I’m not a fan of the log home, but it’s what I have. Yes I imagine I will have to build a “shell” around the house, but how. I posted this in the natural building forum on purpose. I know I can insulate with a vapor barrier then poly board, then siding. How can I do the same naturally. I suppose letting y’all know what materials are available could help. We have plenty of cedar that can be cut, our soil is a lot of sand on top of thick clay. Straw is not available at a reasonable cost in the area, but maybe there’s an alternative? My thoughts so far on a natural method would be to essentially build a cob house around the existing log home but I think that would cause moisture issues between the log and cob.
