This pool solar foil lies directly on the water surface inside the pool edges and can therefore increase the temperature of your pool water by up to 1 °C depending on the hours of sunshine. Equipped with PE air cushions, the solar tarpaulin can store heat for much longer. This is the most cost-effective way of keeping your pool water warm and heated. What's more, it reduces water evaporation and minimises the use of chemicals. The tarpaulin is suitable for smaller pools and is very easy to install and handle thanks to its low weight.
