Cob Ener-Grid revisited

[EREC - Duncan, Cameron]

Here is a copy of information I provided another inquirer about Ener-Grid   
in July that may be of use to you.
.................................................................
     If you investigate the Rastra/Ener-Grid product, you will find the   
reputed R-35.5 that the company projects was performed by Braun Intertec.   
This reputable certified lab repeated the tests before releasing the   
report to confirm the numbers. A subsequent test by the Construction   
Technology Laboratory found the assembly to yield only an overall R-value   
of about R-6 to R-8 (R-1.41 per inch).
     You may also wish to perform a little analysis of a sample and let   
me know how it performs. Place a sample in an ant pile, near a termite   
infested element, etc. and check it over time to determine if insects are   
able to infest it with passageways. I've read they cannot, but I believe   
that written material was generated by the manufacturer.
     Should you wish to contact the company:
          Ener-Grid Building Systems, Inc.
          6847 South Rainbow Road
          Buckeye, AZ 85326
          (602) 386-3298
