Since you are in the great white north, you might want to build a

solid, insulated north wall.



I might suggest a close look at double wall polycarb panels
considering the great white north location, bwdik. I can highly
recomend the polycarb panels.

Actually I was planning on using my 30x40' pole barn as a north
wall. So that is covered. Not insulated, but I may add some thermal
mass to it. I'd just as soon use triple wall as anything else, but I
may go with inflated poly. Somebody told me that inflated poly has an
R-value better than the walls of most houses up here. My main concern
is heat. Has anybody used a hot water system?
