed area.
