Radiant barriers are seldom the cost effective option, especially in the north.

This is the current perversion of a bit of science into over enthusiastic marketing. Radiant barriers can, when properly installed, reduce radiant transfer of energy. The question is whether this is the best use of your home improvement budget. In my opinion the answer is almost always a resounding NO!

Before we go any further download this information from the Oak Ridge National Laboratory (ORNL) http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=5&cad=rja&ved=0CF0QFjAE&url=http%3A%2F%2Fwww.ornl.gov%2Fsci%2Fees%2Fetsd%2Fbtric%2FRadiantBarrier%2FRBFactSheet2010.pdf&ei=MIY3UdahKsSo0AGfnYAg&usg=AFQjCNHP3S7G_7P2KLEhesLTMuIOId31NA&bvm=bv.43287494,d.dmQ

This rather dull fact sheet lays out the case for and against the radiant barrier in different climates, with savings estimates for several starting points. In short it finds that even in warm climates radiant barriers are not always the cost effective solution. Cold weather climates really offer little opportunity for savings.

Have you ever been approached by a salesperson for this technology? What was your reaction to the pitch? Leave me a comment below.
