Planning to build an interior door between a closet (which currently has two entrances) and the living room. I have put up the framing and am about to plaster, but forgot to buy insulation. It feels unnecessary to go and buy a whole roll for it...do I have to insulate?
No, interior walls do not need to be insulated, only to reduce potential noise.
Alright, thanks. I'll ignore it then. Not worried about noise since it's a wardrobe.
