- EXTENDS THE SEASON - This 16-mil solar blanket uses passive solar heating to increase the temperature of your hot tub up to 15 degrees Fahrenheit. Hot tub cover has better heat preservation and water retention effect, the bubbles will not crack or fall off, and the round solar cover can be used for a long time.
- Trim to Fit: Our thermal solar blanket cover is 7*7ft and fits most inflatable round style hot tubs. If your tub has more irregular shapes, you can put the cover over the hot tube first, then make a mark and cut along the mark.
- SAVE ENERGY - The insulating thermal bubbles trap heat while the transparent blue color lets in maximum solar rays, making this cover energy-efficient all summer long. Spa Solar Cover is designed to withstand exposure to chemicals and UV radiation and will tolerate even the most intense sunlight.
- REDUCE EVAPORATION: Prevent up to 95% of water and chemical evaporation with the use of a solar blanket. This reduction of evaporation is not only environmentally friendly, it will save you time and money, as well. Suitable for spa, pool and hot tub.
- Bubble-side Down: When using, you need to put the bubble side of the solar blanket for hot tubs close to the water surface, with the smooth side facing up, which can also play a role in preventing dust, reducing condensation and freezing on the edge.
