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.
