33. Incombustibility

GAINA is certified incombustible by the Ministry of Land, Infrastructure, Transport and Tourism, a Cabinet of Japan.

To ordain incombustibles by the government ordinance, there are 3 ranks of building materials to fit in the engineering standards for incombustibility: Incombustibles, Quasi-incombustibles, Fire retarding materials.

GAINA is certified as an incombustible (in Japan), the highest rating possible by Ministry of Land, Infrastructure, Transport and Tourism.

32. Safety

Water-based GAINA is safe. Interior GAINA received a "Four Star" grade (in Japan.)

Water-based GAINA does not contain hazardous materials such as organic solvents. Interior GAINA received Four Stars for the room air quality safety measurement.

Also, GAINA can be used as exterior paint, it cannot receive Four Star (because it is an interior rating system) but it holds the same level of safety evaluations for aldehydes and Volatile organic Compounds (VOC) as seen in the table below.

31. Endurance

GAINA can make buildings' last longer.

Regular Paint (left)                 GAINA (right)

GAINA has many ceramic layers that are the strongest against ultraviolet rays, and is 2 to 3 times more durable than regular paint. Also, its insulation/thermal barrier effects restrict the building's usual expansion/contraction.

30. Preventing Condensation

Dew prevention

Preventing condensation by restraining the movement of heat, creates a comfortable living situation.

There are many places - ceilings, walls, windows, in the closet - in our home where condensation occurs. Condensation happens when the heat of the air moves through windows and walls. Heat moves from higher temperatures to lower temperatures. This is why condensation happens in the lower temperature areas such as windows, walls, and closets.
GAINA's coating adjusts to the surrounding temperatures. So when painted with GAINA, the surface area's temperature becomes comparable to the room temperature. As a result, there is less movement of heat because there is less difference in temperature, and the effect of preventing condensation happens.

29. Preventing dust to float and stick

Preventing unpleasant odors and controlling dust particles that stick to walls and ceilings.

Most solid particles (odor molecules, pollutants, dust, pollen, etc.) in the air are positively charged. This makes them stick to surfaces by static electricity.

How GAINA works

Pollutants have difficulty clinging to GAINA coated surfaces. (GAINA has 0.0 electrification characteristic)

GAINA as a purifier:
The negative ionized water attach to floating particles, and won't stay in the air.

For clean air, Negative Ion Balance is necessary.

An interior with GAINA Coating has the proper balance between Positive and Negative Ions.

28. Air Quality Improvement

Odor neutralization (Odor control)

A restaurant improved odor

Applied / inside walls
592 ft²  (55 m²)

Mr. S, owner of a small Japanese restaurant (Fujisawa city Japan) chose GAINA. He said "If the air is clean, food and drinks taste better. I wanted to create a relaxing, hospitable atmosphere" In his new restaurant, GAINA was coated on all the interior walls with a plaster style finish creating a calm refreshing environment. The most surprising to him was "there was no residual smell of alcohol and cigarettes from the previous day" He said "I'm likely to forget the ventilation."

Restaurants must keep clean for safety reasons. Guests won't eat or drink if the restaurant appears unclean. Likewise, providing clean, fresh air has become more popular, since restaurants are prone to odors. The smell remains after closing because it sticks to the walls and ceiling. GAINA has the ability to prevent dirt and odors from sticking. Mr. S couldn't believe how well GAINA worked, it was better than expected.

Almost like being in the forest, realized that air quality improved

T's home Application : inside walls / ceiling
1808 ft² (168 m²) / 1883 ft² (174.9 m²)

T's family (in Fukushima prefecture Japan) coated GAINA on their new house because their previous home was dusty. When they moved into the new house, immediately they felt the air-quality difference. They said "It feels like we are living in the woods."

M's home : inside walls / ceiling
484 ft² (45 m²) / 376 ft² (35 m²)

Mr. M (in Tokyo) was bothered by unpleasant smells of the previous home owner. After he renovated his condominium, he was pleased, saying, "After GAINA was applied, no more bothersome smells and very comfortable."

F dental clinic : walls and ceiling
1808 ft² (168 m²)

Dr. F, a dental director (in Fuji city Shizuoka prefecture Japan) coated GAINA in his clinic to improve air quality and help patients relax.
Now he gets nice comments from the patients saying, "It's comfortable."

Sound meter

Result of hitting hammer sound was:
    Ordinary frying pan - 94.7 dB
    GAINA frying pan - 74.9 dB

    Reduction - 19.8 dB
 
     20 dB - 1/100 the power
       6 dB - 1/4 the sound

94.7 dB

74.9 dB

26. Vibration Testing

GAINA quickly absorb vibration

Sound is a vibration that is transmitted through a medium such as air.
The sound coming through the wall means that sound vibrates the wall in turn vibrating the air on the other side.

There are 3 data forms of Vibration Testing from Hamamatsu Industrial Research Institute.
This test shows how much GAINA suppresses the vibration.

Fabric without paint

Phthalic Acid Paint

GAINA

Result:
Test data in the figure above, clearly show that GAINA has soundproof effect by suppressing the vibration.

25. Soundproof

Special Ceramic Beads in GAINA reflect sound and suppress vibration.

GAINA coating(membrane) is made up of multi-layered hollow ceramic beads containing air inside.

The structure of the ceramic beads reflects the sound and the air within absorbs the vibration.

Thus GAINA has a soundproofing effect. When the sound enters the film, the multi-layer ceramic hollow beads reduce the sound by suppressing the vibration.

24. Noise Reduction

Soundproofing - Busy street sound effect

Reducing traffic noise, my family now enjoys conversation.

Application for K's home
Inside Walls & Ceiling: 430 ft² (40 m²)
Outside walls: 2800 ft² (260 m²)

"We used to turn the TV volume up very high so we can hear it" says the K family living in the suburb of Hamamatus City, Shizuoka prefecture, Japan. Their house is on a busy street with high speeds. Also, there is a Heavy Equipment and Truck Rental Company across the street from their house, making loud noise, such as engine sound. It was GAINA that solved the K family's trouble. Coating GAINA on all the exterior walls of their house greatly reduced the noise pollution. Even in the living room that faces the busy street, they are able to watch TV set at a normal volume level. "Now we hear voices that we couldn't hear before in the noise, and enjoying our family conversations" says Mr. K with a smile.


The room is so quiet, they don't notice the sound of rain.

Application for O's home
Roof: 978 ft² (90.9 m²), Outside walls: 1689 ft² (156.95m²)

Application for T's home
Inside Walls: 426 ft² (39.6 m²), Ceiling: 213 ft² (39.6 m²)
Outside Walls: 888 ft² (82,5 m²)

O family in Kanazawa prefecture chose GAINA because every year their children complained that "Our room on the 2nd floor is so hot." After Coating GAINA, not only did the temperature drop significantly, but also they noticed less noise. "Sometimes we have to hurry to get our laundry from outside because we don't notice the sudden shower" says Mr. O.

T family in Suka city, Saitama prefecture had trouble with noise because their house is in a noisy shopping district, and there is a lot of traffic. "After we painted GAINA, we realized how quiet it is in the house. We don't even notice the noisy cars and people that we used to hate" says satisfied T family.

23. "Feel Like" Temperature with GAINA

Ordinary House                                              GAINA House
68˚F (20˚C)                  Room Temperature     68˚F (20˚C)
86˚F (30˚C)          "Feel Like" Temperature     68˚F (20˚C)

___________________________

"Feel Like" Temperature

(Temperature + Emitted Heat) ÷ 2 = "Feel Like" Temperature 

Ordinary house / Indoor Temperature setting - 68˚F (20˚C)
The outside heat penetrates the walls and ceiling.
When walls and ceiling surface temperatures are 104˚F (40˚C)
The "Feel Like" Temperature is 86˚F (30˚C).

(68˚F (20˚C) + 104˚F (40˚C)) ÷ 2 = 86˚F (30˚C)

GAINA coated interior / Indoor Temperature setting - 68˚F (20˚C)
The surface temperature of the walls and ceiling adapt to 68˚F (20˚C) Therefore both the room temperature and the "Feel Like" Temperature are 68˚F (20˚C).

(68˚F (20˚C) + 68˚F (20˚C)) ÷ 2 = 68˚F (20˚C)

The difference is lowered by 18˚F (10˚C).

22. Air Conditioning Improve in Summer

Ordinary House                                            Coated GAINA

 "Paint the interior to improve insulation"
_________________________

When the indoor temperature is lower, outside heat penetrates through the walls and ceiling.
After applying GAINA to the interior walls and ceiling, the GAINA surface adapts to the air conditioned temperature setting immediately to minimize heat transfer and maximize energy savings.

21. Temperature Difference with other Paint

GAINA reflects and prevents absorbing heat, keeping temperatures inside cool during Summer.

Right (GAINA)        -   92.5 °F  (33.6 °C)

Prediction: Based on the data
The room temperature drops 9 °F (5 °C)

20. GAINA's heat prevention mechanism

The Sun's infrared rays reflect, bend and move on the surface of GAINA's ceramic beads repeatedly, thus reducing the heart entering the house (see the graphic on the left).

Inside the ceramic beads is another layer of heat resistant materials that also reflect the sun's rays.

19. Barrier Against Heat

A house once depending　on an air-conditioner is now cool without it.
Many people have experienced the heat barrier effect of GAINA Coating.

Mr. M's home
Roof / 1400 sq ft (130 m²⁾ 
Exterior / 1507 sq ft (140 m²⁾ 

Mr. M (Tokyo, Japan)

"It was so hot we needed the air-conditioner 24 hours a day"

When GAINA was recommended by a friend because of its high performance thermal barrier effect and easy application, Mr. M applied it to the roof and exterior walls. Inside the house, the temperature was astonishingly cooler.

Mr. K's home
Inside walls & ceiling / 430 sq ft (430 m²⁾ Exterior / 2800 sq ft (260 m²⁾ 

Mr. K (Shizuoka prefecture, Japan)

"I no longer feel the heat as much during the summer."

Mr. T's home
Roof / 3230 sq ft (300 m²⁾ 
Exterior / 1938 sq ft (180 m²⁾ 

Mr. T (Aichi prefecture, Japan)

He couldn't tolerate the heat of the second floor in his house before using GAINA. After the application, he states.
"There is no big difference in temperature between the first and second floor anymore.
I can just open the window and it feels cool"

Mr. S's home
Roof /1102 sq ft (94 m²⁾ 
Exterior / 1507 sq ft (140 m²⁾

Mr. S (Ibalaki prefecture, Japan)

He remeasured the temperature of his roof after it was coated with GAINA. He excitedly commented.
"I was surprised to see that roof temperature dropped over by 50°F(28℃)."

18. GAINA Against Heat

The insulating effects of GAINA Coating throughout the year makes the air in any room very comfortable, it feels smooth and dry, even during the humid summer months.

Applied area
Interior/ceiling 415 m² (4467 sq.ft)
Roof 160 m² (1722 sq.ft)
Exterior 175 m² (1884 sq.ft)

The Y couple built a resort-type cottage in Aichi prefecture Japan. Both the exterior and the interior walls and ceilings were coated with GAINA. When they first went inside the new house, the freshness of the air was the first thing they noticed.

"The air is not at all humid even without the air conditioner running, it is so comfortable." says Mr. Y. "Even the dehumidifier couldn't collect any water from the air." he states. 

GAINA's moisture impermeability combined with the natural wood has created this freshness. For this couple, the effect of preventing summer heat and humidity was more than they expected. In the Y's previous home (not coated with GAINA) it generally felt hot and humid even with the air-conditioner constantly running. But now, they are comfortable in their new home, and hardly use the air-conditioner either.

 "Every day is so comfortable, thanks to GAINA." exclaim the satisfied couple.

17. GAINA helps improve your sensory temperature

GAINA helps improve your sensory temperature. 

 Left - Before                                                                                                 Right - After

The temperature in both rooms is set at 86°F (30℃).  

In the room without GAINA coating, the surface temperature of the walls and ceiling is measured at 50°F (10℃). The sensory temperature of the person is only 68°F (20℃). 

The GAINA coated room on the right has a surface temperature of 86°F (30℃) on the walls and ceiling. The sensory temperature of the same person in this room is 86°F (30℃).

16. GAINA Coating Inside

Painting the interior of your structure with GAINA Coating will improve heat retention.

       Left - Before                                                                                                 Right - After

The heat will escape through the walls and ceilings when they have lower temperatures. With GAINA coated on the interior, the temperature of the walls and ceiling will adapt to the air temperature, minimizing the heat's movement through the surface.

15. Paint the exterior to prevent heat from escaping

Exterior GAINA Coating prevents the heat from escaping in cold weather.

With GAINA on the exterior of a structure, the surface adapts to the surrounding temperature, creating equalibrium between the surface and the surrounding air temperature. This results in minimized heat transfer. Simply put, GAINA keeps the cold outside, and the heat inside.

14.Temperature Adaption Experiment

GAINA adapts to the surrounding temperature.

       Left - Regular Paint  / Right - GAINA

Two Iron Plates

• Plates are placed side by side.
• Left coated with regular paint.
• Right coated with GAINA.
• Hot air blown at the center of the model.   

This is done to ensure that each plate gets the same amount of air at the same temperature.

5 seconds passed

Surface Temperatures Change

These images show the changes as seen from a thermographic imager.

• On the right, the GAINA plate temperature increases rapidly.
• On the left, only a hint of change.

another 7 seconds pass

After just 12 seconds

• The GAINA plate is nearly all the same temperature as the heated air.
• Meanwhile, the temperature of the regular painted plate is just starting to rise.

Air Temp Switch

7 seconds of cool air

The hot air was then switched to cold air. This demonstration shows how a GAINA coated surface adapts to surrounding air temperature. After a mere 7 seconds the temperature of the GAINA plate dropped significantly.

• The regular painted surface is still very hot.
