Ideal for reducing thermal losses from open tanks of water. A blanket of hollow spheres covers 91% of the liquid surface, trapping air in the gaps which adds to the thermal insulation properties and reduces steaming with no impedance to workload.
- 5, 8, 10 & 14L baths require two packs of spheres
- 9, 22 & 28L baths require four packs
- 56L baths require eight packs
