air sealing this ?


ok, good. now, here is what i am thinking. 2" fb cut to nearly fit the cavity. then i spray foam all largish voids in the sheathing(there are only a few). spray foam around the parameter of the cavity where the framing meets the T&G sheathing. then press the FB into the cavity. in doing this, the sf will mush out and seal all around the fb to the studs. then i would double stud(thermal break) the framing and add insulation (after running the electrical). calk the studs/plates/electrical boxs and holes for the wires and install drywall.

good plan ? if not, please modify it.

Nothing about that thermally uncouples the framing.

That has to be done from the outside surface.

That framing is still going to be cold but if you seal up all the interior drywall, you should be fine.

Bulk air movement is the killer when it comes to condensation. Almost none comes via diffusion.

really ? i thought that if the outside framing is separated (at least in the middle) from the inside framing. cold would not transfer nearly as easy as just regular framing. as said here, pg27

so the end R-value would be higher, i am thinking.

let me put that a different way :
the sheathing is separated from the drywall.
there would be a lot less thermal bridging.

but, in the end = would it be worth the effort ?

That will help with the thermal transfer to the interior side of the home but not with any of the potential condensation issues inside the wall.

That is what I was referring to. By thermally uncoupling the interior side, you are potentially making the issue more severe because the framing will stay that much colder.

A quick and easy way to seal might be Owens Corning. It's a two step air insulation system at a fraction of the cost of some of the others. It looks like something that could definitely help remedy the situation, but ----------- and see what you think.

There is a bunch of suspicious OC postings lately under different names.

Part of OC market capture strategy?

ok, fella's. i have 1 window mostly/kinda in.

my T&G sheathing. there is no house wrap over it. it has a mortar looking stuff to fill the slots. the slots, they were cut into the T&G. idk why.
and then the asphalt siding.

so, how does this effect my air sealing ? right now the plan is 1" foam board,
and 3 1/2" roxul. with 1" wood added to the studs. and, hopefully kinda soon, but idk when really. i am going with xpf under the new siding.
