Deluxe 15 ft. x 30 ft., 3-Year Oval Solar Pool Blanket

The Pool Mate Deluxe 3-year blue solar blanket is made of heavy-duty polyethylene material that works with the sun to catch and retain heat. Solar blankets float bubble side down on the surface of your pool water when the pool is not in use . allowing solar energy to pass through and trapping it as retained heat in the pool. Helps raise the water temperature by absorbing sunlight during the day and retaining the heat at night . extending the pool season. Savings come from a reduction in water evaporation decreasing chemical consumption. Material is highly resistant to ultra-violet rays which inhibits deterioration.
