Choose 5 MIL to 16 MIL for HEAT RETENTION and LONGEVITY

Solar Pool Covers
These 21 ft. round solar blankets help you to extend your swimming season and cut energy costs by reducing your reliance on gas pool heaters. Solar covers gradually raise the pool water temperature by absorbing sunlight during the day and retaining the extra heat at night. Our 21 ft. round pool solar covers are available in 5 mil, 8 mil, 12 mil and 16 mil thicknesses. The 5 mil blanket is the most affordable option; choose our thicker 8 or 12 mil blankets for even greater heat retention and longevity. Our thickest 16 mil Ultra Clear solar cover combines an aluminized bottom layer and clear top layer that together maximize the sun’s warming rays by reflecting the absorbed heat back into the pool.
