Double stud walls – vapour retarders
Good day folks. I am in a cold climate (Halifax, NS, Canada) climate zone 5 or 6 I think???
I am constructing my house in the spring and will be using some variation of the DBL stud wall; either the Riversong DBL bearing wall, or constructing the house conventionally then stand up walls from the inside. I will be going for 10-12″ thick. My main question is about air leakage control, and vapour control. On the inside I am going to likely do ADA, and on the outside is it overkill to use adhesive on every stud and plate before I attach my 1/2″ PLY and then tape all the seams?
Has anyone here used both methods I mentioned above to frame? I really love the Riversong DBL bearing wall as it is a system that seems very stream lined, with how to insulate it etc… but it takes you that one step past unconventional framing which could cost me alot of time in the end.
The ease of the other method is nice, but it throws a wrench in the rim area for air sealing and insulating, as well as thermal bridging for the whole floor assembly and you have to net the well to blow the cellulose now.
I have framed and air sealed two passivehouse cert. homes in the past, so none of this is green to me. I will be doing most of the work myself from the foundation to the trim, and subbing out plumbing, elec, and mudding. Just looking for some pointers to prevent any head scratching!
