I am looking at building a small forge on ' skids ' - zoning issues - will probably never move but . . .
My question is about whether or not insulating it is practical or not. I live in central Saskatchewan (Canada) and our winters are cold -40 is not unusual, snow etc. This will be a hobby thing for now, but I'm mostly retired, and who knows? This will likely be used mostly in winter, as my wife and I are gardeners, and have lots to do in the growing season.
The building plans are fluid now, but will probably be in the 10-12' X 16' range, with overhang for outside storage, etc.
I am looking at using a small propane forge, but mostly charcoal (30 acres to work on, more-or-less free wood, + steel drums. . .)
Any thoughts on insulation, ventilation, ceiling height, etc., would be appreciated.
