[Cob] Insulative values

[Damon Howell]

Sky, I believe someone has went outside the boundaries of the subject  
matter at hand? I do agree that most of North America is frigid in  
the winter and homes should be built accordingly. That's why building  
codes vary throughout the country. BUT, I have read about 100% cob  
homes being quite comfortable year round in Canada. You're wanting  
cob to be something it's not. I've read that if the diurnal  
temperatures fluctuate close to 20 degrees then cob is a satisfactory  
material. The thicker the walls the longer it will take to heat and  
cool. You have to design appropriately, which is something Americans  
stopped doing when energy costs dropped. If you are sold on the  
insulation factor means everything and thermal mass means nothing  
scenario (which it sounds like you are) then I do not see room for  
cob in your life.
