[Public-List] Insulating the icebox - NASA's Areogel

[John Birch]

NASA's Areogel has been reported to be quite good and is non hydroscopic, 
non flammable R10.3 per inch.

Seems the best option now that Glacier Bay has gone out of custom vacuum 
panel production (those panels worked great and were R50 an inch, but if the 
panel leaked, then it was R10 - and leak sooner or later they would - they 
were very expensive)

Areogel is not cheap, but not ruinously expensive either. You get what you 
pay for, and the price has been falling.

And who said the Space Program doesn't have tangible benefits on Terra 
Firma, not I for sure.

4 inches of Areogel insulation = R41.2. Personally, if I were going to the 
trouble of doing an ice box teardown & buildup I'd go for 5" for R51.5.

Simply Google Areogel

Hope this is a help
