Another effective solution is to install a door sweep. A door sweep is a long strip of material that attaches to the bottom of the door and hangs down to cover the gap. Available in various materials, such as rubber, vinyl, or even metal, door sweeps are designed to establish a barrier against drafts. Choose a sweep that brushes against the floor lightly; this ensures it blocks the cold air without hindering the door's movement. Installation is usually a simple process, requiring just screws to secure it to the door.
