For the benefit of our non-SIU Murrican listmembers, the above translates  
to a thermal resistivity of R-1.9
per inch (in imperial units of ft^2*hr*degF/Btu*inch), which is a bit more  
flattering for SB than the value that the Californians have promoted as a  
result of their "certified" testing.

So Peter, I'm wondering if you could share with us, a bit about the  
testing set-up and procedure that was used in the UK testing program (or  
provide a link to a site that describes it) ?
