Slip-straw is loose straw coated in a clay slip. You would then build
forms on the inside between studs and fill the gap with the slip-straw,
tamping it down as you go. You can finish it with a mud plaster. You
could also use cob where you wanted a more organic aesthetic. <br>

<font face="arial" size=2 color="#0000FF">I have worked with this method
and if you go this route make sure you get it ever so lightly coated so
that you can gain a higher Rvalue as normal straw clay won't give you
more that an R1 per inch and you don't want to go over 12". I still
find strawbale to much faster and easier and better insulation value. I
prefer to think of straw clay for interior walls.  <br>

<dd>I'm considering converting my barn to a home using cob walls on the
interior of the existing exterior barn walls.  Is this a stupid
idea?
<dd>The barn is somewhat old, but the structural beams appear to be in
good shape.  Would there be a problem with placing the cob right
next to the wood?
<dd>Maybe cob is not the way to go, I just want to use natural
materials.  Some other method may be more insulative, as well.
<dd>I would appreciate any ideas.

<dd>Chris,
<dd>Not to discourage you from cob, but you might consider slip-straw if
you already have existing walls. I am planning to do this to an existing
barn. Slip-straw is loose straw coated in a clay slip. You would then
build forms on the inside between studs and fill the gap with the
slip-straw, tamping it down as you go. You can finish it with a mud
plaster. You could also use cob where you wanted a more organic
aesthetic.<br>
