Water that’s always warmer

Once the Coverseal cover is closed, it does not come into contact with the water in your swimming pool and forms a cushion of air that envelops and protects the pool. It acts as a heat shield stretched above the pool, which is cooler (especially at night-time, when the temperature difference is increased). Coverseal therefore helps to retain the energy stored by the swimming pool during the day.

• During the day… Coverseal stops the water cooling down in contact with the breeze.
• During the night… Coverseal stops the surface water cooling down in contact with colder air. The heat from solar energy stored during the day is retained, so you can take a dip in the evening or first thing in the morning.
• At any time of day… Coverseal limits evaporation, providing a simple, environmentally friendly way to maintain the water level in your pool and control the various maintenance parameters and the pH.

The ideal solution for indoor pools

No other flexible cover limits evaporation to the same degree as the Coverseal airtight cover. Specially designed to keep the membrane properly tensioned and sealed, it is the ideal solution for indoor pools.
