Heat Shield: Heat Transfers Three Way

Conductive Heat
The direct flow through a solid object from hot to cold.

Convective Heat
Convected heat flow is mostly upward somewhat sideways. Heat flow is never downward when air is warmed. Warm air expands, becomes less dense and rises.

Radiant Heat
Radiant heat is the flow of invisible infra-red rays emitting from the surface of an object, because of heat within it. All objects give off radiant heat, called radiation.

Quality Heat Shield Insulation consists of two sheets
of 99.5% pure industrial grade aluminum laminated to 3/8" fiber tech padding, to achieve the highest reflection of radiant heat and sound deadening. It conforms to Federal Motor Vehicles Safety Standard (FMVSS) 302 flammability on interior materials as specified in the code of regulations, Title F49, transportation Section 571.302. U.S. Coast Guard approved for interior finish. This product passes UL-723 and ASTM-E-84.
