Martin is proper and is pretty cautious with how he states his conclusion about radiant barriers. I'll seek to be much more blunt. Given that just one cannot just equate radiant barrier to insulation R-price I'll utilize the term Strength which encompasses heat and radiation and use an arbitrary price For example the point. Appropriately setting up a radiant barrier will reduce Power transfer by some arbitrary price five, but for the same amount of cash 1 can buy insulation that could cut down energy transfer by 5Y (in which Y can be a amount > one). So The purpose Martin is earning is that if compelled to chose, why not devote the exact same amount of cash on something that will do an improved career? To conquer the useless horse…yes, great insulation (like foam or cellulose in an air sealed cavity) does an improved career than the usual radiant barrier.
