[Cob] Insulation Idea

[Charity Davis-Custer]

Hello Cobbers,

I'm new to the list and I've been reading about cob
for a few years (I've also read three years of the
archives....I will finish the rest soon).  I'm gearing
up to design and build my first cob structure.  I'm
looking to build a shed/partial greenhouse/winter
bunny house.  Space is a major issue as I'm building
in our tiny suburban backyard which is mostly garden
space.  I'm concerned about the lack of insulation
value in cob and I was considering wrapping the
exterior of the walls in a 6 inch layer of papercrete
(Charmaine Taylor's lime recipe) and then coating that
with a lime plaster.  I'm mainly concerned about the
north and west walls.  The south and east walls are
sun faced and will contain the windows.  I would
rather not use strawbale because of the added
thickness....I just don't have the space.  I will be
using a solar closet design and just plain old solar
gain but I would like to keep the building above
freezing in the winter.  Has anyone tried papercrete
for insulation?  Any suggestions?  Is this a
hair-brained idea fired from an inexperienced
designer-----> I'm rather well known for these ;)

Thanks for your time and the wonderful reference
you've created in the archives.

Keep on cobbin'
