Radiant Barrier
Radiant Barrier is a multilayer, reflective type of insulation, available in rolls of various widths and lengths, that reflects radiant heat back to its source. Two outer layers of aluminum foil reflect up to 97% of radiant heat. Each layer of foil is bonded to a tough layer of polyethylene for strength. Two inner layers resist conductive heat flow, while a center layer reinforces it.
Radiant Barrier is a reflective material that reflects up to 97% of the radiant heat that strikes its surface back to the source. In the hot summer months, radiant barrier will reflect the sun’s rays. In the winter, it helps to eliminate ice dams. Radiant Barrier does not have a high R-Value on its own and should be used in conjunction with a good R-Value insulation.
How It Works
Radiant heat, the major source of heat flow, is energy in the form of infrared waves. It travels at the speed of light, even through a vacuum, and is either transmitted through, absorbed into, or reflected by any material it contacts. Air, water and glass, for example, transmit visible light in varying degrees. A white surface, such as snow, reflects it; a black surface absorbs it. Radiant barrier insulation reflects up to 97% of the radiant energy striking its surface. In other words, in the hot summer months, radiant barrier reflects the sun’s rays while retaining interior heat.
R-Value Information
Most insulation is measured by R-value, which is the thermal resistance of the product. Radiant Barrier is measured by emissivity. For a reflective insulation to be most effective, it must be installed with airspaces. The thermal value of the insulation system will vary depending on the size of the airspaces and the direction of heat flow. This is why with just radiant barrier, we can achieve several different R-Values. For more information regarding Radiant Barrier please visit: energy.gov
