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.
