Cob: fibrous insulation tubes

[Taylor Publishing-DirtCheapBuilder]

Charmaine,

Regarding those packed-by-yourself insulation bags and boxes, do you 
feel they need any type of fireproofing or insectproofing? I also assume 
it is dry sawdust rather than damp or wet - boy, would that be a quiet area!

Patricia,

Yes dry sawdust...
Ken Kern put in some dry  hydrated lime, and mixed it up, so yes I'd at 
least so that, and I always recommend  coating the box with clay slip, 
so you add more fireproofing layers.  Waxed paper boxes, as in the US 
mail kind  or anykind have inks etc on them too, so preventing/  slowing 
burn rate is good.  but the sawdust does not offer enough oxygen to burn 
easily so it makes a good insulation.   casting blocks to infill is 
prolly the smartest thing to do.
