Heavy-duty polyethylene material works with the sun to catch and retain heat. Helps raise the water temperature by absorbing sunlight during the day and retaining the heat at night, extending the pool season. Material is highly resistant to ultraviolet rays which inhibits deterioration. Energy cost savings come from a reduction in water evaporation.

This Solar Cover is made of a tough 12 mil material. This is a one piece cover that will stand up to the harshest sun, and the coldest cold. This solar cover is make of durable resin and has thousands of little air bubbles that will transmit and capture the sun which will generate solar heat to your pool. Being thicker, it will help hold in the heat at night better than the 8 mil for an average temperature raise of about 15 degrees.
