Radiant Barriers and Reflective Insulation

Shiny materials control radiant heat flow, but there is a great deal of misinformation about these systems. How Radiant Barriers Keep Attics Cooler In a hot climate with an unheated attic and the radiant barrier at the rafters, it's best if the shiny surface is facing down (into the attic). Its low emissivity means that it doesn't radiate heat into the attic easily—and since it's facing down, dust won't compromise its performance. Standard insulation—such as batts, boardstock, and spray foam—functions primarily by slowing down two out of the three modes of heat transfer: conduction and convection . Radiant barriers and reflective insulation function by reducing the third type: radiation . This can work, but there is a great deal of misinformation about these systems.
