Details
Radiant barriers (also known as reflective insulation) are a type of thermal (heat) insulations that inhibits 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 the heat source) or convection (perforated).
PRODUCT SUMMARY
There are many definitions of thermal/heat insulation and it is commonly misinterpreted as “Bulk/Mass/Batt Insulation”, which is actually used to resist conduction heat transfer with certain R-values.
