Reply to comment by Traveling_Carpenter in How to insulate 24" stud spacing with 2x3 framing? by Blackking203

It's a wall in a basement laundry room. The wall is a concrete foundation wall that has some 2x3 framing on it already

Personally, I’d take the framing (really furring) out first. Make sure there are no leaks in the wall or walls, and if there are you have to fix those before you think about insulating. For insulation, rigid foam right against the foundation to cut off thermal bridging. Foam thickness depends on climate zone and insulation type (eps, xps, polyiso, phenolic). Then reinstall the furring and fasten your drywall to that.

So the studs are nailed to the concrete wall. What do you recommend to take them out?

A hammer and a big flat bar or something similar should work. Even a big flat shovel or floor scraper - whatever you have that you can hammer into the joint between the wall and the stud. Start at an end - top or bottom - and work to the other end. If the nails pull through the studs, no big deal. You can use vise grip pliers to kind of twist the nails back and forth until they loosen, or if you don’t have those, just tap the exposed nail back and forth with a hammer until they fall out or break off.
