R-Values

What About R-Values?
R-Value is commonly used to indicate the insulation's effectiveness. However, R-Value is only a measure of thermal resistance (conductive heat transfer) and is not applicable to the other modes of heat transfer. It serves no purpose in rating a product's ability to reflect radiant heat energy. When properly installed, Reflectix® has a respectable R-Value, which effectively resists heat transfer through thermal conduction. The primary value of Reflectix® lies in its ability to act as a radiant energy barrier.
