I saw a video demo of this Aarmourtherm Foam tonight at my in-laws on the "Caught On Camera" show. Guy makes an edible super insulating foam. He scoops some up and then takes a cutting torch to the goop in his hand. Then after cooking the foam he eats a tablespoon of the stuff.
I am just wondering if the RMH guru's have heard of it?
I was also thinking about the shipable cores and how this stuff might make this a more weight efficient reality.
Erik; Interesting stuff... at their website ,they mention that their test piece made entirely of their product was "rather fragile" reminds me of a cast core with fireclay and perlite... works great as an insulator but is very fragile when adding wood. If its not to expensive to get a fair amount, then using it to surround a brick core as an insulator might be worth a try. The possible commercial uses of this as a biodegradable insulator are staggering... if it gets main stream acceptance. Thanks for sharing.
