This pool solar film floats on the water surface within the pool edge and can thus warm up the pool water by 5°C depending on sunlight. Thanks to the PE air cushions, the solar film can store warmth longer so that you can extend your bathing season. A cost-efficient way to heat your swimming pool. Additionally, the evaporation of water is reduced and therefore also the use of chemicals. The film is lightweight, easy to install and handle. Size: 600cm W x 400cm D
