The Thermal GeoBubble Cover is designed to utilise the sun’s rays to gradually warm the entire pool using solar energy only. It floats on the surface of the water, bubble side down, and can be trimmed to fit all pool sizes and shapes. This cover can be accessorised with a Rollup Station to aid use and extend the cover’s lifespan. A popular cover choice for school, gym and other commercial or large swimming pools with lanes.


  • Made from 400 micron polyethylene with UV inhibitors.
  • Can be accessorised with a Rollup Station to aid use on larger pools.
  • Can be accessorised with Wind Protection for pools in areas where winds can exceed 35km/hr. In winds over 65km/hr, the cover should be removed from the pool.


Comes in blue.


The Thermal GeoBubble Cover has a one year warranty but will last up to six years with correct care.

Added Benefits

The water temperature is raised by 6 to 8° C which extends the swimming season either side of summer. Temperate water makes for a more enjoyable summer/peak swimming season too.

For heated pools, a thermal cover is the most effective way to prevent heat loss into the atmosphere. It also protects against overnight drops in temperature, and solar panels and heat pumps are notably more effective where the cover is in use.

Because the cover is in direct contact with the water, it can’t evaporate, translating into significant water savings.

Prevents dirt and debris collecting in the pool,  so the water is kept cleaner and pool maintenance is reduced.

Reduces the carbon footprint of the swimming pool by using less energy to heat and clean the pool. The cover is water-wise too, given the reduction in evaporation. Chlorine naturally dissipates in sunlight and can cause greenhouse gas emissions, but with the Thermal GeoBubble Cover, this is prevented.

Noteworthy household savings are made on power, chemicals and water.

Installation Options

At the start of the construction of the swimming pool, different types of below ground systems can be chosen. The following solutions that can be offered. For every cover system, a covering of the cover pit can be provided.

  • In the cover pit behind the pool.

  • Inside the pool.

  • In a pit with a front panel.

  • In the bottom.

  • In cover housing.

  • In the steps with a upper panel.

  • In a recess in the wall.

  • Underneath the bottom with a removable lid.

  • Underneath the bottom with an automatic lid.

  • In the middle with an automatic lid

It is not always possible to install a below ground cover system on an existing swimming pool. The solutions are then above ground systems. The advantages of these systems are the optimal use of the operational length of the swimming pool and no need for complex adjustments to the structure of the swimming pool.

  • With side panels (without bench).

  • Removable (manual/automated).

  • Cover at height.

  • With solar powered motor.
