Under-Door Seal – Closes the Gap From Both Sides at Once

A twin-sided strip that slides beneath a closed door and sits flat against the floor on either face. It suits doors 3.5 to 5.5 cm thick and cuts down with scissors to a width of up to 93 cm. The foam core blocks air, softens sound and keeps dust out of the room.

Why choose this door seal?

A centimeter of daylight under a door moves more air than it has any right to, and you feel every bit of it at ankle level. Closing that gap costs almost nothing and changes the room. This one needs no drill and comes straight back out in spring.

• Foam core: fills the gap and compresses instead of scraping when the door swings.
• Both faces sealed: one strip closes the inside and the outside of the gap together.
• Cuts to fit: scissors and a tape measure, up to 93 cm, no other tools involved.
• Wipe-clean cover: a tightly woven outer layer that takes a damp cloth.
• Move it anywhere: lift it out and put it under a different door whenever you like.

A quieter room and no cold line running across the floor.

Measure the door width and trim the strip before you fit it, since taking off too little is easier to fix than too much. Slide it under the closed door and push until both sides lie flat. Wood, tile and low-pile carpet are all fine; very deep pile may need the door lifted a little on the first pass.
