A radiant barrier is a type of building material that reflects thermal radiation and reduces heat transfer. Because thermal energy is also transferred by conduction and convection, in addition to radiation, radiant barriers are often supplemented with thermal insulation that slows down heat transfer by conduction or convection.

: 738 allthingsaluminum〉202199ヂ According to thermodynamic principles, aluminum foils can absorb heat from any type of heat source. When an aluminum foil gets exposed to heat or flame, the foil gets directly heated. If you are using the foil over the top of an oven range, the oven heats the air around it. The phenomenon of convection occurs, and the heat gets
Physics Stack Exchange〉I understand that aluminum can partially reflect the sun and other heat radiation if placed on the outside of cooler bags. However, most types of cooler bags only actually have the foil on the inside and are non-reflective on the outside.
