The GeoBubbleTM standard product range is comprised of a variety of traditional colour options incorporating the innovation of our patented GeoBubbleTM technology offering 25% longer lifespans then the traditional packaging bubble design. We divide these products into 2 categories based on their characteristics and how they work on your pool. Firstly, our transmission covers (Light Blue, Dark Blue, French Blue) are designed such that they transmit a large proportion of the visible and IR radiation from the Sun, utilising it to heat the water and basin of your pool. Our own testing has shown that our Light Blue material is capable of increasing the temperature of your pool by up to 3°C in the UK. Our other class of standard product are opaque covers. Opaque covers do not heat your pool via transmission of solar energy, instead they transfer energy by absorption and heat the water’s surface. Opaque covers do not heat a pool as efficiently as transmission covers; however, they are advantageous that they are highly efficient at inhibiting algae growth.
