Cold air creeps in under the door while you freeze and the heating gets louder.
On cold days, you feel it immediately: The warmth in the room escapes through the gap under the door, the floor gets cold, and the heating costs rise anyway. This door seal is simply slid under the door – no drilling, no tools – and stops the draft in seconds. The result: noticeably warmer rooms and a heating system that no longer has to fight against the gap.



Pro tip: Always cut the seal 1–2 cm shorter than the door width to ensure the door can still open easily and the seal does not get stuck or shift over time.
