This solution R-12 batts between 2x4 studs with R-7.5 exterior insulation sheathing is very safe against air leakage condensation for this Toronto example. If R-30 were the target 0.37*30= R-11 of exterior sheathing and R-19 stud space insulation would be one solution.
Best way to insulate between studs with rigid foam
4) Would I gain a lot from using those rabbeted foam products that cover the studs with some insulation material or just filling the space between the studs would be fine? between studs. with foam tight against outside of wall . 5) Anything else I should do or I'm ready to drywall? The foam acts as a vapor barrier as I understand.

Foam Board Insulation - Insulation - The Seven Trust
The panels provide a continuous energy-efficient surface. This eliminates thermal bridging which is the energy lost through wall studs. The studs conduct more heat than the insulation between them. Insulating boards are just one of the many types of foam insulation. Consider using spray foam insulation as well to seal smaller cracks and gaps.
Is rigid foam and fiberglass batt between studs a good Idea
Batts in stud bays first then 1" foam panels to the inside of the room then drywall. Would having the ridged foam between the drywall and the fiberglass bats prevent moisture from migrating into and condensing in the walls? Perhaps adding a foam strip on the studs to create an air gap between the foam board and the back of the drywall.

What is the best rigid insulation for the exterior of walls
As for materials there is no need to switch materials at all. EPS rigid foam insulation becomes a vapour barrier at about 2 inches thick and that is fine to put directly against the cold foundation wall. The most important thing in a basement is not to sandwich wood studs between a concrete wall and a poly vapour barrier.
Exterior Foam Insulation: Best Practices
- 2’ x 6’ advanced framing with 1.5-inch closed-cell spray polyurethane foam in each stud bay - 3 inches of cellulose insulation covered by 0.5-inch gypsum with latex paint finish - Diagonal metal strapping on the exterior - 1.5-inch foil-faced polyisocyanurate board insulation and exterior vertical wood strapping for cladding attachment.

wall studs (optionally with batt or cellulose insulation in between) exterior sheathing; rigid foam; wooden strapping for attaching siding screwed to studs through foam. This provides support for the siding and also allows air circulation behind the siding so any moisture that gets behind the siding can dry out. siding panels nailed to strapping
2005-11-16 Guide to Insulation Sheathing
closed cell foam (slow water vapor and air transmission through the cell walls) the gaps between the cells will still allow for moisture to pass through the matrix. With increased density these spaces are reduced and the ability of the foam to allow water transmission is reduced.
Rigid Foam Insulation 101: (Important Installation Tips)
Secondly – and this is the best way – you can install a drywall to frame the wall before applying foam board insulation. Use 2×2-inch lumber for the studs and 2×3-inch lumber for the top and bottom plates.
Builder Innovates on the Double-Stud Thick Wall for More
The decision to use the double-stud wall method for the ProHOME came down to a matter of cost. When they looked at the price of materials and labor Paul and Tim found that an R-40 2×6 wall insulated with closed-cell spray foam in the cavities and 2 in. of rigid foam on the exterior would be 14% more expensive than their R-45 double-stud wall.
insulation - Insulating a 2x4 wall with exterior rigid foam
Your foam is fine and is a vapor barrier so don't put another one in there! Your plan to use 4" of closed cell rigid foam as continuous exterior insulation is sound and will get your R-20 or thereabouts without any insulation in the stud cavities so adding rockwool to the stud cavities will get you well above your R-20 target.
Using rigid foam insulation to acheive R-19 in true 2x4
I am in the process of completely remodeling the interior of my 1896 Minnesota home. I will be gutting down to studs. Minnesota requires R-19 in exterior walls. I would rather not furr out my studs to 2x6. Can I (according to code) acheive R-19 by stacking two 2 inch R-10 panels in the

Closed-Cell Foam Between Studs Is a Waste - Fine Homebuilding
For example if a 2×4 wall has 3 in. of closed-cell foam insulation the R-value of the studs is based on a stud depth of 3 in. not 3-1⁄2 in. (because the exposed portions of the studs are basically “indoors” and not part of the insulated wall assembly).
