# Armor Ball AQUA: spherical floating cover

> Armor Ball AQUA is AWTT's 100 mm self-filling, water-ballasted HDPE sphere for modular surface coverage, published by AWTT at 91% coverage and up to 90% evaporation reduction.

Armor Ball AQUA is a named AWTT product, not a generic label for every shade ball. Its published specification gives designers a defined spherical option to compare with hexagonal tiles and continuous covers.

## What is Armor Ball AQUA?

Armor Ball AQUA is a 100 mm UV-stabilised HDPE floating sphere made by AWTT. The element fills with water on deployment, increasing its published mass from 50 g dry to 275 g when ballasted. AWTT specifies 108 balls per square metre, producing 91% surface coverage.

The product is designed as a modular surface layer. It does not create a sealed gas-capture membrane, and its spherical geometry does not eliminate every opening between elements.

## How Armor Ball AQUA works

- **Self-filling ballast.** Water enters the sphere's ballast chamber after deployment.
- **Close-packed field.** Individual balls distribute across the surface at the AWTT-published placement density.
- **Anchorless placement.** AWTT describes tool-free installation by pouring the elements onto the liquid surface.
- **Independent movement.** Each sphere follows changing water level without a continuous perimeter sheet.
- **Documented envelope.** AWTT publishes the product's dimensions, coverage, wind resistance, material, operating temperature, lifecycle, and warranty.

## Benefits of Armor Ball AQUA

| Published property | AWTT value | Design meaning |
|---|---|---|
| Surface coverage | 91% | Modular shading with geometric gaps |
| Evaporation reduction | Up to 90% | Manufacturer-published maximum, not a site guarantee |
| Wind resistance | 75 MPH (120 km/h), AWTT-published | Use within the confirmed project design |
| Material | UV-stabilised HDPE | Verify water-contact documentation for the use |
| Life expectancy | 25+ years | Manufacturer-published design figure |
| Warranty | 10 years | Confirm terms with the supplied quotation |

AWTT also publishes an operating range of −57 °C to +71 °C and states that potable-water or food-contact HDPE can be specified, with supporting documentation available on request. Project approvals remain tied to the exact supplied formulation and jurisdiction.

## When to use Armor Ball AQUA

Evaluate Armor Ball AQUA when a pond or tank benefits from a free-moving spherical layer, particularly where an irregular perimeter or internal obstacles make a tiled field less convenient. The geometry can also suit projects where easy pour-on placement is important.

The correct choice still depends on surface area, wind, overflow protection, water chemistry, access, and the required surface-management outcome. EuroCover confirms product quantity, commercial availability, and delivery details at quotation.

## Armor Ball AQUA vs hexagonal cover

Armor Ball AQUA uses 100 mm spheres and provides AWTT-published 91% surface coverage. Hexprotect® AQUA uses tessellating hexagonal elements and has a different published coverage and wind envelope. Neither topology is universally superior: spheres accommodate irregular edges; hexagons create a denser modular field.

Use the [hexagonal vs Armor Ball AQUA comparison](/vs/hexagonal-vs-armor-ball) for the full choice, then request a project review rather than applying a generic area threshold as a guarantee.

## Frequently asked questions

### What size is Armor Ball AQUA?

AWTT publishes a 100 mm (4 in) ball diameter for Armor Ball AQUA. The published density is 108 balls per square metre (10 per square foot).

### How does Armor Ball AQUA ballast itself?

Each sphere has a self-filling water chamber. AWTT publishes a dry mass of 50 g and a water-ballasted mass of 275 g for the documented product.

### What surface coverage does it provide?

AWTT publishes 91% surface coverage. The remaining area is associated with the gaps created when circular elements pack together.

### What performance does AWTT publish?

The manufacturer page lists 75 MPH (120 km/h) wind resistance, up to 90% evaporation reduction, UV-stabilised HDPE, a −57 °C to +71 °C operating range, 25+ year life expectancy, and a 10-year manufacturer warranty.

### Is Armor Ball AQUA available in Europe?

EuroCover has an EU product page for Armor Ball AQUA. Exact availability, quantities, origin, and lead time are confirmed at project quotation; this page does not claim stock or a fixed delivery window.
