Use our rectangular solar blanket for both in-ground and above-ground pools to effectively reduce water evaporation. Featuring an opaque blue design, this blanket maximizes sunlight absorption for optimal heat retention. Even after the sun goes down, the insulating bubbles lock in the heat, keeping your pool warm even on cloudy days and cool nights. This innovative technology can raise your pool water temperature by up to 8–15°F. Our blanket comes with a 3‑ to 5‑year warranty and is built to last, withstanding years of direct sunlight and harsh weather conditions.
