Fixed cover
Permanent clear-span roofs or halls provide a stable overhead condition for sport, lighting and venue operation. Envelope, ventilation and heat control still need to suit the climate and sport.
International Decision Centre / Global
The decision is not only whether the roof moves. A sports cover has to protect the playing volume, preserve clearances, respond to local wind and rain, coordinate lighting and services, and remain practical to operate and maintain.

Direct answer
Choose a fixed cover when dependable year-round shelter, stable clearances and simpler venue operation are the priority. Consider a retractable cover when opening the venue to the sky is valuable enough to justify the additional mechanism, operating rules, maintenance access and project-specific engineering.
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.
Permanent clear-span roofs or halls provide a stable overhead condition for sport, lighting and venue operation. Envelope, ventilation and heat control still need to suit the climate and sport.
A retractable system can create an open-air venue condition, but rails, drives, stacking zones, controls, wind limits and maintenance become part of everyday facility planning.
Run-off, side height, apex height, ball trajectory, lighting, netting, scoreboards and spectator areas should be resolved before the cover geometry is frozen.
Comparison matrix
Exact suitability depends on the sport, site and verified system capability.
| Factor | Fixed cover | Retractable cover |
|---|---|---|
| Weather protection | Consistent overhead cover | Variable / operable |
| Venue operation | Simpler | Requires opening / closing procedure |
| Mechanical complexity | Lower | Higher |
| Open-air experience | Limited | High when open |
| Maintenance | Structure + envelope | Structure + envelope + moving system |
| Wind strategy | Engineered permanent condition | Engineering plus operating limits |
| Best fit | Year-round covered sport | Flexible venues where open sky has real value |
Project brief
Frequently asked
No. The useful choice depends on the project outcome, site conditions, scale, local work, operating expectations, maintenance and the technical evidence available for the exact system.
No. Apollo uses a project-brief and quotation process so product family, configuration, quantity, destination, freight and project interfaces are reviewed before pricing.
Apollo is primarily supply-only. Local engineering, approvals, foundations, services, installation and other site work remain with the appointed local project team unless a written scope states otherwise.
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.
