Maximising pool temperature and inhibiting algae growth at the same time is now possible with award winning light filtration material, meaning there is no need to compromise between temperature and chemical savings. Offering optimised solar gain, the patented EnergyGuard® Selective Transmission material provides the best possible balance between reduced solar heat gain, chemical use and filtration, making it the most innovative solar cover available today. The bubble layer of the material uses a nocturnal blue pigment that gives the material its selective transmission properties. This functions as a selective filter that absorbs the visible wavelengths responsible for photosynthesis.

This absorbed energy passes into the pool by conduction, while the transmission properties of the bubble layer allow wavelengths of infrared (IR) radiation to pass through the material and be absorbed directly by the water.
