Heat Insulation
Other
Type
Conduction – limiting heat flow through solid materials
Convection – trapping air or gas so heat cannot easily circulate
Radiation – reflecting heat away from a surface
Common heat-insulating materials include fiberglass, foam, mineral wool, polystyrene, cork, and reflective foil. These materials usually contain tiny air pockets, since air is a poor conductor of heat.
Heat insulation is widely used in buildings, refrigerators, hot water tanks, ovens, industrial equipment, and clothing. Good insulation helps reduce energy consumption, lower costs, protect equipment, and maintain stable temperatures.
