Understanding Cob - Great Pictures And How To

Categories: Building Methods



Cob alone has excellent thermal mass. But it is not the best at insulation, and eventually the heat or cold from one side will arrive at the other side. So in extreme climates pure cob should not be the only material you use. Strawbale and other lighter, non-conductive materials have more insulating value. Eco-Sense in Vancouver (Ann and Gord Baird) are mixing pumice into their cob. Their mix of 30% clay, 30% sand, 30% pumice and lots of straw is showing good test results. www.islandnet.com
