These roof pathways solve different problems. Start with how much movement, weather control, opening area, structural integration and maintenance the project can support.
Direct answer
Choose a louvre roof when adjustable sun and ventilation are central; a retractable roof when opening the roof area is a major part of the experience; and a fixed roof when permanent cover and simpler operation matter more than movement.
Project decision
Use these points to structure the first project conversation. Final suitability stays tied to the actual site, selected system and local project team.
Rotating blades stay within the roof plane and adjust light, ventilation and rain protection. They suit outdoor rooms where changing weather conditions matter but the structure should remain visually consistent.
Retractable systems create a stronger open-sky effect by moving the roof away rather than only changing blade angle. CADARN APERTA is Apollo's standard-size-first aluminium pathway: standalone, wall-mounted or roof-only, with made-to-measure sizing available and an approximately 30% stacked roof depth when fully retracted.
Fixed roofs are strongest where permanent shelter, simpler operating logic and a stable overhead condition are more important than opening the roof. Drainage, structure and local approvals still remain project-specific.
Comparison matrix
Use this as a project-screening matrix, not a substitute for engineering or a final specification.
| Factor | Louvre roof | Retractable roof | Fixed roof |
|---|---|---|---|
| Primary benefit | Adjustable sun / ventilation | Large open-roof effect | Permanent cover |
| Movement | Rotating blades | Roof physically retracts / stacks | None |
| Maintenance complexity | Moderate | Higher | Lower |
| Weather strategy | Adjust + close | Open / retract / close | Always covered |
| Typical fit | Outdoor rooms, hospitality | Premium hospitality, flexible spaces | Permanent shelter, circulation |
Project brief
Frequently asked
No. Site conditions, scale, permanence, local works, operating expectations and documentation requirements change the right starting point.
No. Apollo uses a manual project-brief process so the selected system, quantities, destination, freight and project interfaces are checked before pricing.
Apollo supplies products only. The purchaser independently arranges and manages all engineering, approvals, foundations, services, installation, contractors and site works. Apollo does not organise onsite providers.
Next step
Send the site, dimensions, intended use, quantities and known local requirements. Apollo will review the relevant product pathway and keep local engineering, approvals and site-work responsibilities explicit.
