Solar Covers

Bubble Swimming Pool Covers:

Are Generally produced using two ply’s of polyethylene material with additives to colour, help strengthen and protect against, UV (Ultra Violet) light, the suns heat and pool chemicals. The bottom layer is generally formed into air cells that help insulate, support / float on the surface of the pool water. The flat top surface is normally co-extruded or laminated to the bottom layer to form a flat surface.

Heat Retention, EnergyGuard, Energy Absorbing Bubble Covers:

Are generally produced using opaque darker colours that do not allow the sun’s energy/light to pass through. This type of heat retention / energy absorbing covers can be used for outdoor / indoor pools. Or commercial pools that are mainly in use during the daytime.

Heat Reflective, CoolGuard™ Bubble Covers:

For hot climates, are generally produced using light reflective opaque colours that reflect the suns heat away from the pool surface, this process reduces the amount of solar energy to pass through the cover,  allowing the pool water to be cooler and more refreshing to swim and enjoy.


Solar Pool Bubble, Sol+Guard Covers:

Are generally produced using a very light colours such as transparent light blue. This allows the sun’s solar energy, short wave solar energy to pass through. Heat retained in the water, which radiates at the longer wave lengths, are restricted by the cover so can’t readily dissipate into the surrounding atmosphere. The Plastipack Solar pool bubble cover material heats the water (and retains the heat) by up to 8 degrees Celsius.

How Pools Loose Heat

Pools loose heat in a variety of ways, but evaporation through the pool surface area is by far the greatest source of energy loss for swimming pools. When compared to evaporation, all other losses are small.

The reason evaporation has such an impact is that evaporating water requires tremendous amounts of energy. According to information from the U.S. Department of Energy, it only takes 1 Btu to raise 1 pound of water 1°F, but each pound of 80 °F water that evaporates takes a very large 1048 Btu's of heat out of the pool. The metric equivalent means that it takes 0.001163 kilo watt hour of energy to raise one litre of water 1°C and each litre of water at 27°C that evaporates wastes 1.218 kWh of energy.

Why Plastipack Bubble Pool Covers

Since evaporation is the major source of heat loss for all swimming pools, to minimise evaporation one must cover the pool. Covering the pool with a Plastipack pool cover that suits “your needs”, when it is not in use is the single most effective means of reducing:

  • Energy consumption by over 50%
  • Reduce chemical consumption by up to 60%
  • Eliminate water evaporation by 98% +
  • Increases pool temperature by up to 8 degrees C
  • Inhibit algae growth
  • Reflect/Absorb the sun’s heat
  • Reduce filtration/pump time by up to 50%
  • Reduce debris contamination


Outdoor Pools

The chart below illustrates the impact of evaporation on the total energy consumption of the outdoor pool.

Energy Loss Characteristics

Radiation to sky 20%
Losses to the Ground & Other 10%
Evaporation 70%

The evaporation rate from an outdoor pool varies depending on the temperature of the pool, the temperature and humidity of the air, and the wind speed at the pool surface. The higher the pool temperature and wind speed and the lower the humidity/air temperature, the greater the evaporation rate. Plastipack Evaporation Prevention Report

Indoor Pools

The next chart illustrates the impact of evaporation on the total energy consumption of the indoor pool.

Energy Loss Characteristics

Ventilation 27%
Other 3%
Evaporation 70%

When we compare outdoor and indoor energy loss characteristics, energy loss vehicles may change, but the percentage for evaporation remains high.

Indoor pools are not subject to the high fluctuations in day and night temperatures of outdoor pools. Neither do they radiate heat to the night sky, or have winds that carry heat away from the pool; but they do require room ventilation to control indoor humidity caused by the large amount of evaporation. Without a proper ventilation system, high indoor humidity levels will cause numerous problems, including condensation on cold surfaces and corrosion/ deterioration of structural components.

The energy required to run a ventilation system adds to the costs of operating an indoor pool. Also the ventilation air must be conditioned, which adds further to the costs.

When To Use A Pool Cover, Domestic Or Commercial

To gain the maximum benefit from your Plastipack bubble pool cover, the general rule of thumb is: a cover should be placed over the pool water surface area as soon as it is not used and enjoyed, and taken off just before you would like to enjoy and swim.

Environmental Benefits of your Plastipack cover

By choosing the Plastipack cover that suits your needs, you can reduce the amount of energy needed to heat and filter your pool, eliminate water evaporation by 98%+, inhibit algae growth, increase solar energy, reduce chemical consumption and debris contamination you will greatly reduce your carbon footprint, and at the end of its life, a Plastipack cover is 100% recyclable.
