In the apartment I am in, there is baseboard heater located under the balcony door
During the winter cold air come through the wall, and from gaps or crack between the wall and the floor
Usually during winder, around windows, I just put duct tape around windows and in any area that leaks cold air (gaps between the wall and floor)
I am thinking to unscrew the heater, put some tape on the drywall for insulation (reduce or block the cold air flow)
What type of tape should I use, that would be effective and safe, should I use regular duct tape or is it better to use foil tape, or something else completely
