Why is the Suncap® material light coloured?
Suncap® Solar pool material is available in blue, green and silver/blue colours. Whilst the blankets have been coloured they are translucent which means that if you placed your hand on the underside of the material you can see the outline of your hand through the material. Solar radiation is the key to heating a pool naturally. When the sun beats down on the pool a translucent cover like the Suncap solar cover allows solar radiation to enter the water, thus heating the pool, as though the cover was absent. In other words, the less transparent the cover, the less radiation entering the water. Dark covers need to absorb the solar energy and then transmit it to the water, allowing a lot less direct penetration of solar energy. The best analogy would be tinting a car window. It is darkened to STOP transmission of heat. It is the same principle for swimming pools.
