One of my bedroom doors has gaps at the bottom and side. How can I close or seal these gaps. I would like to heat only this room and prevent loss of heat to other rooms.
The gap at the bottom is from 1/2 to 3/4 inch. The floor of the room has a carpet.
The gap on the side with the door knob is the largest.
Weather striping products and door sweeps seem to be for external doors.
