The Problem With Comparing Only Unit Price
A floating cover quote is often evaluated as a simple cost-per-area number. That shortcut can be misleading because a lower initial cost may also mean lower surface coverage, lower wind resistance, or a narrower application range. For industrial ponds, the better question is not "Which cover is cheapest?" It is "Which cover delivers the required performance at the lowest practical total cost?"
Armor Ball is AWTT's cost-effective ball-cover family. Hexprotect is AWTT's interlocking hexagonal tile family. Both are modular, both use HDPE construction, and both can reduce evaporation and sunlight exposure. Their cost difference comes from geometry, coverage percentage, wind mechanism, and application requirements.
Where Each Product Family Is Usually the Better Value
| Decision Factor | Armor Ball Advantage | Hexprotect Advantage |
|---|---|---|
| Initial capital budget | Lowest-cost AWTT modular cover option for standard applications | Higher initial cost, justified by stronger coverage and wind performance |
| Surface coverage | 91% coverage from ball packing geometry | Up to 99% coverage from interlocking hexagonal tiles |
| Wind exposure | Armor Ball AQUA provides water-ballasted resistance to 75 MPH | Hexprotect AQUA provides self-loading resistance to 130+ MPH |
| Algae and UV control | Good for budget-sensitive sunlight reduction | Better when near-complete UV blockage is required |
| Site risk | Strong fit for sheltered or moderate-duty ponds | Strong fit for exposed reservoirs, drinking water, and severe-duty industrial sites |
Cost Drivers Behind the Difference
1. Geometry controls exposed water
Spheres cannot tile a flat surface without gaps, so ball covers are limited by packing geometry. Hexagonal tiles interlock with less exposed water between units. That extra coverage can matter when the economic driver is algae elimination, odor suppression, evaporation reduction, or wildlife exclusion.
2. Wind rating changes lifecycle risk
A lower-cost cover can become expensive if wind pushes it into piles, exposes the water surface, or requires repeated site visits. Armor Ball AQUA improves ball-cover wind performance with water ballast. Hexprotect AQUA goes further with interlocking geometry and self-loading ballast chambers for severe exposure.
3. Installation cost is not the full operating cost
Both product families are modular and comparatively fast to deploy. The long-term cost difference is usually driven by the value of water saved, chemical use avoided, maintenance avoided, and compliance risk reduced. For evaporation-heavy applications, use the floating cover ROI guide to compare project economics.
How to Choose by Budget Scenario
Budget is the primary constraint
Start with Armor Ball for sheltered applications or Armor Ball AQUA for moderate wind exposure. This is the usual path when the goal is economical coverage and the site does not require maximum coverage percentage.
Performance risk is the primary constraint
Start with Hexprotect AQUA when the pond is exposed to severe wind, when uncovered water would create operational or compliance risk, or when the project needs up to 99% surface coverage.
The site sits between the two
Compare Armor Ball AQUA against Hexprotect AQUA using the same site assumptions: pond area, wind exposure, target coverage, water value, chemical savings, and expected operating life. AWTT can model both options instead of forcing a one-size-fits-all recommendation.
Why AWTT Quotes Both Instead of One
AWTT manufactures ball, hexagonal, hybrid, and insulated modular covers. That lets the engineering team recommend a lower-cost ball solution when the application is simple, and a higher-performance hexagonal system when the operating risk justifies it. The right answer is the cover that meets the specification without unnecessary cost.

Cost Comparison Checklist
- Define required coverage percentage before comparing product families.
- Confirm sustained wind exposure and fetch distance.
- Assign value to water saved, chemical reduction, and avoided maintenance visits.
- Identify whether regulatory or wildlife risk makes exposed water unacceptable.
- Compare total project value, not just initial unit cost.
FAQs
Is Armor Ball cheaper than Hexprotect?
Armor Ball is typically the lower initial-cost AWTT modular cover. Hexprotect costs more because it delivers interlocking geometry, higher coverage, and stronger severe-wind performance.
When is Hexprotect worth the added cost?
Hexprotect is worth evaluating when the site needs up to 99% coverage, severe-wind resistance, stronger algae control, or tighter protection from exposed water.
Can the two product families be used on the same site?
Yes, if the pond has distinct zones. For example, a wind-exposed section may use Hexprotect AQUA while a sheltered cove uses Armor Ball. The products do not interlock across families, but they can be specified by zone.
