My situation is this: I moved into a new apartment last year and my office is the only room that isn't insulated, which is annoying. My daughter's room and her playroom are both insulated as expected. My office door has to be closed when I'm not in there.
Currently, I am using a meager space heater, but I feel like things can be better. Are there insulation boards I can nail to the walls and ceiling? Or should I try and get my landlord to do it?
