For a material to be considered as a radiant barrier, it must have a reflectance of 90% or more and an emission of 10% or less. This is according to the United State Department of Energy regarding classification of products for the purposes of measuring or providing incentives.
A radiant barrier uses foil like surfaces to reflect rays back to their source. The main properties on the surfaces of such barriers which enable them to reflect away heat:
The ideal radiant barrier products have reflectance of over 97% and emission levels of just about 3% which exceed the minimum classification by the US-DOE.
For proper functioning of the radiant barriers, the reflective side must be installed at an angle of ¾” and they must face the open air space. The following are some of the common areas where radiant barriers would be installed:
