Ball Cover vs. Floating Membrane Cover
| Attribute | Floating membrane cover | Armor Ball® ball cover |
|---|---|---|
| Installation | Engineered, fabricated, anchored | Poured onto the surface, tool-free |
| Anchoring / liner penetration | Required | None |
| Adapts to level changes | Limited; needs slack management | Self-adjusting |
| Equipment access | Cover must be moved/opened | Balls push aside, then re-cover |
| Rain / snow | Sheds; needs drainage management | Passes through |
| Pond geometry | Custom-fit per site | Works in any geometry |
| Gas-tight containment | Yes (sealed) | No (suppresses, not seals) |
| Maintenance | Periodic inspection / repair | None |
How to choose: Choose a sealed membrane when you need gas-tight containment or biogas capture. Choose a ball cover for evaporation, UV/algae, odor suppression, and insulation with minimal install and maintenance.
