The wall is stood up, set on the bottom plate and the top meets the ceiling marks. Shims make up any gaps and I shoot with long screws into the joists above. I put 2" foam in the back of the stud bays and use expanding foam around the edges to create a vapor barrier seal. I get an R30 wall that way. Any drawbacks you can see to this system? It's all above grade. Any vapor in the wall has a route to the outside around the unsealed sheets and through the block/hardiplank siding.

@dougdobbs As long as your 2'' foam board and expanding foam is approved for use by the building department, then it sounds ok to me. If ,god forbid, there is ever a fire inside your home you need to be sure the gasses from the foam does'nt kill you before the smoke and fire would. +++Bob

hi,

thank you for the video. i have a question. when do you apply the moisture barrier? is it before framing directly on the concrete wall or on top of the insulation? thanks.

@saboorstress Have installed barrier both ways and will never install vapor barrier on concrete walls ever again!(MOLD ISSUES!) If you choose to install a barrier at all(Not that I recommend doing so) I would use paper barrier on heated side of walls. I believe that allowing walls to breath and not installing one at all is best option if your local building code allows for barrier free application. +++Bob

Hey Bob, quick question for you.... If I put down a subfloor do I still need a PT base or would that be overkill ?

[HomeRemodelWorkshop]

@4x12 No need for treated unless it directly contacts concrete. +++Bob

@HomeRemodelWorkshop Yeah, I hear ya on the fumes. I am planning for hard wired smoke detectors throughout the building, with a couple battery backups for good measure. Where I live there is no inspection for any work done within the existing building, so I'm sort of on my own. That's why your advice means so much. Keep up the good work! :)

Bob, some feedback if you would? I've got a house with concrete block perimeter walls. I'm insulating on the inside with sheet foam, then a stud wall inside of that. I passed on the "fit each stud individually" method, it would drive me crazy. :) I've opted to lay down my marks and install a bottom plate, then build my wall to the height of the shortest gap between floor and ceiling.
