Do the wood chips need to be dried? Won't high moisture cause molds which can be just as dangerous ? I believe we can come up with something cheaper, safer , and better. Industries that sell insulation probably aggressively campain to suppress these ideas. I recently heard of adding water to blown in cellulose insul. and it stuck like paper machete. What if rag wool was formulated with a waterbase glue and sprayed on wattle and daub framework and plastered over to seal. I also believe out-gasing is responsible for many respitory and other health problems. Much of todays line of thinking seems geared toward making the insut. materials un-palatable to orginisms harmfull to us but they are usually also very toxic to us. Maybe materials should incorperate materials that work against the growth of harmfull pathogens , such as garlic or marigold. It would ward of werewolfs too , ha ha.
