3. far-infrared

Gaina is a complex product with many benefits. One of these is it's protection against solar radiation. Gaina reflects 90% of sunlight by refraction (prism) and reflection, and radiates 95% of far-infrared from absorbed heat. Because of the high rate of far-infrared radiation, Gaina controls thermal conduction very well.

Sunlight has ultraviolet rays, visible light and infrared rays. Infrared has near-infrared and far-infrared. Solar radiation that doesn't reflect, through the atmosphere, then reaches the surface. It raises the substance temperature, turns to thermal energy and radiates far-infrared. About 30 % of radiation reflects back into space (depending on the area). Such energy balance maintains average temperatures on the earth. All materials except metal emit far-infrared rays. Higher temperatures produce more radiation, and ceramic beads radiate a lot of far-infrared.

Gaina contain 80% ceramic that has a high radiation performance. It brings a superior performance for heating and cooling energy savings. Outside coated with Gaina cools inside during summer and improves the outside environment. Inside coated with Gaina improves environmental qualities such as warmth in winter.

Far-infrared is an electromagnetic wave. It is not affected by the flow of air. Even in the hot summer months the temperature of the outside coat of Gaina won't rise much, so the inside coat won't raise room temperatures either, unless the heat source is in the room. Far-infrared is invisible radiant energy that warms our bodies, not the air.

Gaina has the combination of radiation, low thermal conductivity and low stored heat capacity which controls temperatures effectively. Coming up, Gaina has even more benefits beyond the few already stated above.

2. What is the R-value of Gaina?

R-value is the measure for resistance of heat transfer. It's one of the thermal insulation evaluations used to protect consumers and provide information. There are several ways to measure the thermal insulation performance, such as U-value (conductivity, opposite of R-value), K-value (thermal resistance of the material such as wall, ceiling or floor) and so forth.

R-value testing is done within controlled conditions, trapped, stagnant air (70 °F or 21 °C) with no air movement. Heat moves from higher to lower temperatures, just like heat from outside in summer and heat escape from inside during winter. It's the measurement of temperature from one side of an insulated surface to the other side. Higher R-value products take longer to absorb heat. It depends on the thickness of the product, and can often be measured by the inch.

Gaina is the thin insulating material that is only 0.0118 of an inch thick. Still we can measure the R-value of Gaina, but it is difficult to obtain a comparative insulating performance measurement.

Gaina has totally different components than general insulation.

REFRACTION

Gaina provides a thermal barrier with the prism effect within the spheres of the ceramic beads. Through reflection and refraction of infrared radiation, heat penetration is reduced.

Gaina also provides a radiant barrier from the material blended with the ceramic beads. This substance reflects visible and near-infrared light.
A radiant barrier doesn't absorb heat, so there is no measurable R-value.

REFLECTION

Because Gaina has a complex insulating process, the difficulty is in measuring its performance via conventional methods such as R-value. So, R-value information becomes meaningless.

These are just two insulating qualities of Gaina. More information will be in later articles.

1. Gaina (Gāina) means GREAT!

Gaina is a light, thin thermal insulation material. Based on the aerospace technology to improves our environment, during any season, day or night, to provide a comfortable living.

Gaina can be painted in the same way as water-based paint. It contains a mass of very small special ceramic beads in the coating film. Ceramic has a feature that is strongly resistant to ultraviolet radiation and is very resistant to deterioration. Because of this feature, Gaina has a durability two or three times compared to general paint.

Unlike ordinary paint, this special ceramic product has a variety of benefits. A surface coated with Gaina reflects the infrared rays at a high level and prevents the adverse effects of sunlight. Furthermore, there is continued relief from the force of far-infrared radiation, because the accumulated heat from radiation that is not reflected away from the structure is hardly noticed on the coated surface.

Since less heat remains in the film it will adapt to the environmental temperature, whether it is hot or cold. This process makes Gaina very efficient.

There are more benefits to using Gaina. Gaina is able to improve air quality of the peripheral environment, and reduce noise levels with its multiple layers of ceramic beads.

The meaning of Gaina is, "amazing","great" or "big". It's a dialect of Izumo, Shimane Prefecture in Japan, Mr. Ishiko, who is president of Nisshin Sangyo Co., LTD (developers of Gaina), was born in that area. According to its name, Gaina is amazing insulation.
