Rob, thank you for the tantalizing lead. There was the Solar Decathlon 
House from Germany that included vacuum panels in its ceiling. This is 
one of those things that look great for two weeks in Washington but like 
evacuated water heaters, once the vacuum is lost (think fallen tree limb 
or careless roofer) you've got the flat tire and no easy fix.

Glacierbay's claims seem much like those we see occasionally about the 
space-age crystal insulation that have R-90 per inch or some such. For 
those who haven't visited the site, these are moderate vacuum panels 
which are also filled with Aerogel. The aerogel is supposed to keep 
loses low if the panel is punctured so it seems to me that these might 
be described as a hybrid foam vacuum panel. "Moderate vacuum" means 
there is still significant gas to transfer heat from one wall to the 
opposite depending on the viscosity (?) of the proprietary gas 
contained, (argon or krypton?).  As such it is hard to imagine the 
claims of 50x the insulation value of  urethane foam. And I'm always 
suspicious of companies which only offer in-house testing lab results.
