The EnergyGuard™  is New Zealand's first and only award-winning dual-purpose pool cover created to maximise pool temperature and inhibit algae growth.





Increasing pool temperatures and inhibiting algae growth are now possible with our innovative selective light filtering material. 

What is an EnergyGuard™ Selective Transmission cover?

EnergyGuard™ ST pool cover material absorbs the wavelengths that promote algae growth. This absorption heats the cover and thus the pool via conduction. The material also allows the transmission of longer wavelengths directly into the water, heating the pool. Ultimately, the light normally used by algae for growth is instead used to heat the pool, and the algae dies off. The pool is also heated by the longer wavelengths which are free to pass through the cover and into the water. Through this selective transmission process algae growth is inhibited and solar heat gain is promoted.

How does this translate into financial savings?

An EnergyGuard™ Selective Transmission cover saves money by reducing water, heating, electricity and chemical consumption. The cover has a payback period of approximately one year or less.
