swimming pool insulation

Compass Pools has developed an innovative insulated swimming pool design that we refer to as a passive pool. As an experienced specialist in swimming pool design and installation, we are always looking for advances in technology that provide a better quality product for our customers. This led us to investigate different methods of pool insulation and eventually create our passive pools.

The concept of the passive pool originates from a trend in housebuilding where something called a ‘passive home’. A passive home is achieved using highly sophisticated thermal insulation that allows for comfortable living temperature to be achieved with minimal heating required. One important aspect of the passive home is that it is made vapour-impermeable so ventilation can be mechanically operated with heat recuperation. Using our construction background and experience, we have utilised these ideas to develop the passive pool.

What are the features of the passive pool?

Our passive pools have a range of specific structural features:

  • 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 – roughly 40kg per m³
  • Chemically inert – ensures that the insulating properties do not diminish in time due to 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 also ensures that the pool is perfectly sealed. The Compass passive pool uses Bi-Luminite® coating technology, combined with a sealed ceramic core

What sets the Compass passive pool apart?

  • No thermal bridging means heat cannot escape through gaps in the insulation as with a paneled insulation system and is 100% air tight. 
  • Insulation is 10mm from the water, meaning there is no thermal mass to heat up – traditional concrete pools will require 2.5x more energy to heat both the walls and the water.
  • The insulation is not covered by a liner or tiles, meaning there is no risk of damage through indentation from impact.

Better for the environment

At Compass Pools we strive to match our commitment to superb value to customers with our respect for the environment. Alongside the solar roll-out cover, the CFC-free insulation layer makes sure that heat loss is kept to a minimum. This means that you don’t need to use lots of energy constantly re-heating your pool. The energy needed to heat the passive pool is drawn from the outside air with a high-performance heat pump. With an outside temperature of between 15°C and 25°C, for every kWh consumed from the grid, between 5 and 6 kWh are put into the pool water. This keeps your carbon footprint down and also saves you money on your energy bill.
