HEAT MAINTENANCE The bubble cover prevents heat loss and maintains the water temperature: a pool not protected by a bubble cover loses between 4 and 5C per night, compared to 1 or 2C maximum for a protected pool. LIMITS EVAPORATION The bubble cover also has two other functions: it considerably reduces water evaporation by up to 90% and protects your pool from external pollution and other impurities (leaves, insects, dust). RESISTANT With a thickness of 180 microns and made of honeycomb PE, a robust and unalterable material, the bubble cover is intended to be anti-UV and anti-cryptogamic treated, i.e. say without mold and without altering its quality. MODULABLE Our bubble covers have neither edges nor eyelets so that you can adjust the cover to your pool with simple scissors. However, you can add eyelets simply and without the risk of tearing or fraying.
