Drafts come from two places: the gap along the sash or jamb, and the gap under the door, and they need different products. We pair a self-adhesive V-seal for narrow jamb gaps, a screw-on door sweep for the threshold, and a compressible EPDM foam tape for wide or uneven gaps, so you can seal the whole opening no matter its shape. Measure each gap first, because the thin profile that fits a tight window sash is not the one that fills a warped old door frame.
A self-adhesive folded-vinyl V-strip that seals narrow gaps along double-hung window sashes and door jambs. The V-hinge springs open to seal irregular gaps while letting it close, and it installs with no tools even in freezing temps. Weak points: the adhesive can lose grip over a few seasons on dusty or painted wood, and it only suits narrow gaps.
- Drafty windows
- Drafty doors
- Air sealing
Pros
- V-shaped hinge springs open to seal irregular gaps while still letting the window or door close
- Adhesive is formulated to bond even in sub-freezing temperatures for winter installs
- No tools or fasteners needed; you just peel, cut to length, and press into the jamb channel
Cons
- Self-adhesive can lose grip over a few seasons, especially on dusty or previously painted wood
- Only suits narrow gaps; wide or uneven jamb gaps need foam tape or a different profile
- Vinyl is not paintable and the white/bronze strip stays visible along the frame
A screw-on aluminum-and-vinyl door sweep that seals the under-door gap V-seal and foam tape cannot reach. Slotted holes let you adjust height for an uneven threshold, and the rigid aluminum carrier outlasts stick-on sweeps. The trade-offs: it needs drilling and screws, must be cut to width, and set too low it drags and wears the blade.
- Drafty doors
- Air sealing
- Blocking under door drafts
Pros
- Seals the under-door gap that V-seal and foam tape cannot reach, a top source of drafts
- Slotted screw holes let you adjust height for an even seal against an uneven threshold
- Rigid aluminum carrier is far more durable than stick-on foam or brush sweeps
Cons
- Requires drilling and screws, so it is a slower install than peel-and-stick options
- Must be cut to the exact door width with a hacksaw, adding a step for non-standard doors
- A too-low setting drags on the floor and wears the vinyl blade or scratches flooring
A self-adhesive EPDM foam weatherstrip for the wide or uneven gaps that a thin V-seal leaves open - around doors, older windows, and AC units. The rubber foam compresses to fill the gap, stays flexible to -40F, and carries a 10-year flexibility guarantee. Clean the surface well first, since adhesion is the usual failure point.
- Wide gaps
- Drafty doors
- Drafty windows
- Air sealing
Pros
- Compressible EPDM foam fills wide and uneven gaps that thin V-seal cannot
- Rubber stays flexible down to -40F and is warrantied for 10 years
- Peel-and-stick install with scissors; sizes for medium to extra-large gaps
Cons
- Foam is bulkier and less discreet than a folded vinyl V-seal
- Self-adhesive backing can loosen on dusty, cold, or previously painted wood
- Compression seal only; not for the threshold gap under a door (use a sweep)
Frequently Asked Questions
- What weatherstripping should I use for a drafty window?
- A folded vinyl V-seal is the usual pick for double-hung window sashes and jamb gaps. Its hinge compresses to fill the gap while still letting the window open and close. For very wide or uneven gaps, use a compressible EPDM foam tape instead.
- How do I stop cold air coming under my door?
- Install a door sweep on the bottom of the door. A screw-on aluminum-and-vinyl sweep is durable and adjustable for uneven thresholds, which stick-on foam tape and V-seal cannot reach.
- Does self-adhesive weatherstripping last?
- It is the fastest to install but the adhesive can fail after a few seasons, especially on dusty, cold, or painted surfaces. Clean the surface with alcohol first, and choose a screw-mounted sweep for high-wear spots like door bottoms.
