A draft stopper is a loose or slide-on tube that lies against the door bottom – no tools, good for renters, but it can move. A door sweep is fixed to the door face and moves with it – the long-term fix. A double-foam bottom gasket slides under the door and seals both faces. For exterior doors a fixed sweep or threshold seal is the reliable option.
Side-by-side

| Self-adhesive sweep | Silicone/TPE lip on the door face | Peel and stick | Interior doors |
| Screw-on sweep | Rubber or brush in a carrier | Screws | Exterior doors |
| Threshold / garage seal | Seal on the floor | Adhesive or screws | Garages, large gaps |

Quick questions
Do draft stoppers really save energy?
They stop cold air under the door, which is often the biggest single draught in a room. A fixed sweep does the same job more reliably.
Can a door sweep go on a carpeted floor?
Use a soft silicone or brush sweep set so it just touches the carpet; a stiff rubber lip will drag.
