Some how I don't think that a wall with 12 inches of fiberglass between 
some sheetrock would act equivialently as a 6 ft, 4 inch wall. My 
feeling is that if I lit a wood burning stove in each of these 
structures (the fiberglass, and the thick earth walls) the earth 
stucture would still take longer to heat up than the fiberglass walls, 
but would stay warm longer once it finally heated up. Thus mass is mass 
and has certain properties, and resistance to heat exchange is another 
property. Both exist no matter to what degree but they are not the 
same.
