2. Why use a pool cover?

3. Evaporation resource and
heat loss
By preventing evaporation 70% of the potential heat loss
can be prevented.
Why?
To heat 1 gram of water = 1 calorie of energy
To evaporate 1 gram of water = 540 calories of energy.
1 calorie = 4.186 joules the specific heat of water. This is
how a solar blanket is able to heat the pool so effectively.
Compared to an uncovered pool, gram for gram, the
energy savings are vast.
All Plastipack materials reduce evaporation by over 98%.

4. Insulation
The air trapped inside and between the bubbles
work as insulation.
400 micron Light Blue material.
Thermal information in different formats, R, U and
K values
The R value for Plastipack’s 400 Grade products is
0.06 m²K/W.
The overall thermal conductance or U value is
=
1
R
, which is 16.67 W/(m2K) for Plastipack’s 400
grade material.
From this a k value (Thermal conductivity) can also
be worked out, when R value is known.
𝑅 =

Thermal conductivity (k)
So k value is 0.00606 (W/K-m) for Plastipack’s 400
grade material.

5. Keep debris out of the pool
Keeping the cover on the pool not only keeps
the heat in the pool but also prevents foreign
matter from entering the pool.
Only 10% of the chlorine in a pool is used as
the active sanitizer to keep the water safe.
The other 90% is used as an oxidiser to
break down foreign matter in the water
caused by debris blowing in and bathing
loads.

6. It is of utmost importance that the material is maintained according to industry standards,
and should always be removed from the pool when shock dosing.

“I replaced my standard cover recently with a Sol+Guard™ pool
cover with GeoBubble™ Technology bubble design; the new
cover is really effective! I am very happy with the cover’s
performance and have already seen the temperature in my pool
increase by 3 to 4°C since replacing my old cover with the
Sol+Guard™ material.
The GeoBubble™ design seems much more durable and
thicker than my old cover and I have high hopes for it lasting
longer than my traditional cover on my salt chlorinated pool.
The Sol+Guard™ soft blue tint looks elegant on the water and
makes it hard to spot any residue from the water or dirt that
may rest on the top of the cover.”

10. Sol+Guard was designed and tested to allow the maximum solar energy to pass through the
material heating the water. Sol+Guard transmits nearly 80% of the sun’s energy into the pool,
heating the water and basin of the pool to provide an even temperature throughout the water.
The tests in the UK showed that a covered pool without any heating system can keep the
water at a comfortable temperature, keeping the need for additional heating at a minimum.

"As someone who has been in the pool industry for many years
I am always seeing new products making great claims as to
how good they are so it was with some doubt in my mind that I
tried the black EnergyGuard™ GeoBubble™ pool cover on my
own pool.
I put it on in September and did not put any winterising
chemicals at all in the pool. When I drew the cover back in May
I was delighted and, I have to admit, quite surprised to see that
the pool water was absolutely crystal clear. Just as I had left it
7 months ago. All the pool needed was one visit from my pool
cleaner and it was ready to swim in. I am highly delighted with
the algae-restricting performance of the EnergyGuard™ cover.
Not only did it give me a crystal clear pool, it also saved money
on winterising chemicals.
For the first time in 20 years I did not have to do any Spring
clean up in my pool."

14. How the material heats the water
Not all the potential energy available in the sun’s atmospheric window is absorbed by the
water before being reflected out of the pool. By using the EnergyGuard™ material, almost
all the light potential energy is captured and radiated into the surface of the pool. By running
the filtration or simply swimming in the pool, the free heat provided by the EnergyGuard™
material is quickly spread throughout the pool, raising the temperature by up to 4˚C.
©Plastipack 2014

15. How the cover saves chemicals
Photosynthesis uses the visible spectrum. By being opaque, the cover
inhibits photosynthesis, preventing outbreaks of algae in the pool. This in
turn minimises the amount of chemicals required as well as the pool's
filtration requirements.
Active chlorine is deactivated by UV light. By absorbing this energy, the
EnergyGuard™ material prevents the deactivation of the active sanitizer,
reducing the need for chemicals in the pool. EnergyGuard™ reduces
chemical demand by up to 70% and allows for a chemical-free shut down or
hibernation of the pool.

CoolGuard™ is an opaque material with a high reflective index in the visible and infra red
spectrum, keeping the sun's energy away from the pool and in turn reducing the temperature
by up to 15%.
Though the cover will insulate a pool if heating is used, the CoolGuard™ is ideal for hot
climates where a refreshing swimming environment is preferred.

20. How the material saves chemicals
Photosynthesis uses the visible spectrum. By being opaque, the cover inhibits
photosynthesis, preventing outbreaks of algae in the pool. This is turn
minimises the amount of chemicals required as well as the pool's filtration
requirements.
Active chlorine is deactivated by UV light. By absorbing this energy,
CoolGuard™ prevents the deactivation of the active sanitizer, reducing the
amount of chemicals required in the pool. CoolGuard™ reduces the chemical
demand by up to 70% and allows for a chemical-free shut down or hibernation

22. Storing the cover on a reel in direct
sunlight can cause the material to
deform and take the shape of the
reel, where after the cover will lose
its ability to lay flat on the water.
The material deforms as the
insulating properties of the cover
causes heat to build between the
layers which can reach a harmful
level.
To prevent this, Plastipack
developed the reflective cover to
allow ease of storage when not in
use.
Using the reflective cover as
protection, the internal temperature
of the material can be reduced by
up to 30°C.

The new design removes residual stresses from the material, creating a more durable, longer
lasting bubble. Unlike most standard 12mm bubble designs, GeoBubble™ technology has
been engineered specifically to survive the swimming pool environment.
