All bubble covers are designed to float directly on the water surface. A solar bubble pool cover is made from a translucent material to maximise energy gain from sunlight i.e. the Sol+ Guard 500 Micron Solar Cover. A heat retention or heat absorbing bubble covers like the Gold 500 Micron Solar Cover are generally made from dark opaque coloured material, designed to minimise energy loss and absorb the suns heat. Heat reflective bubble covers are designed for very hot climates to reflect the suns heat away from the pool surface, and are generally made from light opaque coloured material designed to reflect the suns heat.
