The approaches that I have heard discussed:

   Strawbale wrapping the exterior cob walls and which are then plastered.

   Plastered Light-Clay panels wrapping the cob walls.

   Conventional insulation materials (blue board, etc.) wrapping the
   exterior cob walls

   Thicker cob walls with an interior gap that can be packed with an
   insulating material such as: wood chips, straw, dried grasses, foam
   peanuts or other insulative "waste" materials that might otherwise end
   up in a landfill.  For thicker insulation, this approach could also be
   used with two independent walls, a normal thickness inner cob wall and
   a separate thinner outer wall made using cob, wattle & daub, or some
   other system, the gap between the walls is filled the same as above.
