[papercreters] Panels- double wall- insulating them

I think Mike in Tx  was going to leave air between the PC slabs attached to posts 12" apart. 

Inventor Ken Kern was really big on doing the same but pouring sawdust between double walls. when densely packed it is virtually burn proof ( no air). he  did this with wood walls too.

Maybe MIke had pearlite or fine caliche  close by to get and shovel into the voids?

One other trick Kern did that I loved is to  wrap  heavy paper around a stove pipe, tape, and fill with sawdust to make 'logs', then he laid them horizontally between walls/studs.

 I tried this,  found it too much work, and just used heavy paper grocery bags with high 'burst' strength.  I filled them with the redwood sawdust we have,  kept them sorta squared  & flat up while filling, and  stapled shut, they stacked up nicely in between the studs. 

I also tried coating them with clay to keep rigid, and add fire protection.(  one could dip in clay bath, or spray/brush on clay-coating)  I also tested using  those  cardboard Priority mail*  boxes 3.5" thick,16x12... I think, as stackable  blocks, pouring a wet mix of slurry in and around stacked boxes gives an insulation layer that stays put.

 Sean Sands also filled canvas sacks, placed between 2x4s  on the ground for  keeping squared, tamped them flat  let dry and peeled off the  sacks to re use.

* I only used the used ones I had, using new boxes could result in big fines for theft of postal materials, but there are other boxes of similar shape.  the local health food store has a huge bin of  their delivery boxes in all sizes you can take free.
