Frogspawn – Thermal Insulation Spheres

Floating Insulation for Open Process Tanks

Frogspawn Thermal Insulation Spheres are a simple yet highly effective solution
for reducing heat loss, vapour emissions, and energy consumption in open-topped industrial tanks. These hollow polymer spheres float on the surface of liquids to form a continuous insulating blanket, ideal for use in electroplating, anodising, chemical processing, and steel treatment.
