How Does a Radiant Barrier Work?

Radiant barriers have high reflectivity values, allowing them to reflect 97% of the radiant heat that hits it. They also have super low emissivity values, which keep them from re-radiating that 3% of absorbed heat. This basically allows the radiant barrier to virtually stop all radiant heat transfer into and out of a home or building.

Because radiant heat is the most efficient type of heat transfer, blocking out radiant heat is one of the most effective ways of decreasing your monthly heating and cooling cost. In the summer, less radiant heat will enter your attic, making your AC system run more efficiently and in the winter, less heat will be lost through the attic, making your heater more efficient.

Radiant barriers are the most affordable, energy efficient retrofit installation that anyone can do to virtually any home or structure. We highly recommend Ra-flect Radiant Barriers, they are super strong, durable and very affordable.
