VISIBLENEAR INFRARED

The sun is burning at 5,700 degrees Kelvin, radiating solar energy
to the earth. In the solar radiation, energy of the ultra violet ray
accounts for only 3%, energy of the visible ray accounts for 47%,
and the rest 50% of energy is in the infrared ray.
Our target is to reflect the infrared ray as much as possible.

REFLECTION OF INFRARED
120

How does solar radiation affect the surface
temperature and heat flow through the roof?
When the roof surface is exposed to the sunlight, part of the solar radiation isreflected away by the surface substrate and the rest is absorbed. The absorbed
solar radiation heats the roof surface, and the heated surface partially emitsradiation in the far infrared part of the spectrum. The rest of the absorbed
energy passes through the roofing material into the room, which increases theroom temperature consequently. MIRACOOL is designed through the state-ofthe-art technology to have very high reflectance and extremely high emissionof solar radiation, and low heat conductivity in order to minimize the heat flow
into the room.
We have a vast of experiences and job records with regard to High Reflective
Coating i.e. MIRACOOL Series in Japan. Now, we are very pleased to introduce
MIRACOOL to other countries.

REFLECTION（%）

100BENEFITSReduction of surface temperature

Reduce cooling load and cost of air-conditioning systems up to 40 %in hot seasons. In a room without air-conditioning systems, the room
temperature can be dropped by up to 10 degree C. That helps working
environment and quality control of stored goods.

Protection of surface material

Extend the life of existing roofing materials.

Reduction of thermal shock

Reduce heat expansion of roofing materials that may cause loud noises.

Extraordinary weathering resistance
Reduce the maintenance cost of buildings.

WAVE LENGTH（nm)This graph shows the reflection rates of the 2 paints at every wave
length of the solar spectrum.
Both paints have the similar reflectance in the visible area, around35%, which means both look as Gray in the human eye.
However there is a remarkable difference in the infrared area
between the 2 paints: Miracool marks much higher reflection thana normal paint. This causes the difference of the temperature of thepainted surface.

To compare roof surface temperatureand room temperature, one section ofthe roof was coated with MIRACOOL(N6 Gray) and another section withnormal paint of the same color. Whilethe effectiveness of coatings on concreteroofs has been known to be relatively
modest, the measured difference in room
temperature was 2.2 ℃ . This demonstrates MIRACOOL's effectiveness in
reducing room temperature, even for
concrete roofs.

Temperature Measurement
Roof surface temperature and room temperature at apoint 1.6 m above the floor were measured by continuousrecording thermometers.

Comparison of Electric Energy Consumption
for Air Conditioning in Summertime
Not only did MIRACOOL cut electricity consumption, it also achieved room temperatures of 26–27°C when the air conditioning is set to26°C, in contrast to a temperature of around 30°C achieved for the same setting before MIRACOOL application, thereby creating a more
comfortable workplace environment. Furthermore, the cost of electricity usage has also been significantly reduced.
