Solar Blanket vs. Safety Cover: What Is the Difference?

The name “pool cover” can refer to products with very different purposes. A solar or thermal blanket is designed to help retain heat and reduce evaporation. It is not a safety barrier and cannot keep a child or pet from entering the water.

A safety cover is designed and installed to help restrict access to the pool when properly fitted, secured, and maintained according to the manufacturer’s instructions. The exact requirements depend on the cover type and pool setup.

A cover is one layer of protection. Keep barriers secured, supervise children closely, designate a water watcher, and keep rescue equipment and emergency information ready. Never treat a cover as a replacement for active supervision.

Before buying or using a cover, identify its intended use, confirm compatibility with your pool, and read the manufacturer’s instructions. For safety guidance, see the CDC’s drowning prevention information and the CPSC’s Pools and Spas safety guide.
