Radiant Barrier
Radiant barriers or reflective barriers inhibit heat transfer by thermal radiation. Thermal energy may also be transferred via conduction or convection, however, and not all radiant barriers do not necessarily protect against heat transfer via conduction or convection unless they are multiple layers of material "sandwiching" a traditional insulating foam product.

Famous quotes containing the words radiant and/or barrier:
“No
Praise that the spring time is all
Gabriel and radiant shrubbery as the morning grows joyful”

“Clearly, some time ago makers and consumers of American junk food passed jointly through some kind of sensibility barrier in the endless quest for new taste sensations. Now they are a little like those desperate junkies who have tried every known drug and are finally reduced to mainlining toilet bowl cleanser in an effort to get still higher.”
—Bill Bryson (b. 1951)
