   We need more information to better help. What size is the closet and which wall is the studs missing? Can you not build a wall in front of the spray foam? Can you install 2x members horizontally from stud wall to stud wall, so you have something to anchor to? You could always cut out the foam where you need to install studs and install the stud wall that way, very labor intensive though. Sorry I couldn't be more help, but without more information, we are basically "shooting in the dark".

   @pkrivanec711 , thank you! it's a small space with an 8' ceiling and measures 2' deep and 5' across. The ccSpf is sprayed against CMU. I suppose I could cut out a little foam - enough to install a bottom and top plate of 2x on the flat, and then fill that in with vertical studs... do you think I can glue onto the foam and screw through the foam into the CMU? Or do I need to remove all the foam down to the CMU to anchor with tapcons... after I finish banging my head against the wall ; ) thank you.

   Avoid cutting the foam, very messing and time consuming for little payoff. I like Mike42's approach with the thin metal stud. If you want to stick with wood, then I suggest 2x2's or 2x3's for the framing to help reduce the overall thickness of the wall. If this is just a storage space, then and hidden behind double doors, then the fire-resistant paint (Mike42 suggested) would be the easiest solution.

   Couple ways to go. (assuming you want to make a closet in front of the electric panels)

   You can frame in front of the foam.. consider metal framing which is sold in inch and a half thickness to leave more room in your closet. you can tapcon the channel into the floor, and bring the top back to catch the bottom of your floor joists above. another building material to deal with, but who does not like that? You would have to buy a pound of fine thread drywall screws.

   I included a similar wall in my basement when I needed to move a wall to make room for my fridge after adding insulation to the outside wall. using the thinner metal studs left more room in the already tight utility room than using wood studs would have allowed.

   another thing to consider is just coating the spray foam with a fire resistant coating.

   I would resist trying to carve out much foam. You can trim a bit if you have to.

   I'd nail 4- 2 X 4's on the flat to the top and bottom plates, one in each corner and the others 1/3 of the way across.
