I live in a northern climate and the 0.25 R-value of
cob is a great 
inhibiter.  We would like to buld with cob.  My older
son (15)really 
likes the cob concept and the ability to create
flowing structures.  
He has some great ides for his room.

However with an R-value of 0.25 a wall 25 inches thich
only has a R5 
insulation quality.  This is a far cry from the
minimum we need of 
R25 and the preferred of R40.

Some people have spoken of the construction trade only
considering R 
values and not thermal mass.  On hot days the thermal
mass is really 
great and will keep the interior cool.  In cool climes
the thermal 
mass will help contain needed warmth  However, here in
Winnipeg, 
Manitoba we have long, long periods of severe cold -30
  -40 C.  The 
thermal mass work get cold and become a heat sink and
be very 
costly.  Therefore it is necessary for us to create a
high R-value.


We have some ideas we will hope to test in practice
constructions: 
workshop, garage etc.  We do not wish to spend a lot
of time in 
experimentation so we would like to know if there are
practiced 
cobbists creating homes in severe winter climes.

Thanks
