What is a CoolGuard cover?

A CoolGuard cover is an innovative swimming pool bubble cover material that is sold in roll form to fabricators around the world for commercial and domestic use.

The product has an opaque light blue top surface and a black underside. It is this combination that gives a CoolGuard cover the ability to provide a variety of benefits to the end-user. This ranges from keeping the pool cool and reducing maintenance costs, to the personal desire to save natural resources and the practicalities of reducing electricity and water usage.

The tough durable 500 micron pool cover materials used for EnergyGuard, CoolGuard and Sol+Guard are formulated for climate conditions in various continents of the world depending on UV (ultra violet) weathering intensity.  The Sol+Guard and EnergyGuard materials are supplied in two UV formulations: one for areas up to 140 kLys/yrs (Kilolangley years) and one for up to 180kLys/yrs.  CoolGuard is supplied for areas up to 180kLys/yrs. The additives we use combine weather and chemical resistant pigments with high performance light, weather and chemical stabilisation. The additives are non-toxic and registered in Australia, Canada, China, EU, Japan, Korea, Philippines and USA.

Reflect the sun’s heat away from the pool

The colour white is known to reflect the sun’s heat in a very efficient way. Plastipack has carried out research and produced an opaque reflective light blue colour with similar characteristics. The sun’s heat is reflected away from the surface of a CoolGuard cover and allows the water surface area directly under the cover to stay cool and refreshing for you to enjoy.

The CoolGuard cover will provide a thermal barrier to prevent the absorption of the sun’s energy.

Inhibit Algae Growth

The CoolGuard cover has the unique ability to inhibit algae growth and reflect the sun’s heat from the pool water on outdoor swimming pools.

A Plastipack CoolGuard cover will inhibit the light from entering the water, therefore stopping photosynthesis and inhibiting algae growth.

Research and scientific tests proved that the CoolGuard cover inhibits algae growth even without chemical treatment.

Inhibiting algae growth offers many advantages to the pool owner including reducing the risk of eye, ear, skin and gut infections, avoiding slippery surfaces, reducing filter blockages and improving the aesthetics of the water.

Tests prove that the CoolGuard cover works

The pools in the images were both tested for ten days with no
chemical treatment, no filtration and with simulated use. The pool shown in the left hand image had a standard solar gain cover and soon went green due to algae growth. The image on the right shows a pool with the Plastipack CoolGuard cover with no algae growth. The test was continued for two months and this pool still remained clear of algae when the test period ended.

Reduce Filtration/Pump Time by up to 50%

Filtration time can be greatly reduced because algae growth is inhibited when a CoolGuard cover is on the pool. Filtration will still be required to remove dirt (impurities) from the pool and to circulate the water, but this could be cut by up to 50%. This is achievable with regular pool use/bathing loads, but if there is heavy use of the pool there will need to be greater filtration.


Eliminate Water Evaporation by 98% +

With a CoolGuard pool cover you will be able to eliminate water evaporation by over 98%, thus greatly reducing your water consumption and your water charges, as well as saving a vital natural resource. Plastipack carried out research, in collaboration with the Brighton and London Metropolitan Universities, which proved that the evaporation loss in the UK for an average sized pool, 4m x 8m, is approximately 32,000 litres per year. This figure is considerably higher for hotter climates.

Reduce Chemical Consumption by up to 60%

Reduce chemical usage by inhibiting algae growth and eliminating evaporation when a CoolGuard cover is in use.

A CoolGuard cover will provide cost savings by using less chlorine because algae growth will be inhibited by physical means rather than chemical means. The CoolGuard cover also reduces chemical degradation from photolysis. About 90% of chlorine consumed by outdoor pools is lost due to photolysis reaction.

Additional cost savings will be made by using less pH plus/pH minus to correct any pH imbalance caused by algae. All pool chemical levels and treatment should be maintained at the manufacturers recommended level.

Reduce Energy Consumption by over 50%

A CoolGuard cover will eliminate evaporation and greatly reduce radiation. Plastipack’s heat retention tests carried out in collaboration with the Brighton and London Metropolitan Universities, showed conclusive energy savings of over 50%.
This applied to oil, gas, electric heater or heat pump usage. Where solar heating is used, it is possible to invest in up to half the amount of panels normally required for a pool without a cover.

Reduce Debris Contamination

Debris such a leaves, dirt, insects and bird droppings are not only unsightly in a pool but also provide nutrients for algae and bacteria to feed on. When the pool is covered these contaminants will be kept out of the water, greatly improving the quality and appearance of the water.


Save Money

A CoolGuard cover will save money by reducing water, energy, cleaning and chemical costs. The CoolGuard pool cover will pay for itself in less than a year.



The CoolGuard cover has a 5 year pro rata warranty. The Sol+Guard™ and EnergyGuard™ materials are supplied in two UV formulations that are covered by our pro rata 5 year warranty.


Environmental Benefits

By reducing the amount of energy needed to heat and filter your pool water, a CoolGuard cover will greatly reduce your CO2 footprint. It also conserves water and, at the end of its life, a Plastipack cover is 100% recyclable.
