Radiant barriers (also known as Reflective Insulation) is one of the Thermal (Heat) Insulations to inhibit heat transfer by thermal radiation. Thermal energy may also be transferred via conduction or convection, however, and radiant barriers do not necessarily protect against heat transfer via conduction (without airspace facing to heat source) or...

Radiant barriers are installed in homes – most commonly in attics – to reduce summer heat gain and winter heat loss, which helps lower heating and cooling costs. The barriers consist of a highly reflective material that reflects radiant heat rather than absorbing it. They don't, however,...
