Closes the gap, stops the draught

The whistling, the cold around your ankles, the dust on the floor: it all comes through that small gap under the door. Peel off the liner and stick the seal on: it closes the gap. It blocks wind, dust and even water.

Stick it on and you're done

Measure, cut to length, peel off the liner and stick. The seal is flexible: it fits a door, a sliding window or a shower door.

Keeps insects and dust out

Under a door, the gap also lets in dust and small insects. Once the seal is on, that way in is closed: what's outside stays outside.

There was a gap under the door and when water splashed, it ran all the way to the hardwood. Since I put this on, not a drop gets through. It's matte, you can barely see it. And I think it will stop the draught under the door too.

Handy for lots of things. I buy it again often, and once the surface is degreased, it holds really well.

Really great. Even after peeling it off and sticking it back, it holds well. With other ones, once they're off, that's it. This one has really good glue: I took it off after a few days, it came away clean and stuck back on with no problem. Great!

Works perfectly and sticks well.

T.·16 February 2026

Good quality seal, it really closes the gap around my front door. I recommend it.

L.·29 September 2026

Arrived safely, well packed and delivered quickly, thanks. Good product, I'm happy with it.

C.·3 January 2026

Honestly, it's the best there is. The seal sits against the frame and closes the gap, and when you open the door it moves with it. I've already bought three.

N.·20 September 2026

This isn't the first time I've bought it, it's a good product. Small tip: clean the surface well before sticking it on and it will hold perfectly.

J.·12 September 2026

Sticks very well. I put it along the bottom of my doors to keep insects out.

A.·25 June 2026

This is the third time this year I've bought it to protect my windows from the wind. It really works.

T.·16 March 2026

Arrived quickly, sticks really well. Perfect around the shower.

M.·25 February 2026

It did its job well. My home stays warm longer, and the heating isn't running all the time anymore.

A.·24 February 2026

I put it where the air was getting through. It's nice and wide, which is handy: I took the widest one to close a big gap.

L.·19 February 2026

Holds well. Works against both noise and draughts.

H.·16 February 2026

Much tougher than the ones you find at discount stores. The others peel off fast, this one is really sturdy and sticks perfectly.

E.·15 February 2026

Perfect for sealing doors and windows, and easy to put on. This is the second time I've ordered it.

N.·11 February 2026

I stuck it in the middle of my window, where the two sides meet. It blocks the wind much better than I expected.

M.·30 January 2026

Seems good quality and seals well. Good material.

L.·27 January 2026

Fantastic, I did all my windows with it and the result is impressive.

Y.·24 January 2026

I stuck it on to close the gap at the bottom of the door. The cold winter air doesn't get in anymore, and outside smells have dropped a lot.

M.·22 January 2026

There was a gap at the top of the bedroom door, so I stuck it there. It sticks well and comes off easily.

R.·18 January 2026

Thanks to this seal, no more draughts under my front door, and with almost no effort.

M.·12 January 2026

Excellent seal. I put it on metal doors to keep out the cold, dust and insects, and it does the job very well. Heat, humidity, cold: the glue holds.

N.·8 January 2026

For stopping air around windows and doors, I think it's the best there is.

S.·28 December 2025

Perfect! I put it around my security door to stop draughts, it sticks perfectly 🤩

C.·15 December 2025

Very good, it lets neither dust nor anything else through.

É.·10 December 2025

Sticks very well. Small tip: clean the spot before putting it on.

C.·2 December 2025

Good product, I'd bought it before. Just remember to dust well before putting it on.

C.·26 November 2025

Very good, I'd bought it before. Thanks so much.
