So ahh yes , You are correct. My apology's Jean Paul, just an old man rambling...
Thanks Thomas, Gerry!
My current plan for the bench is:
* Rear brick "retaining" wall providing 4" airgap along the first run (right out of the manifold and the final duct run before the chimney)
* Dry brick and fieldstone rubble directly on (quite dry) concrete
* Cob and fieldstone on top of that
It sounds like I should have thermal cob (clay and sand) around all of the ductwork to form the backup ductwork when the metal ductwork fails. This should be "filler" for most of the bench. I should have structural cob (clay, sand, straw) below my metal ductwork (on top of my dry rubble layer) and on top (around 2" thick).
Does that sound right? You asked about encasing the bench in another material. I have the brickwork on one side. The other side will be up against sheetrock. If I am using cob for the other sides, it seems like that should be a couple inches of structural cob (clay, sand, straw) as well?
