Louvre roof
Useful where adjustable shade, ventilation and a closable roof plane are central to how the outdoor room is used.
- Adjustable blade angle
- Integrated drainage pathway
- Residential + hospitality use
New Zealand New Zealand / Decision guide
The three pathways can all create useful outdoor shelter, but they solve different problems. Start with how much movement, weather control, opening area, drainage, maintenance and architectural integration the project needs.

Direct answer
Start with CADARN when adjustable louvre control is the main requirement; FASGAR when fixed or retractable non-louvred overhead cover is stronger; and AUVENOR where a more specialised moving architectural system better matches the project. Final wind, structure, drainage, consent and installation requirements remain project-specific.
Project decision
These comparisons are designed to narrow the project route. They do not replace local engineering, authority review or exact-system technical evidence.
Useful where adjustable shade, ventilation and a closable roof plane are central to how the outdoor room is used.
Useful where opening a significant portion of the roof is part of the experience and the project can accommodate moving components, controls and maintenance access.
Useful where dependable permanent overhead cover and simpler operation matter more than changing the roof opening.
Comparison matrix
Site wind, exposure, drainage, structural support and local approvals still need project-specific review.
| Factor | Louvre | Retractable | Fixed |
|---|---|---|---|
| Primary benefit | Adjustable sun + ventilation | Open-sky flexibility | Permanent cover |
| Movement | Blade rotation | Roof retracts / moves | None |
| Weather strategy | Closable roof plane | Variable open / closed | Continuous cover |
| Maintenance | Motor + drainage | Mechanism + controls | Generally simpler |
| Typical project | Outdoor room / terrace | Hospitality / premium outdoor | Shelter-led space |
Project brief
Frequently asked
No. The decision page is a shortlisting tool. Final suitability depends on the actual site, use, dimensions, exposure, selected system, available evidence and local project requirements.
Apollo is supply-led. Local engineering, approvals, foundations, services, installation and other site works remain with the appointed local project team unless a written project scope expressly includes something different.
No. Apollo uses a manual project-brief process so the selected system, quantities, destination, freight and project interfaces are reviewed before pricing.
Next step
Send the site, dimensions, use, quantities, exposure information and known local requirements. Apollo can then review the relevant systems, evidence, freight and supply scope.
