Basement framing, how do I tie new walls to existing insulated walls?

I am planning to finish my basement. I have a walkout. When framing my walls, how do I tie them in with my insulated exterior framed wall that is the walkout part? For interior I normally just do the 3 stud thing, but with this being exterior, how do I maintain the insulation and vapor barrier? I live in Minnesota.

Partition framing typically has 2 studs (one on either side of the new wall with one turned sideways between them, flush to the inside, with insulation between it and the exterior sheathing. The flat one provides a solid nailing surface for the partition wall framing.

You could also simply put a 2x6 sideways for your partition to butt up to... but you'd only have an inch on either side for drywall backing.... or only 1/2" if you rock the wrong wall first.

Not sure if that answers your question or not?

Thanks xsleeper! It Does make sense. I normally do the two on either side with one Sidways in between but didn't know how that worked with insulation. I like the idea of just the one 2x6 sideways, in regard to drywall nailing surface, would a 2x8 sideways be better?

You could, you'd have more surface area. Another way to do it if your partition falls between 2 preexisting studs, is to put horizontal blocking in, 16" on center as measured from the floor. That also gives both the partition and drywall a good nailing surface.

Thanks! I may need to do the ladder type, because after measuring, the wall will land on an existing wall stud, so I will have a gap on both sides I need to do something with drywall for. Thanks again for your help!
