Engineered for Efficiency

Energy efficient, insulated pools designed from the ground up

Using our specialist knowledge of swimming pool design and installation, our expert team at Compass Pools have developed an innovative insulated swimming pool design known as a ‘passive pool’. We are always on the lookout for technological advances that can provide better quality products to our customers. This passion led us to look into various types of pool insulation, which eventually led to the creation of our passive pools.

Passive Pool

The concept of the passive pool originates from the ‘passive home’ trend commonly associated with housebuilding. To achieve a passive home, a highly sophisticated form of thermal insulation is used to create a comfortable living temperature which requires minimal heat. In order to achieve this though, the home needs to be vapour-impermeable to allow ventilation systems to recuperate heat and be operated mechanically.

Through our construction background and experience, we took these ideas and utilised them to develop our very own passive pool.

What are the Features of the Passive Pool?

Our passive pools have a range of specific structural features, including:

  • Highly insulating – the polyurethane insulation material we use is CFC-free and has a thermal conduction coefficient of 0.026 W/mK.
  • Closed cells – minimum 90% according to the Remington method.
  • Compression stress of 250 kPa at 10% deformation
  • Density – approximately 40kg per m³.
  • Chemically inert – this ensures that the insulating properties do not diminish over time as a result of chemical or organic degradation processes.
  • Waterproof outer wall – a dual-component waterproof layer is applied to the outside of the insulation package to prevent diffusion and osmosis.
  • Closed structure of the inner wall of the pool – following the same vapour-impermeable character of passive home designs, this structure ensures that the pool is perfectly sealed. Our passive pool combines Bi-Luminite® coating technology with a sealed ceramic core.
