Constructed with thousands of downward-facing air-filled bubbles and an 8-mil durable film, the blanket transfers solar energy into the water while slowing heat loss and evaporation. It’s sized for 21-foot round above-ground pools, is easy to trim with scissors around ladders or returns, and stores compactly when rolled and kept dry.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this cover warm my pool without extra equipment?\u003c\/h3\u003e\n\u003cp\u003eThe cover’s bubble structure traps solar radiation and positions it close to the water surface so heat moves into the pool naturally.
