Cob: roof insulation

[Shawn Honeychurch]

HI All
Still working on our strawbale house design.
I read these postings regularly, but usually don't have much to add.
I've been reading up on roof insulation, though and had a question to post.
It is suggested that you have insulation with an R value of 35 in your
ceiling/attic/roof.
I would like to use a natural material such as straw-clay panels or layers
of cardboard or papercrete for insulation in our roof, but have no idea of
the R value
for such methods.  Anyone know how paper or straw-clay compare to pink
insulation?
I wonder how thick I'd need to make my straw-clay panels or papercrete,
or how thick to layer in cardboard.
Any thoughts would be much appreciated!
