The school next to us
used to be very noisy,
but after applying the
Energy Coating we
barely even notice it’s
there anymore.
On top of that, after
applying the coating
we have noticed that
we use the A/C much
less and as a result our
bills have dropped
tremendously.
Reasons for choosing Keisoukun Gaina:
”
The attic was turned
into a spare room and
the roof and walls were
coated with the Energy
Coating. Now the 3rd
floor is cooler than the
2nd floor.

For the exterior coating, in
the summer even during the
night we could feel the heat
on the west side of the
building. When the sun rose
it was even worse but after
applying the paint. We don’t
need to have the A/C on at
night anymore. Just the
breeze from the widow is
enough to keep the
environment comfortable.
As far as the interior
coating, although we have
only painted 1 room so far,
we have noticed a huge
difference in the sound from
the coated room compared
to an uncoated room.
In 2005 the reflection
from the roof and the
heat simply made the
roof unusable. The
Energy Coating cured this
problem for us. Even
when walking with bare
feet on the roof we can
hardly notice any heat.
Now we have added a
slide for kids and a
walking area for pets on
the roof. The roof is now
very comfortable.

Every summer our factory
and warehouse used to
suffer from the most
extreme heat. The factory
workers would have to
constantly take breaks just
to avoid the heat.
After installing the
coating we found that it
went without saying that
we saved money on the
electric bills but even more
than that our overall
productivity skyrocketed.
Reasons for choosing Keisoukun Gaina:
”
Originally we wanted to
use the coating as an
attempt to reduce the
condensation that was
building up in our
warehouse on the
beams.
Keisoukun Gaina not
only solved this but also
after painting the roof
and ceiling we are able
to spend our summers in
a relaxed and
comfortable work
environment.

We used the coating on our
factory’s western wall as
well as the roof. In the
western area of the factory
we noticed a big change
right away. The entire area
became much more
pleasant. Before we were
using 7 out of 7 cooling
units for the factory but
after applying the coating
we now only use 5. We
have been able to save so
much on our airconditioning bills.
Reasons for choosing Keisoukun Gaina:
”
We used the product on
our factory’s roof and
besides the heat
reduction the other
thing that surprised us
was the way that our
white factory roof
would gleam after it
rained almost looking
like a brand new coat
of paint.

Before we were using 16
air conditioning units to
cover the entire store but
after applying the coating
we scaled that back to only
10 and the other units are
not needed to cool the
building.
We painted the roof and
the exterior walls and the
previous yearly electricity
bill was JPY3,400,000 and
now its JPY2,100,00/ year.
That is a 39% savings. In
about 3 years the savings
had fully paid for the
product and installation.
Reasons for choosing Keisoukun Gaina:
”
Even with the temperature
set on 29°C we never needed
to change the temperature
in the summer. Our store use
to be so hot and with the
doors opening and closing
all day it was hard to
maintain a comfortable
temperature. After installing
the coating we were just
amazed at not only the
bonus in cost reduction but
also the way employees
attitudes improved. This
was not only felt by upper
management but also the
customers noticed too.

After painting the office
with Keisoukun Gaina
the situation improved
greatly. In summers
with we set the
temperature to 29-30°C
and in winters we set it
to 25°C and leave it.
Our office is next to a
really busy street and
we don’t notice any
outside noise anymore.
Reasons for choosing Keisoukun Gaina:
”
We used to be able to
really feel the heat
when we would have to
go to the top floor.
Before we used it as a
storage room but now
we can actually work
on that floor. On top of
that we barely hear the
rain on stormy days
now.

Hot in the summers and
cold in the winters, our
office was unbearable.
After we painted with
Keisoukun Gaina we
noticed a huge difference
immediately. The
temperature just dropped
almost as if by magic. Not
only did this get our mind
off of how hot or cold it
was but on our work, it
also all but blocked out the
noise from the rain or the
traffic.
Reasons for choosing Keisoukun Gaina:
”
When it is hot outside
and I enter the office,
even without the air
conditioner on I would
get a cool feeling.
Now during summers
the thermostat is
always set to 28°C.

There is a big issue with
storage of unused construction
materials such as wood. These
materials are often stored in
warehouses and scrap yards
awaiting disposal. Heat plays
a big part in the storage of
these materials. Some of the
materials that we use are
stored in our building and we
must constantly keep the air
conditioner on to maintain a
good environment.
With Keisoukun, we no longer
have to keep the system as
high as we once did. This has
saved us lots on our energy
bills.
Kumamoto gets pretty
cold in the winter so we
heard about the product
and the ability to maximize
the heater/Air
conditioner’s effects when
painted on the interior.
When we turn on the
heater now it only takes a
fraction of the time for the
room to heat up and it
stays like that even well
after we have turned off
the heater.
