Log home insulation retrofit
I'm exploring strategies for insulating an existing log home. External insulation makes the most sense to me. What are thoughts and comments about this assembly: 2x4 stud wall with closed cell spray foam covered with r-sheathing? The sheathing is needed because I think the budget will require vinyl siding. I'm not sure about air barrier and a drainage plane tho. Any comments or suggestions would be appreciated. Also thought about a nail-base sip, but I'm concerned about how to attach it, and possible thermal bridging if long lag screws were used....
