Thermal Foam

Designed to float on the water’s surface, the THERMAL-FOAM floating spa blanket is lightweight and durable. It protects and extends the life of your spa insulating cover while significantly reducing heat loss and chemical evaporation/consumption. Blue in color and made of 1/8” thick closed-cell polyethylene foam, these blankets are easily cut to size, and much more resistant to “bunching up” than the bubble blankets.
