Materials That Reduce Heat Transfer | Hunker
Materials That Reduce Heat Transfer | Hunker

Clothing reduces heat transfer because material is not a good conductor of heat. Because your body tends to be hotter than the outside world, putting cotton, wool and man-made fibers between your skin and the air keeps your own body heat in. The clothing prevents your heat from escaping into the air.
