Aluminum Foil Backed Woven Fabric Reflective Radiant Barrier

Radiant Barrier is a reflective insulation usually made of aluminum. It is installed in attics and inside buildings, requiring a small airspace to be effective. Once installed properly, it blocks up to 97% of radiant heat transfer.

Unlike traditional insulation that absorbs heat, Radiant Barrier reflects heat. It stops radiant heat loss by reflecting heat rays back to their source, keeping spaces cool in summer and warm in winter at a reduced cost.

No, Radiant Barrier does not usually have a measured R-Value. Since it reflects heat back to its source rather than absorbing it, R-Value is not an accurate measurement of the energy savings it provides.

It is effective in both summer and winter. In winter, it prevents heat from radiating out to the cold outdoors. In summer, it reflects the majority of heat from the sun back to its source, making air conditioning more effective.

Yes, experts at institutions like the Florida Solar Energy Center and Oak Ridge Laboratories have confirmed its effectiveness. Analysis shows it prevents radiant heat transfer with up to 97% effectiveness, compared to only 10% for ordinary materials.
