Does Cerama-Tech have an R-Value?

R-Value is a measure of insulation effectiveness (a measurement of resistance to heat flow by conduction and convection for a given thickness). Cerama-Tech works like a Radiant Barrier, and is considered a Radiant Control Coating (RCC) according to ASTM. Because RCC’s reflect thermal energy and their effectiveness is based on reflectivity, there is no fixed R-Value for the material rather, it varies according to the temperature difference from the bottom to the top, or from the outside to the inside.
