So I wanted to offer a different idea than glue for edges... I was a at a building conference, for a "best practices in Passive House 2.0 construction" seminar, and they were using a lot of foam board insulation on the outside of conventionally framed stick building. Their (this engineering firm who consulted on and observed several different passive house builds) preferred method to get the super high R values was to sheet the outside wall of the stick frame (2x6 generally) with 3/4 plywood, and then attach 4-12" worth of hard foam board insulation (thickness per climate requirements). they attached the board with vertical lathe and long screws - so the foam was laid out horizontally, x number of vertical strips of 1x3 or something like laid on top and screwed through to the plywood. the rigidness of the foam plus 12-16" spacing of screws made the tension triangulation strong enough that any kind of siding up to and including stucco could be hung on top of the lathe with no functional sag (measured in the .0Xmm angular deflection). corners were held by a cap long enough to get screwed into the plywood.
this creates a compression fit of all the corners, no need to deal with glues, and fast screw bonds. It requires more wood material, and then some precision corner cutting of it, but gives you a significantly stronger building. lmk if this is clear enough of a description.
