New for 2025, Energy Guard Selective Transmission has been awarded the 2018 Business Innovation Award for delivering significant societal and economic impact through the application of physics.

Selective Transmission

The 500 micron bubble layer of the material uses a patented midnight blue pigment combination which gives the material its selective transmission properties.  The pigment formulation works as a selective filter absorbing the visible wavelengths responsible for photosynthesis.  This absorbed energy is passed to the pool though conduction, while the transmission properties of the bubble layer allows for Infrared Radiation wavelengths to pass through the material and be directly absorbed by the water.  

Debris and Algae Control

As well as preventing debris from entering the pool, Energy Guard Selective Transmission helps maintain a pleasant, warm swimming environment by using light filtration technology to absorb wavelengths that promote the growth of algae, reducing the cost and time spent on maintenance.

Heat Retention

The unique profile of the GeoBubble technology air cells provide both buoyancy and an insulative air gap to control heat transfer enabling the material to manage the pool environment and keep the pool the desired temperature.

Evaporation Control

Our materials reduce water losses through evaporation by working as a barrier between the water's surface and the atmosphere.  By simply covering the pool with the material, evaporation is reduced by over 98% resulting in the preservation of the water resources and increased temperature within the swimming pool
