What is the “Achilles Heel” of radiant barrier?
One most know one’s strengths and one’s weaknesses! Think about this. What makes a mirror not reflect well? Dirt! It is the same for radiant barrier so when dust collects on the upward-facing highly reflective surface of the radiant barrier, it then has a very low reflectivity and is now a very good absorber. Now only the downward-facing low emissivity surface is left to do the work. All of our patented RBS products have multiple layers which insure dust accumulation on the top layer does not degrade the performance…forever.
