Hello!
I see that this topic has been discussed before, but I still want tips and thoughts. I've started tearing down this wall and plugged the pipes that went to the radiator that was there. I think I need to remove a part of the floor to access and remove the rest of the studs at the bottom. There are many questions and the budget is tight. I’m going to build a new wall there now. My thought is metal studs with some type of particle board and drywall on without insulation between the studs. Leave a gap at the top and bottom with ventilated moldings/baseboards. I have also read about ceiling/hat profiles to avoid ceiling and floor tracks. Another idea I've had is to build a new wall outside of all that and just enclose everything. Help!?
