How Radiant Barrier Works: Heat Gain/ Loss in Buildings

The Physics of Foil There are three modes of heat transfer: conduction, convection, and radiation (infrared). Of the three, radiation is the primary mode; conduction and convection are secondary and come into play only as matter interrupts or interferes with radiant heat transfer. As matter absorbs radiant energy, it is heated and a gradient temperature […]
