When a high reflective, low emissive material like Sigma's 3100 Series is facing into an open and vented space like an attic, it is called a radiant barrier. A radiant barrier works by reflecting 95% of the infrared or radiant heat that strikes it, and by not emitting over 5% of infrared or radiant heat through it.

The Stefan–Boltzmann law describes the power radiated from a black body in terms of its temperature. Specifically, the Stefan–Boltzmann law states that the total energy radiated per unit surface area of a black body across all wavelengths per unit time (also known as the black-body radiant emittance) is directly proportional to the fourth power of the black body's thermodynamic temperature
