2x3 exterior studs
Hi, I am in the process of doing some remodeling, and re-insulating my walls. Parts of the house use 2x3 wall studs, and I have some 3 1/2" Roxul insulation I want to use. Trying to think of the best way to extend the wall thickness out to the standard 3 1/2" width. Would it be better to sister the 2x3s with 2x4s and attach the drywall to the 2x4s, or to find some 1x2s and attack them to the end of the 2x3s? I am leaning toward the sistering 2x4s, because I am not sure about the drywall screws going into the 1x2s...or is there better way to do this? Thanks.

I would either add a 1x2 or rip some plywood or a board to the right thickness and staple it to the faces of the 2x3 studs with a sheathing stapler to make them 3 1/2" wide.
Sistering all those studs reduces the insulation in your wall too much and if there is electrical in the wall it would be a mess.

In your area I'd guess R-19 would be code in the walls, not R-13 to meet modern building codes.
While that walls open here's your chance to add some more insulation by building it out more.
Sistering is not the answer.
