Sun rays pass through the solar cover and heat the water directly below the surface. When exposed to sunlight, the bubbles act like lenses, which can make water heating more effective.
At night, the solar cover helps prevent evaporation of both water and pool chemicals and reduces heat loss. At the same time, it provides basic protection against debris falling into the pool. The cover is made of a blue bubble polyethylene thermal-insulation film.
