Cob cavity wall insulationEric Hart erichart at mtn.orgTue Mar 10 15:48:24 CST 1998
Here's an idea for adding some insulation to a cob cavity wall. Cordwood builders like Rob Roy use saw dust with a little bit of lime for preservation as insulation between the cordwood walls they build. This seems like a pretty low impact insulation material that would have better insulation properties than light clay. Rob Roy's Earthwood Building School has a web page at: http://www.interlog.com/~ewood Not too many technical details but a good introduction to cordwood masonry construction. Eric D.
