Our durable solar pool covers can increase the temperature of your pool by up to 17 degrees! Our solar pool covers are made to give you maximum pool heating properties combined with a long durable life. Our Solar Blankets are made from a film of thousands of tiny bubbles, which work together to collect and retain heat in your pool at night and on those chilly days. The Solar Blanket floats on top of the water and allows the solar energy to pass through, then traps it as retained heat in the pool. It is also ideal as a thermal blanket for heated pools.
