The measurement of how fast heat loads or is absorbed and then the speed at which it transfers through the material is called the “R” value. This resistance factor slows but does not prevent the heat load and transfer. This is why these materials “must have more thickness” to provide any benefit.
Super Therm® does not absorb solar heat and does not require thickness — effectively eliminating a measurement of (R) value.
Super Therm® has four (4) ceramic compounds. Three of these compounds match the wave size of each of the solar radiation waves to block the heat load. The fourth ceramic has such low density that the heat cannot load into the surface of Super Therm® and therefore cannot be absorbed and transferred.
This is why the surface of Super Therm® is not likely to be more than 2-10 degrees F over ambient air temperature in any climate. If heat load is blocked, there is no heat to be absorbed and transferred even when the surface becomes dirty.
Field documentation shows no change in the performance of Super Therm® after 10 years, and only an 8% drop in blocking heat load after 15 years.
