Cold climate wall options
Getting ready to do first home build in zone 6a mid 2021 so researching as much as possible to prepare. GBA and other fine sources as data base but not sure as to which direction to go. Double stud wall 2×4 filled with cellulose and continuous external insultion, traditional 2×4 with external insulation exceeding code and then cavity fill, or 2×6 Advanced framing plus external insulation and cavity fill. Was leaning toward 2, 1 inch EPS layers on external with a rain screen. and cellulose internally. Like Rockwool but the cost… this will be a pretty good house on a budget cause I am a tight wad. Any direction will be appreciated. By the way this source is a wealth of info and geek out reading, watching, linking to all the material. Keep on doing It!
