Naturefalls 40 x 20 ft Rectangular 16 mil Solar Pool Blanket for In-Ground and Above-Ground Pools Rich Blue

This 40 x 20 ft rectangular solar pool blanket is engineered for both in-ground and above-ground swimming pools, delivering measurable heat retention and water conservation. The 16 mil Polyethylene construction resists tears and tensile stress, while the closed-bubble design blocks up to 95% of evaporation to preserve water and reduce refill frequency. Operating as a passive solar heater, the blanket absorbs daytime warmth and limits nighttime heat loss, supporting water temperature increases of 8-15 degrees Celsius depending on conditions. Its rich blue surface keeps leaves and dust out of the pool, cutting cleaning time and maintenance demands throughout the swimming season.
