For those of us interested in alternative building, good insulation, good air quality and low power bills are of peak importance. And if we're going to put so much effort into figuring out how to use our alternative building materials, we want something economical and cozy when we're done.

Wikipedia on R-value http://en.wikipedia.org/wiki/R-value_(insulation)
Reliant Energy's version http://www.reliant.com/en_US/Page/Generic/Public/esc_oma_insulation_primer_bus_gen.jsp (While high R-values sound attractive, the real effect of insulation—the U-value—diminishes with each additional inch of insulation. For example, an insulated 2 x 4 wall has an R-value of 13 and a U-value of .077. Upgrading to a 2 x 6 wall adds 5 points of R-value (18-13) but only drops the U-value by .022 (.077-.055). Adding another 5 points of R-value would lower U-value even less—by only .011.)
I'm gonna leave it there.

I was looking through my files trying to find the maximum practically achievable insulation values and couldn't find the references I quoted though I can remember them. I have many hundreds of files on all kinds of insulations. It surprised me how many of these included discussions involving Elf Nori.
