What is GAINA

GAINA is a thin-film insulation material created using Japanese space rocket development technology.
GAINA is the only coating material that has an insulating effect even in winter.

The Japan Aerospace Exploration Agency (JAXA) developed a heat insulating technology to be applied to the tip (fairing) of the H-II rocket to protect the vehicle and satellite from heat during launch.
Nissin Sangyo Co., Ltd., which has been independently researching and developing heat insulating coatings, has applied this heat insulating technology developed by JAXA to develop "GAINA", a "heat insulating ceramic coating" that is lightweight, has excellent heat control properties, and can insulate simply by applying it, so that it can be used in the daily lives of ordinary people.
GAINA is an insulating coating that realizes "controlling heat transfer with a thin film", and has attracted attention from various industries not only in Japan but also around the world.

Paint ceramic

GAINA is a revolutionary coating material that not only insulates and blocks heat, but also improves various complaints about the home environment simply by applying it. The secret that sets it apart from other coating materials is the effect of special hollow ceramic beads.

GAINA is a paint made by using unique technology to successfully turn special ceramic beads, which have excellent insulating properties and far-infrared radiation characteristics.

As a result, it not only provides insulating effects that defy conventional wisdom, but also exerts a variety of other effects, dramatically improving the performance of your home.

Performance comparison between conventional coating materials and GAINA

Just paint
however it's NOT a PAINT

GAINAs exceptional qualities stem from its unique hollow ceramic beads, which make up to 80% of the coating once dried.
These beads form an extremely robust film, providing a lifespan 2-3 times longer than standard paints, ensuring lasting effectiveness.
Our patented technology has also advanced this ceramic to achieve the ease of application comparable to regular paints.
Additionally, GAINA offers excellent fire resistance and is a water-based, non-toxic substance, free from harmful chemicals.

Four Key Functions

(1) High Reflectivity

・Reflects 90% of near-infrared rays from sunlight
・Reduces heat generation on the coating surface by reflecting thermal rays

(2) High Emissivity

・Radiates 95% of absorbed heat as far-infrared radiation
・Releases heat from the coating, lowering surface temperature

(3) Low Thermal Conductivity

・Low thermal conductivity reduces heat penetration,enhancing insulation

(4) Low Specific Heat Capacity

・Specific heat capacity similar to that of air
・Prevents heat retention, allowing air flow to naturally　dissipate heat and lower temperature

GAINA’s surface reflects near-infrared rays to suppress heat reactions, while it absorbs and re-emits far-infrared rays, enabling precise thermal control.

Due to its very low heat capacity, the coating heats up and cools down rapidly.
When not exposed to intense infrared radiation, the surface temperature of the coating instantly equalizes with the surrounding air temperature.
This property applies not only to air but to any object that comes into contact with the coating; if an object with a larger heat capacity touches the coating, the contact temperature quickly equalizes.
Heat transfer does not occur between surfaces or fluids that are at the same temperature.

Thus, GAINA minimizes heat transmission by maintaining thermal equilibrium, effectively reducing heat flow through assimilation and balance.

Case Study at Nad Al Sheba

The thermal imaging comparison at Nad Al Sheba clearly shows the effectiveness of GAINA coating on rooftops.
The coated rooftop recorded a temperature of 40.7℃, significantly cooler than the 59.6℃ measured on the uncoated rooftop, resulting in a difference of 18.9℃.
This evidence highlights GAINA's ability to reflect heat, contributing to improved energy efficiency and thermal comfort in urban settings. By maintaining cooler surface temperatures, GAINA can help reduce air conditioning costs, enhance the longevity of roofing materials, and create a more comfortable living environment for occupants.

Dubai Municipality Nursery

The sampling at the Dubai Municipality Nursery highlighted the effectiveness of GAINA’s formulation. It demonstrated a significant reduction in maximum surface temperatures, with the temperature dropping from 69.9℃ without GAINA to 59℃ with it—a difference of 10.9℃.
GAINA’s ability to absorb 95% of UV rays not only reduces health risks associated with skin and eye irritation but also protects underlying materials, extending surface durability to approximately 15 years.
This study confirms GAINA's role in effectively managing heat absorption and enhancing surface performance in Dubai's challenging climate.

Frozen refrigerated storage – Maskar

The implementation of GAINA has led to significant operational improvements in the freezer room. Firstly, the number of air conditioning units required has decreased from 8 units to 4 units, indicating enhanced thermal efficiency. Secondly, the contracted power demand has been substantially reduced from 960 kWh to 380 kWh, reflecting a more efficient use of energy. Lastly, these changes have resulted in a 50% reduction in annual electricity costs, underscoring the economic benefits of adopting GAINA's advanced heat management solutions. Overall, these improvements contribute to a more sustainable and cost-effective operation.

Long Lasting Performance

The implementation of GAINA has led to substantial long-term benefits over a 10-year period, with estimated electricity cost savings of 2.8 million yen.
Additionally, the temperature on the second floor has been reduced by 15 degrees Celsius, allowing for a significant decrease in the number of air conditioning units required—from 4 units to just 1.
Furthermore, the need for spraying water on surfaces during the summer has been eliminated, simplifying maintenance.
Importantly, the effectiveness of GAINA's heat management properties has been sustained even 10 years after installation, demonstrating its lasting impact on energy efficiency and operational costs.
